-About OpenBSC
-=============
-
-OpenBSC is a minimalistic implementation of the GSM Network, with
-particular emphasis on the functionality typically provided by the BSC,
-MSC, HLR, VLR and SMSC.
-
-Its currently supported interfaces towards the BTS are:
-
- * Classic A-bis over E1 using a mISDN based E1 interface. In other
-   words, you can connect existing GSM Base Transceiver Station (BTS)
-   through E1 to OpenBSC.  So far, we have only tested the Siemens BS-11
-   Test reports with other BTS are much appreciated!
-
- * A-bis over IP as used by the ip.access nanoBTS product family
-
-You can find the project documentation at http://openbsc.gnumonks.org/
-
-This project is still in its early days, and there are lots of areas where it
-doesn't behave as per GSM spec.
-

-libosmocore
-===========
-
-Please note that as of March 2010, OpenBSC has a dependency to a library
-called "libosmocore".  You can obtain that library from
-
-	git://git.osmocom.org/libosmocore.git

+osmo-msc - Osmocom MSC Implementation
+=====================================
+
+This repository contains a C-language implementation of a GSM **Mobile Switching
+Centre (MSC)** for 2G (GSM) and 3G (UMTS).  It is part of the
+[Osmocom](https://osmocom.org/) Open Source Mobile Communications
+project.
+
+OsmoMSC exposes
+
+ * *A over IP* towards BSCs (e.g. [osmo-bsc](https://osmocom.org/projects/osmobsc/wiki): 3GPP AoIP or SCCPlite
+ * *IuCS over IP* towards RNCs / HNBGW (e.g. [osmo-hnbgw](https://osmocom.org/projects/osmohnbgw/wiki))
+ * *MGCP* towards a co-located [osmo-mgw](https://osmocom.org/projects/osmo-mgw/wiki) for the RTP streams
+ * *[GSUP](https://osmocom.org/projects/cellular-infrastructure/wiki/GSUP)* (instead of 3GPP MAP) towards [osmo-hlr](https://osmocom.org/projects/osmo-hlr/wiki)
+ * *SMPP* towards any external SMS sending/receiving applications
+ * *[MNCC](https://osmocom.org/projects/osmomsc/wiki/MNCC)* as external call-control interface towards e.g.
+   [osmo-sip-connectr](https://osmocom.org/projects/osmo-sip-conector/wiki)
+ * The Osmocom typical telnet *VTY* and *CTRL* interfaces.
+ * The Osmocom typical *statsd* exporter.
+
+OsmoMSC implements
+
+ * mobility management
+ * call control (either via built-in MNCC handler or external osmo-sip-connector)
+ * voice group call ([VGCS](https://osmocom.org/projects/cellular-infrastructure/wiki/Voice_Group_Call)) and
+   voice broadcast calls ([VBS](https://osmocom.org/projects/cellular-infrastructure/wiki/Voice_Broadcast_Call)) as used in GSM-R
+ * USSD (exposed via GSUP)
+ * SMS (either via built-in SMSC or external via GSUP)

+
+
+History
+-------
+
+OsmoMSC originated from the [OsmoNITB](https://osmocom.org/projects/osmonitb/wiki/OsmoNITB)
+project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OsmoNITB had
+reached maturity and diversity (including M3UA SIGTRAN and 3G support in the form of IuCS and IuPS interfaces)
+that naturally lead to a separation of the all-in-one approach to fully independent separate programs as in
+typical GSM networks.
+
+OsmoMSC was one of the parts split off from the old openbsc.git.

+Description: OsmoMSC: Osmocom's Mobile Switching Center for 2G and 3G circuit-switched mobile networks
+  The Mobile Switching Center (MSC) is the heart of 2G/3G
+  circuit-switched services.  It terminates the A-interface links from the
+  Base Station Controllers (BSC) and handles the MM and CC sub-layers of
+  the Layer 3 protocol from the phones (MS).
+  .
