So, when RTP relay is being used it works fine, audio both ways, trace looks normal.
when using lines/TDM bus then this shows in the trace:
203249mS CMMap: PCG::MapBChan pcp[113]b0r1 cp_b 0 other_cp_b 0 type CGTypeSimple
203249mS CMMap: PCGS CPReserveCodec for the other end (pcp[113]b0r1) true
203249mS CMMap: PCG::MapBChan pcp[32]b1r0 cp_b f595176c other_cp_b f595b068 type CGTypeSimple
203249mS CMMap: a=0.18 b=21.42 M1
203249mS CMMap: PlatformConnectionAudioSAP::ConnectVoice (connect) pcp[113]b0r1 echo_cancellation set to 0
203250mS CMMap: PlatformConnectionAudioSAP::ConnectVoice pcp[113]b0r1 Configure 0.18
203250mS CMMap: PlatformConnectionAudioSAP::ConnectVoice pcp[113]b0r1 ConnectIndication 0.18
203250mS CMMap: a=0.18 b=21.42 CheckSpeechPathMonitor (pcp[32]b1r0) register
203250mS PRN: Confer DSP, channel 0: allocated DTMF detector 0, 23 free
And that is what causes the audio issue, the packets go in/out on the same RTP ports and all arrive at the handset but it just plays silence.....well done Avaya, you did it again
