I am on this for months now, can't understand why pjsua_app.c (sample never got compiled segmentation fault). My test code, I can register and call receive without voice/sound, never ever yet hear how pjSUA sounds. 1. Code sample: http://gist.github.com/559012 2. Scenario: http://i.imgur.com/D0hec.png Problem: When i make a call it gets failed with following cause: 15:33:55.738 tsx0x93b2664 State changed from Null to Calling, event=TX_MSG 15:33:55.738 pjsua_acc.c Registration sent * 15:33:55.738 pjsua_media.c Error retrieving default audio device parameters: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [status=420006] 15:33:55.738 APP Error making call: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [status=420006]* 15:33:55.738 pjsua_core.c Shutting down... 15:33:55.738 pjsua_pres.c Shutting down presence.. 15:33:55.738 pjsua_media.c Shutting down media.. 15:33:56.210 pa_dev.c PortAudio sound library shutting down.. 15:33:56.211 endpoint Request msg REGISTER/cseq=26593 (tdta0x939c150) created. 15:33:56.211 sip_reg.c Unable to send request, regc has another transaction pending Thank you -------------- next part -------------- An HTML attachment was scrubbed...