+  This Osmocom implementation of the MSC handles A interfaces via 3GPP
+  AoIP in an ASP role.  It furthermore implements IETF MGCP against an
+  external media gateway, such as OsmoMGW.  It does *not* implement MAP
+  towards a HLR, but the much simpler Osmocom GSUP protocol, which can
+  be translated to MAP if needed.

+Description: OsmoMSC: Osmocom's Mobile Switching Center for 2G and 3G circuit-switched mobile networks
+  The Mobile Switching Center (MSC) is the heart of 2G/3G
+  circuit-switched services.  It terminates the A-interface links from the
+  Base Station Controllers (BSC) and handles the MM and CC sub-layers of
+  the Layer 3 protocol from the phones (MS).
+  .
+  This Osmocom implementation of the MSC handles A interfaces via 3GPP
+  AoIP in an ASP role.  It furthermore implements IETF MGCP against an
+  external media gateway, such as OsmoMGW.  It does *not* implement MAP
+  towards a HLR, but the much simpler Osmocom GSUP protocol, which can
+  be translated to MAP if needed.
+  .
+  This package contains the debug symbols for osmo-msc in order to
+  generate meaningful backtraces in bug-reports.

+ This script is derived from GIT-VERSION-GEN from GIT: http://git.or.cz/.
+ It may be run two ways:
+ - from a git repository in which the "git describe" command below
+ produces useful output (thus requiring at least one signed tag)
+ - from a non-git-repo directory containing a .tarball-version file, which
+ presumes this script is invoked like "./git-version-gen .tarball-version".
+ .
+ In order to use intra-version strings in your project, you will need two
+ separate generated version string files:
+ .
+ .tarball-version - present only in a distribution tarball, and not in
+ a checked-out repository.  Created with contents that were learned at
+ the last time autoconf was run, and used by git-version-gen.  Must not
+ be present in either $(srcdir) or $(builddir) for git-version-gen to
+ give accurate answers during normal development with a checked out tree,
+ but must be present in a tarball when there is no version control system.
+ Therefore, it cannot be used in any dependencies.  GNUmakefile has
+ hooks to force a reconfigure at distribution time to get the value
+ correct, without penalizing normal development with extra reconfigures.
+ .
+ .version - present in a checked-out repository and in a distribution
+ tarball.  Usable in dependencies, particularly for files that don't
+ want to depend on config.h but do want to track version changes.
+ Delete this file prior to any autoconf run where you want to rebuild
+ files to pick up a version string change; and leave it stale to
+ minimize rebuild time after unrelated changes to configure sources.
+ .
+ It is probably wise to add these two files to .gitignore, so that you
+ don't accidentally commit either generated file.
+ .
+ Use the following line in your configure.ac, so that $(VERSION) will
+ automatically be up-to-date each time configure is run (and note that
+ since configure.ac no longer includes a version string, Makefile rules
+ should not depend on configure.ac for version updates).

-License:
-
-                    GNU AFFERO GENERAL PUBLIC LICENSE
-                       Version 3, 19 November 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU Affero General Public License is a free, copyleft license for
-software and other kinds of works, specifically designed to ensure
-cooperation with the community in the case of network server software.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-our General Public Licenses are intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  Developers that use our General Public Licenses protect your rights
-with two steps: (1) assert copyright on the software, and (2) offer
-you this License which gives you legal permission to copy, distribute
-and/or modify the software.
-
-  A secondary benefit of defending all users' freedom is that
-improvements made in alternate versions of the program, if they
-receive widespread use, become available for other developers to
-incorporate.  Many developers of free software are heartened and
-encouraged by the resulting cooperation.  However, in the case of
-software used on network servers, this result may fail to come about.
-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
-
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.
-
-  An older license, called the Affero General Public License and
-published by Affero, was designed to accomplish similar goals.  This is
-a different license, not a version of the Affero GPL, but Affero has
-released a new version of the Affero GPL which permits relicensing under
-this license.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU Affero General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Remote Network Interaction; Use with the GNU General Public License.
