Hi * I'm wonder: are below errors an pjsip bug or rather issue is on my side? Error is triggered by python app using libpjsip 2.2.1 with kernel 3.15.7 and alsalib/util 1.0.28. Hardware is ION1 with analog audio IN/OUT. My app is working OK except I can't get working local->remote audio. Remote->local works OK. Mic is working - as I can hear Mic in speakers (in fact this audio loop is constant - no mater what libpjsip is doing). Hope somebody answers this post as my previous 3 posts were without any replay... Log for remote calling to local (me)--------------- Media now are opened...
