Harald Welte 6ecdaf6c01 mncc_mt_loadgen: Don't call GsmCallFsm() with rtp_bridge=True
rtp_bridge=True triggers the automatic transmission of a MNCC_RTP_CREATE
when that call goes into ACTIVE state.  We don't want this in the
case of mncc_mt_loadgen, as we perform this at a much sooner point in

Harald Welte 41af37de9f Program for MT call load testing with rtpsource
This program (derived from is used to start MT calls
via the MNCC interface of OsmoMSC.  Every calls RTP is connected
to the new 'rtpsource' process, which generates a realistic RTP
flow in terms of number of packets (20ms interval) and payload size.

Harald Welte 09462c3b04 initial checkin of 'osmo-rtpsource' program
osmo-rtpsource is a small utility program which is generating
RTP flows at a constant rate of 20ms, as required in most IP based
telphony.  The payload currently is hard-coded.

that at start and check for availability of the reqquired
executable programs (part of python-ctypeslib).

Vadim Yanitskiy a275d7a49d *.py: cosmetic: tweak the global logging format
Printing log level, file name, and line number together with a
log message is the common practice in Osmocom projects that
facilitates debugging and development.

Vadim Yanitskiy 1e3f0aaf6b throw / raise exceptions from MnccSocket
Calling sys.exit() from MnccSocket's constructor could lead to
a situation when the main thread becomes "dead", while its child
threads are still working. Let's throw the exceptions towards
the caller, so it would be possible to handle them there.

Gerard Pinto 983231a70d Bearer capability not provided during MO call using mncc-python, which results in GSM IE error (96) invalid mandatory information sent by Network -> MS (mncc-python)
Verified this error by GSMTAP using mncc-python interface OsmocomBB to network
Proposed Changes:
In case of MO call (_onmncc_setup_req) caller needs to provide bearer_cap speech version
Added mncc.bearer_cap in based on codecs = GSM48.AllCodecs
Added new field mncc.MNCC_F_BEARER_CAP in mncc.MNCC_SETUP_REQ, when call is initiated (MO) from MS -> network

Holger Hans Peter Freyther ce184f83f0 test: Add a manual test to simulate DTMF handling in osmo-sip-connector
Add a manul test to the contrib folder that helped and can help during
the development of osmo-sip-connector or similar software. This avoids
having to create a separate mncc module.

It can be started like:

$ PYTHONPATH=$PWD/../ python

share code between client/server.