-
-  Notwithstanding any other provision of this License, if you modify the
-Program, your modified version must prominently offer all users
-interacting with it remotely through a computer network (if your version
-supports such interaction) an opportunity to receive the Corresponding
-Source of your version by providing access to the Corresponding Source
-from a network server at no charge, through some standard or customary
-means of facilitating copying of software.  This Corresponding Source
-shall include the Corresponding Source for any work covered by version 3
-of the GNU General Public License that is incorporated pursuant to the
-following paragraph.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the work with which it is combined will remain governed by version
-3 of the GNU General Public License.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU Affero General Public License from time to time.  Such new versions
-will be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU Affero General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU Affero General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU Affero General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU Affero General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU Affero General Public License for more details.
-
-    You should have received a copy of the GNU Affero General Public License
-    along with this program.  If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If your software can interact with users remotely through a computer
-network, you should also make sure that it provides a way for users to
-get its source.  For example, if your program is a web application, its
-interface could display a "Source" link that leads users to an archive
-of the code.  There are many ways you could offer source, and different
-solutions will be better for different programs; see section 13 for the
-specific requirements.
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU AGPL, see
-<http://www.gnu.org/licenses/>.

+[[net]]
+== Configuring the Core Network
+
+The core network parameters are configured by the config file (as in `osmo-msc
+-c osmo-msc.cfg`). The config file is parsed by the VTY, which is also
+available via telnet in the running `osmo-msc` instance. Be aware that even
+though you may be able to change these parameters without restarting
+`osmo-msc`, some may not take immediate effect, and it is safest to use the
+config file to have these parameters set at startup time.
+
+The core network parameters are found in the `config` / `network`.
+
+A full reference to the available commands can be found in the _OsmoMSC VTY
+reference manual_ <<vty-ref-osmomsc>>. This section describes only the most
+commonly used settings.
+
+Here is an overview of the config items, described in more detail below:
+
+----
+network
+ network country code 262
+ mobile network code 89
+ mm info 1
+ short name OsmoMSC
+ long name OsmoMSC
+ authentication required
+ encryption a5 3
+----
+
+[TIP]
+====
+Use the telnet VTY interface to query the current configuration of a running
+`osmo-msc` process:
+
+----
+$ telnet localhost 4254
+OsmoMSC> enable
+OsmoMSC# show running-config
+----
+
+Some parameters may be changed without restarting `osmo-msc`. To reach the
+`network` node, enter:
+
+----
+OsmoMSC> enable
+OsmoMSC# configure terminal
+OsmoMSC(config)# network
+OsmoMSC(config-net)# short name Example-Name
+OsmoMSC(config-net)# exit
+OsmoMSC(config)#
+----
+
+The telnet VTY features tab-completion as well as context sensitive help shown
+when entering a `?` question mark.
+
+You can always use the `list` VTY command or enter `?` on the blank prompt to
+get a list of all possible commands at the current node.
+====
+
+
+=== MCC/MNC
+
+The key identities of every GSM PLMN is the Mobile Country Code and the Mobile
+Network Code. They are identical over the entire network. In most cases, the
+MCC/MNC will be allocated to the operator by the respective local regulatory
+authority. For example, to set the MCC/MNC of 262-89, have this in your
+osmo-msc.cfg:
+
+----
+network
+ network country code 262
+ mobile network code 89
+----
+
+
+=== Configuring MM INFO
+
+The _MM INFO_ procedure can be used after a successful _LOCATION UPDATE_ in
+order to transmit the human-readable network name as well as local time zone
+information to the MS.  By default, _MM INFO_ is not active, i.e. `0`. Set to `1`
+to activate this feature:
+
+----
+network
+ mm info 1
+ short name OsmoMSC
+ long name OsmoMSC
+----
+
+[NOTE]
+====
+Not all phones support the MM INFO procedure. If a phone is not
+factory-programmed to contain the name for your MCC/MNC, it will likely only
+provide a numeric display of the network name, such as _262-89_, or show the
+country code transformed into a letter, such as _D 89_.
