Hi, I am not sure if I follow all the right steps to setup and initiate a call but it seems that when I make a call that never gets established (dialing to an invalid IP for example) the audio devices are note destroyed. Has anybody seen that ? I did a hack inside pjsua_media_prov_clean_up to call pjsua_aud_stop_stream or pjsua_vid_stop_stream similar to what is done inside stop_media_session. I am not sure if this is the right fix but this seems to address my immediate problem. Emmanuel -------------- next part -------------- An HTML attachment was scrubbed...
