Hello Everyone, I am using pjproject-2.0 on redhat linux. I have scripts through which i invoke pjsip to test my call flows. Now i am trying to make basic call over IPv6. I had enabled PJ_HAS_IPV6, changed transport type to PJSIP_TRANSPORT_UDP6 in pjsua_transport_create() when pjsua bound to given IPv6 address failed and then was able to register successfully. But when i try to make call, i could see that media bind to ipv6 address fails with below error. 16:35:15.951 pjsua_media.c ..Unable to resolve transport bind address: gethostbyname() has returned error (PJ_ERESOLVE) [status=70018] 16:35:15.951 pjsua_media.c ..Unable to create RTP/RTCP socket: gethostbyname() has returned error (PJ_ERESOLVE) [status=70018] 16:35:15.951 pjsua_media.c ..Error creating media transport: gethostbyname() has returned error (PJ_ERESOLVE) 16:35:15.951 pjsua_call.c .Error initializing media channel: gethostbyname() has returned error (PJ_ERESOLVE) [status=70018] I did go through other email chains which has similar issues but none could resolve my issue. Could anyone throw light on where i should be looking? Thanks, Dhar. -------------- next part -------------- An HTML attachment was scrubbed...