+====
+
+The time information transmitted is determined by the local system time of the
+operating system on which OsmoMSC is running.
+
+
+=== Authentication
+
+A subscriber's IMSI must be entered in the HLR database to be able to attach. A
+subscriber-create-on-demand feature is also available, see the _OsmoHLR
+reference manual_ <<userman-osmohlr>>.
+
+A known IMSI in the HLR may or may not have authentication keys associated,
+which profoundly affects the ability to attach and the algorithms used to
+negotiate authentication, as the following sections explain for 2G and 3G.
+
+==== Authentication on 2G
+
+If authentication tokens (such as KI for 2G, or K and OP/OPC for UMTS) are
+present in the HLR, OsmoMSC will only attach a subscriber after successful
+authentication. Note that the 3G authentication keys are also used on 2G when
+the MS indicates UMTS AKA capability, in which case the full UMTS style mutual
+authentication may indeed take place on 2G (GERAN).
+
+On 2G, if no authentication keys are present in the HLR for a given subscriber,
+OsmoMSC will attach the subscriber _without_ authentication. Subscribers that
+lack authentication keys can always be rejected with this setting:
+
+----
+network
+ authentication required
+----
+
+==== Authentication on 3G
+
+3G (UTRAN) always requires authentication (a.k.a. Integrity Protection) by
+specification, and hence authentication keys must be present in the HLR for a
+subscriber to be able to attach on 3G.
+
+OsmoMSC always indicates UIA1 and UIA2 as permitted Integrity Protection
+algorithms on 3G.
+
+=== Ciphering
+
+To enable ciphering on the radio link, authentication must take place first:
+the Kc resulting from authentication is the key used for ciphering. Hence, to
+be able to use ciphering, a subscriber must have authentication tokens
+available in the HLR.
+
+==== Ciphering on 2G
+
+The MS, BTS and MSC must agree on a ciphering algorithm to use.
+
+- The MS sends its supported ciphering algorithms via Classmark IEs during
+  Location Updating.
+- Typically the BSC needs to know which A5 ciphers are supported by connected
+  BTSes, see the `network / encryption a5` configuration item for OsmoBSC
+  <<vty-ref-osmobsc>>.
+- Finally, OsmoMSC may impose that specific A5 ciphers shall not be considered.
+
+It is the responsibility of the BSC to then pick an A5 cipher that satisfies
+all requirements.
+
+- In OsmoMSC, A5/0 means that ciphering is turned off.
++
+----
+network
+ encryption a5 0
+----
+
+- A5/1 and A5/3 are currently supported by Osmocom.
++
+----
+network
+ encryption a5 1 3
+----
+
+- Never use A5/2: it is an "export grade cipher" and has been deprecated for
+  its low ciphering strength.
+
+- To allow either no encryption or any of A5/1 or A5/3 based on the presence of
+  authentication keys and abilities of the MS, SIM and BSC configuration, it is
+  recommended to enable all ciphers in OsmoMSC. The highest available A5 cipher
+  will be used; the order in which the A5 options are configured does not
+  affect the choice.
++
+----
+network
+ encryption a5 0 1 3
+----
+
+==== Ciphering on 3G
+
+While authentication is always required on 3G, ciphering is optional.
+
+So far OsmoMSC allows switching ciphering on 3G either on or off -- the default
+behavior is to enable ciphering. (Individual choice of algorithms may be added
+in the future.)
+
+Disable 3G ciphering:
+
+----
+network
+ encryption uea 0
+----
+
+Enable 3G ciphering (default):
+
+----
+network
+ encryption uea 1 2
+----
+
+OsmoMSC indicates UEA1 and UEA2 as permitted encryption algorithms on 3G.

