Hi, When using the SILK codec, I am only getting one way audio: rtp.c pjmedia_rtp_session_init: ses=0x9bdc55c, default_pt=104, ssrc=0x55d47fd9 rtp.c pjmedia_rtp_session_init: ses=0x9bdc8a0, default_pt=121, ssrc=0x55d47fd9 It looks like pjmedia is changing the payload type causing a mismatch at the server. Is there a way to determine what is causing the payload type to change from 104 to 121? Thanks in advance, Alex. -------------- next part -------------- An HTML attachment was scrubbed...
