So far, patches have set up rtp_stream to allow setting multiple codecs, and collected the codecs information into the codecs filter struct. Now actually use the codecs filter result to choose a codec. The resulting codecs behavior is tested in upcoming patch I879ec61f523ad4ffc69a0b02810591f7c0261ff9. (The test ideally should have come before this patch, but my time to rework this branch is up.) With the codecs filter in place, we are ready for sending and receiving full SDP via MNCC, see upcoming Ie0668c0e079ec69da1532b52d00621efe114fc2c and Ie433db1ba0c46d4b97538a969233c155cefac21c Related: SYS#5066 Change-Id: I66e7c8c5e401f4f3a7d3d42b9525b2c6e99691d9 |

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 Open Source Mobile Communications project.
OsmoMSC exposes
- A over IP towards BSCs (e.g. OsmoBSC): 3GPP AoIP or SCCPlite
- IuCS over IP towards RNCs / HNBGW (e.g. osmo-hnbgw)
- 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)
- USSD (exposed via GSUP)
- SMS (either via built-in SMSC or external via GSUP)

History
OsmoMSC originated from the 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.
