At the moment, we're simply evaluating whether PJSIP runs okay on the hardware It is possible that a very very bad sound device may issue more than eight consecutive rec_cb () / play_cb () calls, which in this case it would be necessary to enlarge the RX_BUF_COUNT The Audio Conference Bridge ¶ The conference bridge provides a simple but yet powerful concept to manage audio flow between the audio medias. Through some helpful tips and hints from the Raspberry Audio Troubleshooting How to record audio with pjsua Audio is breaking up Audio drop-outs or “stutters” High jitter value observed by remote party Loud static noise No audio is heard in local speaker No Also unlike in audio call where port connections between audio device and call audio media needs to be set up manually by application, in video, the port connections in the conference bridge are set up These audio capabilities indicates what features are supported by the underlying audio device implementation. Is there some property that I need to set up in pjsip (pjsua) or in AudioToolbox library to enable a sound be played during a sip call? I know this is possible (Bria has this, Groundwire also, I am trying to obtain an audio stream from call audio media to be able to send it to Speech-to-Text engine (to transcribe audio from streaming input). 722 G. Applications get these capabilities in the pjmedia_aud_dev_info structure. I successfully compiled the PJSIP iOS library and registered it successfully. I am getting this error while using pjsip. If no audio is heard with both pjsua and playfile Chances are other apps are unable to play to that sound device Some audio devices such as Nokia/Symbian Audio Proxy Server (APS) and Nokia VoIP Audio Services (VAS) support built-in hardware audio codecs (e.
