A typical OS imposed limit is 1024 open FD, which can bee too low when
there are hundreds of concurrent voice calls.
In systemd service file, set a super high limit of 65536.
In osmo-mgw's user manual, add section 'Configure limits' describing
this in detail.

This is a special endpoint which can always be audited. This is useful
for clients who wish to submit requests to osmo-mgw periodically to find
out whether the MGW is still reachable. This endpoint will be used by
libomso-mgcp-client as default target endpoint to implement such
feature.
This "null" Endpoint is osmo-mgw specific, not described in MGCP specs.

When configuring osmo-mgw the user may choose an arbitrary trunk number
for the E1 trunk and sets a line number that must match the number of
the physical line that is used with the particular trunk. This is easy
to confuse, so lets add a note to the maual that mekes this clear.

We have VTY options that allow to set the DSCP value. However, we
then call a function to set the TOS bits in the kernel. This is
very wrong. The DSCP is only the upper 6 bits of the 8-bit TOS
value, and hence we are mussing that translation.
As libosmocore now has a helper function osmo_sock_set_dscp(),
let's make use of it and don't care about the low-level details.
However, this means we need to finally remove the deprecated
alias for "rtp ip-tos <0-255>".

The manual does not say much about the endpoint naming, even though
osmo-mgw is oriented at RFC 3435 the endpoint names are specific to
osmo-mgw. In particular the E1/T1 endpoints and their overlapping need
some explaination

The cunfiguration chapter does not say anything about E1 trunk
configurations, lets add a subsection that explains how an E1
trunk is added.

The trunk 0 was reserved for rtpbridge in earlier versions of osmo-mgw,
this was due to internal technical limitations which no longer exist.

Add a graph similar to "OsmoMGW used with OsmoMSC" that shows the
integration of a legacy E1 BTS into a AoIP network
Change-Id: I71dc2f4a188fbc25e81050be3dd4c83e1797e63d
The graph "OsmoMGW used with OsmoMSC" shows a BSC entity that accepts
AoIP and RTP, however osmo-bsc has no RTP proxy functionality. It makes
probably more sense to remove the BTS from the graph and call "BSC" "2G
BSS"
Change-Id: I6c7d26b6e45d0f953b82bca3ae7b2f26600982b2
The graph "OsmoMGW used with OsmoBSC" shows an RTP and 3GPP AoIP going
to OsmoMSC, this is technically wrong since osmoMSC has no RTP proxy
functionality whatsoever. Since the graph is not so much about OsmoMSC
it makes more sense to label OsmoMSC with "core-network", then it makes
sense and correctly highlights the role of osmo-mgw on the BSS side.

The limitations section is outdated. We now have support for osmux and
E1 timeslots with trau frames. However, we did not mention that we still
have no transcoding as well.

See also Ia6fe5ead4b601931c1bf41b29fc1b237aac37d2c in osmo-mgw.git, which
changes the initial single-character implementation to match this specification
of string tokens separated by spaces.
