#1884 closed defect (fixed)

Audio stutter on remote side after disconnecting stream from microphone in the conference bridge

Reported that in an audio call session, after disconnecting audio flow from microphone to call stream in conference bridge, remote hears audio stutter badly. After investigation, it seems that RTP payload length sent by pjmedia is reduced by half (while RTP timestamp interval stays the same), i.e: audio codec used is PCMU with ptime 20ms, so the RTP payload length is 160 bytes, however after disconnecting the microphone, RTP payload length becomes 80 bytes.

Thanks Marcus Froeschl for the report and analysis.
