Hi Chris, ok, in this case it seems to be related with your special audio-configuration. Some experiments with the build might help here. On some Ubuntu-systems for example, I had to compile without the included portaudio-implementation due to some conflicts between this portaudio-impl & pulseaudio. Therefore I had to insert the following lines into the file pjlib/include/pj/config_site.h #define PJMEDIA_AUDIO_DEV_HAS_PORTAUDIO 0 #define PJMEDIA_AUDIO_DEV_HAS_ALSA 1 furthermore you may want to disable all unnecessary options (see ./configure --help) in the build-configuration. Watch out for these *config*.h where You can also find several hidden switches. But before trying out lots and lots of configurations, You can try a few tests, to narrow down the cause: - run a testprogram, that uses the PJSUA-ToneGenerator - do you hear these local generated tones? - make a call and measure the RTP-traffic with wireshark: is there any data transmitted? Empty (silent) audio-packets? Or nothing (no packets)? Greetings Niels Klaas > Thanks Niels. > > I'm running on an Arm based system running a Debian variant.?
