Hello: I am trying to use "pjsua_app.c", but I am not able to speak or listening anything. I debuged the program and when I arrive to if (app_config.capture_dev != PJSUA_INVALID_ID || app_config.playback_dev != PJSUA_INVALID_ID) { status = pjsua_set_snd_dev(app_config.capture_dev, app_config.playback_dev); if (status != PJ_SUCCESS) goto on_error; } it jump to the next option. Is it ok? How can I run the program to set-up a voice conversation. Regards Jorge. -------------- next part -------------- An HTML attachment was scrubbed...
