Hi Samuel, Once again, thank you so much for your gr8 work! I fixed the the issues with the audio-dev, and now my audio device can be found. I don't get that error anymore, but a new problem came out... the app now crashes when trying to make a call, or to receive one: "Assertion failed: (b && frame), function pjmedia_delay_buf_get, file ../src/pjmedia/delaybuf.c, line 317." This is the log from an incoming call: 04:18:14.677 pjsua_media.c Opening sound device PCM at 16000/1/20ms 04:18:14.725 ec0x243640 Echo suppressor created, clock_rate=16000, channel=1, samples per frame=320, tail length=200 ms, latency=2 ms 04:18:15.031 conference.c Port 2 (ring) transmitting to port 0 (IPHONE) 04:18:15.038 pjsua_client.c Incoming call for account 2!

Do you know what might be the problem? Regards, Maya -------------- next part -------------- An HTML attachment was scrubbed...
