Hi, I did the checklist n?2 "Check that the correct device is being used." by setting the console's log level to 5 with --app-log-level 5 command line argument. Here are the end of messages I got: 15:22:49.986 pjsua_media.c pjsua_set_snd_dev(): attempting to open devices @16000 Hz 15:22:49.991 pasound.c Opened device /dev/dsp(OSS)//dev/dsp(OSS) for recording and playback, sample rate=16000, ch=1, bits=16, 160 samples per frame, input latency=16 ms, output latency=16 ms 15:22:49.991 pasound.c Starting /dev/dsp stream.. Then nothing happens again. I think I should have other messages. I don't know what I omitted to do or what I did wrong. Thanks for your help, C?line NGUYEN -------------- next part -------------- An HTML attachment was scrubbed...