+=== Osmux Support in {program-name}
+
+==== {program-name} in a A/IP with IPA/SCCPlite network setup
+
+In this kind of setup, the CN side of BSC co-located MGW is managed by the MSC,
+meaning the use of Osmux is transparent to BSC since MSC takes care of both peer
+MGW connections. Moreover, in this case the MSC has no dynamic information on
+Osmux support in the BSC co-located MGW until `CRCX` time, which means
+configuration on both nodes need to be carefully set up so they can work
+together.
+
+Osmux usage in {program-name} in managed through the VTY command `osmux
+(on|off|only)`. Since there's no dynamic information on Osmux support, it may be
+required in the future to have an extra VTY command which can be set per BSC to
+fine-tune which ones should use Osmux and which shouldn't.
+
+{program-name} will behave differently during call set up based on the VTY
+command presented above:
+
+* `off`: {program-name} won't include an `X-Osmux` extension to `CRCX` sent to
+  the BSC co-located MGW when configuring the CN side of the MGW endpoint. If
+  the MGW answers with a `CRCX ACK` containing an `X-Osmux`, {program-name} will
+  cancel the call establishment.
+* `on`: {program-name} will initially configure its co-located MGW to use Osmux, then
+  similarly send a `CRCX` with an `X-Osmux` extension towards the BSC co-located
+  MGW. Under this configuration, if the BSC co-located MGW didn't support Osmux,
+  it could send a `CRCX ACK` without `X-Osmux` extension or fail (depending on
+  its own configuration), and {program-name} could choose to re-create its local
+  connection as non-Osmux (RTP) (and possibly try again against BSC co-located
+  MGW), but this behavior is currently not implemented. As a result, currently
+  `on` behaves the same as `only`.
+* `only`: {program-name} will configure its co-located MGW as well as the BSC
+  co-located MGW to use Osmux by including the `X-Osmux` MGCP extension. If MGW
+  rejects to use Osmux, {program-name} will reject the call and the call
+  establishment will fail.
+
+==== {program-name} in a 3GPP AoIP network setup
+
+Osmux usage in {program-name} in managed through the VTY command `osmux
+(on|off|only)`. Once enabled (`on` or `only`), {program-name} will start
+appending the vendor specific _Osmux Support_ IE in _BSSMAP RESET_ and _BSSMAP
+RESET-ACK_ message towards the BSC in order to announce it supports Osmux, and
+BSC will do the same. This way, {program-name} can decide whether to use Osmux
+or not based on this information when setting up a call (this time using _Osmux
+CID_ IE). It should be noted that this option should not be enabled unless BSCs
+managed by {program-name} support handling this extension IE (like OsmoBSC),
+3rd-party BSCs might otherwise refuse the related _RESET_/_RESET-ACK_ messages.
+
+{program-name} will behave differently during call set up based on the VTY
+command presented above:
+
+* `off`: {program-name} won't use Osmux. That is, it will send a _BSSMAP Assign
+  Request_ without the _Osmux CID_ IE, and will send a `CRCX` without `X-Osmux`
+  extension towards its co-located MGW.
+* `on`: If BSC announced Osmux support to {program-name} during _BSSMAP RESET_
+  time, then {program-name} will set up the call to use Osmux (by adding
+  `X-Osmux` to MGCP `CRCX` and _Osmux CID_ IE to _BSSMAP Assign Request_). If
+  the BSC didn't announce Osmux support to {program-name}, then {program-name}
+  will use RTP to set up the call (by avoiding addition of previously described
+  bits).
+* `only`: Same as per `on`, except that {program-name} will allow to set up only
+  Osmux calls on the CN-side, this is, it will reject to set up voice calls for
+  BSC which didn't announce Osmux support.

+== Overview
+
+This manual should help you getting started with OsmoMSC. It will cover
+aspects of configuring and running the OsmoMSC.
