Hi Herbert, The Master/sound underflows are indicative of a problem. You'd expect these if CPU is exhausted, but since the AEC is off pjsip is using negligible CPU. Perhaps try to increase the number of audio buffers in ALSA driver? Also in order to play a file to audio device using pjsua, you need to specify WAV file using --play-file and then manually connect the WAV file port to sound port using cc command.
