This can be used for the fsm instance ID before we know the IMSI.

OsmoMSC is using whatever reject cause is apropriate in the given
situation. This user-configurable reject cause only had relevance
in OsmoNITB, and hence it is an unused parameter that can be removed
in OsmoMSC.

When we receive bearer capabilities from MNCC and encode thme into
a CC message, we have to also update our "cache" inside 'struct
gsm_trans'. Only that way, the BSSMAP ASSIGNMENT code is aware of
the actual current/present bearer capabilities such as permitted speech
codecs.
This will in practise only work if the related CC/MNCC message with
berer_cap IE will happen before the MSC performs the BSSMAP ASSIGNMENT
procedure. Our logic still needs to change in a way that the CC/MNCC
code in gsm_04_08.c detects if trans->bearer_cap != new bearer_cap, and
in that case triggers a new follow-up BSSMAP ASSIGNMENT.

When we receive a MNCC_SETUP_REQ primitive from the external MNCC
handler, we must not only encode it into the TS 04.08 CC SETUP, but
also keep it around in the "trans" structure representing this voice
call, as it is needed e.g. at BSSMAP ASSIGNMENT time.

We cannot use conn->a.conn_id after conn has been free'd inside
msc_clear_request(). Let's store conn_id before that call to
ensure we avoid an use-after-free situation.
A more elegant (but more intrusive) solution would be to
move the SCCP connection clearing into the FSM itself.

As in GSM/3GPP networks emergency calls carry no explicit destination
number/address, add a VTY commadn to patch in some destination handler

When we receive a msgb-wrapped primitive from the SCCP provider (stack),
it transfers msgb ownership to us (the SCCP user). The existing code
passed the msgb ownership down into all the various downstream
functions, which each then had to take care of msgb free'ing.
Not all of the paths did eventually free the msgb. And at least one
path used data from the primitive *after* the free
Let's restructure this in a way that no msgb ownership is transferred
down the call chain. Instead, there's one common msgb_free() in
sccp_sap_up(). We can do this as nobody is queueing or otherwise
keeping the msgb.

Having all BSSAP related logs in the "DMSC" category is overly

There's little point in resolving the gsm_subscriber_connection in each

resolve it once and dispatch the already-resolved conn into the

Clean up the log statements in a_iface*.c, which was very inconsistent.
For example "BSC sending" is very confusing. We are receiving from the BSC,
and it did already send the message, it is no longer in the process of
sending it if we have already received it in the MSC.

If the BSC is contacting us for the first time and sending a BSSMAP
RESET, then we should simply ACK that and transition into the
"connected" state, where connection-oriented and connectionless
procedures are permitted.
This patch is a bit large for such a seemingly simple behavioural
change, but the existing data model didn't permit a more
straight-forward implementation.

Using this argument we can create the state machine in the

It is quite important to have some way of runtime state introspection
about the major objects inside osmo-msc. This patch adds some basic

The MGCP FSM implements a timeout when waiting for the RAN to complete
the call (assignment complete, alerting, connect...). This timeout
is currently set to 10sec. This means if the other end did not pick
up after 10sec, the MGCP connection will be lost while the phone keeps
ringing. When the other end finally picks up, the call gets
disconnected.
This behavior is odd and requires a proper fix. For now increasing the
timeout to 120sec. will decrese the probability that he problem occurs.
- Increas RAN timeout to 120sec (2 min).