+
+[[intro_overview]]
+=== About OsmoMSC
+
+OsmoMSC is the Osmocom implementation of a Mobile Switching Center (MSC) for 2G
+and 3G GSM and UMTS mobile networks. Its interfaces are:
+
+- GSUP towards OsmoHLR (or a MAP proxy);
+- A over IP towards a BSC (e.g. OsmoBSC);
+- IuCS towards an RNC or HNB-GW (e.g. OsmoHNBGW) for 3G voice;
+- MNCC (Mobile Network Call Control derived from GSM TS 04.07);
+- SMPP 3.4 (Short Message Peer-to-Peer);
+- The Osmocom typical telnet VTY and CTRL interfaces.
+
+OsmoMSC originated from the OpenBSC project, which started as a minimalistic
+all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
+maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
+IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
+approach to fully independent separate programs as in typical GSM networks.
+Before it was split off, OsmoMSC originated from libmsc of the old openbsc.git.
+Since a true _A_ interface and IuCS for 3G support is available, OsmoMSC
+exists only as a separate standalone entity.
+
+Key differences of the new OsmoMSC compared to the old OsmoNITB are:
+
+- The complete VLR implementation that communicates with the separate HLR
+  (OsmoHLR) for subscriber management. In contrast to the OsmoNITB, HLR queries
+  are fully asynchronous, and the separate HLR allows using centralized
+  subscriber management for both circuit-switched and packet-switched domains
+  (i.e. one OsmoHLR for both OsmoMSC and OsmoSGSN).
+
+- VLR and HLR brought full UMTS AKA (Authentication and Key Agreement) support,
+  i.e. Milenage authentication in both the full 3G variant as well as the
+  backwards compatible 2G variant.
+
+- Addition of a true _A_ interface for 2G voice services. Previously, OsmoBSC
+  had an SCCPlite based _A_ interface towards 3rd party MSC implementations.
+  OsmoMSC features a true SCCP/M3UA _A_ interface, which allows running OsmoBSC
+  against this Osmocom based MSC implementation. The new SCCP/M3UA SIGTRAN for
+  the _A_ interface is implemented in libosmo-sccp, which is used by OsmoMSC
+  and OsmoBSC (and others), to establish a link via an STP (e.g. OsmoSTP).
+
+- Addition of an _IuCS_ interface to allow operating 3G voice services, also
+  via SCCP/M3UA SIGTRAN, for example connecting via OsmoHNBGW to a 3G small
+  cell device.

+=== Software Components
+
+This is a brief description of OsmoMSC's internal software components.
+
+==== SMSC
+
+A minimal store-and-forward server for SMS, supporting both MO and MT
+SMS service, as well as multi-part messages.
+
+The built-in SMSC also supports an external SMSC interface.  For more
+information, see <<smpp>>.
+
+==== MSC
+
+The MSC component implements the mobility management (MM) functions of the TS
+04.08 and delegates to SMSC for SMS message handling and the VLR for subscriber
+management.
+
+Furthermore, it can handle TS 04.08 Call Control (CC), either by use of
+an internal MNCC handler, or by use of an external MNCC agent.  For more
+information see <<mncc>>.
+
+==== VLR
+
+A fully featured Visitor Location Register handles the subscriber management
+and authentication, and interfaces via GSUP to the external HLR.

+
+
+=== Multiple instances
+
+Running multiple instances of `osmo-msc` on the same computer is possible if all
+interfaces (VTY, CTRL) are separated using the appropriate configuration
+options. The IP based interfaces are binding to local host by default. In order
+to separate the processes, the user has to bind those services to specific but
+different IP addresses and/or ports.
+
+The VTY and the Control interface can be bound to IP addresses from the loopback
+address range, for example:
+
+----
+line vty
+ bind 127.0.0.2
+ctrl
+ bind 127.0.0.2
+----
+
+If external SMPP is enabled, you may bind it to a different interface using:
+
+----
+smpp
+ local-tcp-ip 10.23.42.1 2775
+----
+
+More on SMPP configuration in <<smpp-config-global>>.
