[M] Change in osmo-ttcn3-hacks[master]: msc: detect RTP to CN failure in call tests

by neels

neels has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/31711 ) Change subject: msc: detect RTP to CN failure in call tests ...................................................................... msc: detect RTP to CN failure in call tests When CN RTP is missing, the X2 timer will fire after all other call signalling looks successful. So far we establish an MT call, wait three seconds and directly disconnect, long before X2 or X2427 can fire. Make X2 shorter. (By means of f_vty_config() from ttcn, so that we don't need to edit various osmo-msc.cfg in various repositories. The short timer is always critical for the test to be accurate.) Add proper function to detect premature disconnect. Otherwise we just get a cryptic message like "Couldn't find MnccExpect for incoming call" because of MNCC messaging after the unexpected release event.

[M] Change in osmo-msc[master]: [codecs filter] use filter result in MT DTAP CC Setup

by neels

[M] Change in osmo-msc[master]: in ran_msg, return gsm0808_speech_codec (intra-MSC)

by neels

neels has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-msc/+/31695 ) Change subject: in ran_msg, return gsm0808_speech_codec (intra-MSC) ...................................................................... in ran_msg, return gsm0808_speech_codec (intra-MSC) Do not convert to enum mgcp_codecs, but directly pass the gsm0808_speech_codec IE from the A interface to codecs handling. For Iu: - RAN side: use ran_infra.force_mgw_codecs_to_ran to keep the MGW endpoint towards RAN on IUFP. - CN side: introduce flag ran_msg.assignment_complete.codec_with_iuup, so to decide whether to forward IUFP towards CN, we don't need to test the RAN type, but use the flag from the ran_msg implementation. In msc_vlr_tests, use the SDP codec string instead of enum mgcp_codecs. So far limit to intra-MSC related messaging, adjusting inter-MSC handover follows in a separate patch.
