Hi Vega, At least 2 problems here: 1. assertion on PA callback: pj_assert(frameCount == stream->samples_per_frame * stream->channel_count); This bug has been fixed (see http://trac.pjsip.org/repos/ticket/504). And I have tested with NCHANNELS = 2, it works fine. 2. Assertion `component->hostChannelCount > 0' failed I am not sure about this, please find the similar problem in these discussions: http://techweb.rfa.org/pipermail/portaudio/2005-August/004710.html http://mlblog.osdir.com/audio.portaudio.devel/2005-08/ Currently pjsip is bound to specific revision of PortAudio, so perhaps the problem has been fixed on newest version of PortAudio. nanang On