+
+The external MNCC handler is a UNIX domain socket that is created when external MNCC handling is configured. A separate
+path must be used per osmo-msc instance:
+
+----
+msc
+ mncc external /tmp/mncc_socket
+----
+
+More on MNCC in <<mncc-external>>.
+
+The SGs interface by default listens on 0.0.0.0:29118 (SCTP). Each instance of OsmoMSC must use a different IP address
+and/or port. For details about the configuration of the SGs interface, see section <<sgs>>.
+
+For the following links, OsmoMSC acts as a client and does not listen/bind to a
+specific interface, and will hence not encounter conflicts for multiple instances
+running on the same interface:
+
+- The SCCP/M3UA links are established by OsmoMSC contacting an STP.
+- The GSUP link is established by OsmoMSC contacting an HLR.
+- The MGCP link is established by OsmoMSC contacting an MGW.
+
+
+=== Configure primary links
+
+==== Configure SCCP/M3UA to accept _A_ and _IuCS_ links
+
+OsmoMSC acts as client to contact an STP instance and establish an SCCP/M3UA
+link.
+
+An example configuration of OsmoMSC's SCCP link:
+
+----
+cs7 instance 0
+ point-code 0.23.1
+ asp asp-clnt-OsmoMSC-A-Iu 2905 0 m3ua
+  remote-ip 127.0.0.1
+  role asp
+  sctp-role client
+----
+
+This configuration is explained in detail in <<cs7_config>>.
+
+Note that _A_ and _IuCS_ may use different SCCP instances, if so desired:
+
+----
+cs7 instance 0
+ asp my-OsmoMSC-A 2905 0 m3ua
+  remote-ip 10.23.42.1
+  role asp
+  sctp-role client
+cs7 instance 1
+ asp my-OsmoMSC-Iu 2905 0 m3ua
+  remote-ip 10.23.42.2
+  role asp
+  sctp-role client
+msc
+ cs7-instance-a 0
+ cs7-instance-iu 1
+----
+
+==== Configure GSUP to reach the HLR
+
+OsmoMSC will assume a GSUP server (OsmoHLR) to run on the local host and the
+default GSUP port (4222). Contacting an HLR at a different IP address can be
+configured as follows:
+
+----
+hlr
+ ! IP address of the remote HLR:
+ remote-ip 10.23.42.1
+ ! default port is 4222, optionally configurable by:
+ remote-port 1234
+----
+
+==== Configure MGCP to connect to an MGW
+
+OsmoMSC uses a media gateway (typically OsmoMGW) to direct RTP streams. By
+default, an MGW is expected to receive MGCP requests on the IANA-registered
+default port for MGCP (2427) on local host (127.0.0.1).
+
+Here is an example configuration for a remote MGW:
+
+----
+network
+ mgw 0
+  remote-ip 10.9.8.7
+  remote-port 2427
+  reset-endpoint rtpbridge/* <1>
+----
+<1> The 'reset-endpoint' setting instructs the OsmoMGW to send a wildcarded
+DLCX to the media gateway. This helps to clear lingering calls from the
+media gateway when the OsmoMSC is restarted.
+
+OsmoMSC is also able to handle a pool of media gateways for load
+distribution. See also <<mgw_pooling>>.
+
+[NOTE]
+====
+Previous versions of OsmoMSC (1.9.0 and below) didn't have the 'mgw' VTY node and
+hence didn't support the MGW pooling feature. Therefore, historically the MGW
+related commands where placed under the `msc` VTY node. The MGW related commands
+under the  `msc` VTY are still parsed and used but its use is deprecated and
+hence discouraged in favour of the new `mgw` node. Writing the config to a file
+from within OsmoMSC will automatically convert the config to use the new `mgw`
+node.

+[[sgs]]
+== SGs interface
+
+OsmoMSC offers an SGs interface using the SGsAP protocol. The SGs interface is an
+optional interface between a 2G (GERAN) / 3G (UTRAN) MSC and an 4G (EUTRAN) MME.
