Oliver Smith 25363b1891 add codec arg
Add codec parameter to start_call() and convenience functions mt_call()
and calls() with FR as default. While at it, update the help text.

Duplicate enum codec_type into, because the enum
values are different from the existing enum values in the python code
(GSM48_BCAP_SV_EFR etc.).

Oliver Smith 0193c914e4 rtpsource: CTRL call rtp_create: add codec arg
Instead of hardcoding FR in rtpsource, add an argument to set the codec
from via CTRL call rtp_create. Hardcode FR in for now, a follow up patch will make it configurable
there, too.

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.

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
