When calling pjsua_call_hangup_all(), I get the following in my console: 09:43:40.306 tsx0x7812264 Failed to send Request msg BYE/cseq=25051 (tdta0x7848600)! err=171060 (Unsupported transport (PJSIP_EUNSUPTRANSPORT)) 2010-10-25 09:43:40.306 Test[689:207] Call 0 state=DISCONNCTD 09:43:40.306 pjsua_media.c Media session for call 0 is destroyed 09:43:40.306 icetp00 Stopping ICE, reason=media stop requested 09:43:40.307 pjsua_call.c Failed to send end session message: Unsupported transport (PJSIP_EUNSUPTRANSPORT) [status=171060] Everything works as far as making/receiving calls, and a packet sniffer revealed that if the called party hangs up, the BYE message is sent and received as it should be, but my app isn't sending anything out SIP-wise when I call pjsua_call_hangup_all , just "Goodbye" over RTCP. Any ideas as to what might be causing pjsua_call_hangup_all() to fail? -------------- next part -------------- An HTML attachment was scrubbed...