+Its purpose is to facilitate both CSFB (Circuit-Switched Fall Back) and SMSoS
+(SMS over SGs). It is used for Mobility management (MM) and paging procedures
+between the EPS (Evolved Packet Services) and CS (Circuit Switched) domain.
+
+=== VTY configuration
+
+The SGs interface implementation in OsmoMSC is automatically active and requires
+only minimal configuration. When no specific configuration is provided OsmoMSC
+will listen on 0.0.0.0:29118 (SCTP) for incoming connections.
+
+This is sufficient in the most configurations, but in larger installations,
+where services are either tied to specific interfaces and/or more instances of
+OsmoMSC run in parallel, a custom configuration is necessary.
+
+The user has the option to configure the IP address (`local-ip`) and the SCTP
+port (`local-port`) and also the `vlr-name` that OsmoMSC uses to identify itself
+towards the MME. It should be noted that the `vlr-name` is usually the DNS name
+for the IP address of the VLR/MSC, so IP address used and the `vlr-name` should
+match the DNS server entry.
+
+----
+sgs
+ local-ip 127.0.0.1
+ local-port 29118
+ vlr-name vlr.example.net
+----
+
+In order to fine tune the behavior of the SGs interface the user also has
+control over the relevant timers (`ts5`, `ts6-2`, `ts7`, `ts11`, `ts14`, `ts15`)
+and counters (`ns7`, `ns11`). Each timer and counter has to be configured
+separately. In the following example we change the value of ts and ns11.
+
+----
+sgs
+ timer ts7 23
+ counter ns11 100
+----
+
+
+[NOTE]
+====
+In case multiple instances of OsmoMSC run in parallel, it is advised to use a
+different `vlr-name` for each instance. In any case it must be ensured that the
+SGs interface of each instance is bound to a different IP address and/or port.
+====
+
+=== Connection monitoring
+
+The user can use the VTY command `show sgs-connections` to list the MMEs that
+are currently connected to OsmoMSC.

+
+# This script is derived from GIT-VERSION-GEN from GIT: http://git.or.cz/.
+# It may be run two ways:
+# - from a git repository in which the "git describe" command below
+#   produces useful output (thus requiring at least one signed tag)
+# - from a non-git-repo directory containing a .tarball-version file, which
+#   presumes this script is invoked like "./git-version-gen .tarball-version".
+
+# In order to use intra-version strings in your project, you will need two
+# separate generated version string files:
+#
+# .tarball-version - present only in a distribution tarball, and not in
+#   a checked-out repository.  Created with contents that were learned at
+#   the last time autoconf was run, and used by git-version-gen.  Must not
+#   be present in either $(srcdir) or $(builddir) for git-version-gen to
+#   give accurate answers during normal development with a checked out tree,
+#   but must be present in a tarball when there is no version control system.
+#   Therefore, it cannot be used in any dependencies.  GNUmakefile has
+#   hooks to force a reconfigure at distribution time to get the value
+#   correct, without penalizing normal development with extra reconfigures.
+#
+# .version - present in a checked-out repository and in a distribution
+#   tarball.  Usable in dependencies, particularly for files that don't
+#   want to depend on config.h but do want to track version changes.
+#   Delete this file prior to any autoconf run where you want to rebuild
+#   files to pick up a version string change; and leave it stale to
+#   minimize rebuild time after unrelated changes to configure sources.
+#
+# It is probably wise to add these two files to .gitignore, so that you
+# don't accidentally commit either generated file.
+#
+# Use the following line in your configure.ac, so that $(VERSION) will
+# automatically be up-to-date each time configure is run (and note that
+# since configure.ac no longer includes a version string, Makefile rules
+# should not depend on configure.ac for version updates).
+#
+# AC_INIT([GNU project],
+#         m4_esyscmd([build-aux/git-version-gen .tarball-version]),
+#         [bug-project@example])
