Hi All I am struggling to find a way to stop codec lock step pjsip follows if it receives more than one codec in the SDP answer from the remote end. I tried changing the pjsua_call.c line no. 35, changing LOCK_CODEC_MAX_RETRY to 0 and it does change the behavior but then my application crashes with following assert failing: File: wav_player.c , line no. 574 - pj_assert(fport->fmt_tag == PJMEDIA_WAVE_FMT_TAG_ULAW || fport->fmt_tag == PJMEDIA_WAVE_FMT_TAG_ALAW); This was not happening if I had not made the change for disabling the codec lock code. Please help me disable the codec lock code cleanly. Best Regards Vikas Gupta -------------- next part -------------- An HTML attachment was scrubbed...
