Hello all, We got a complain from someone getting a distorted audio while he was recording a message. He was connected to a PJSIP voice mail client, which was first playing a welcome prompt, then a beep before starting the recording. While he was recording his message. he heard distorted audio back in the stream from PJSIP towards his VoIP-client (while this should be silence). He included the attached rtpstream.pcap (only RTP-stream, not SIP-signalling) My investigation so far: - The VM-client is using PJSUA as UA over PJSIP/Media - In PJSIP we have VAD is disabled (no_vad = PJ_TRUE) - The media negotiation was about G.711-aLaw 40ms (using ptime attribute). (G.711-40ms will give 320 bytes payload) - The PJSIP-client uses IP=192.168.12.129 Till packet #475 the welcome prompt is being played. At that moment the player is destroyed and a tone-generator for the "beep" prior recording is set in place. We can see that from packet #477-587 (where the tone-gen is not active yet) there is still a 40ms packet stream, but now with 80 bytes 0xD5 silence packets (while I would expect 320 bytes). At packet #587-#602 the "beep" prior recording is transmitted. Here we see 320 bytes payload again (OK). After the beep, the tone-gen is destroyed and the wav_recorder is started. >From that moment (#604) we see again 80 bytes silence iso 320 bytes. Can anyone point me where to fix this?
