Hi! I experienced that pjsua-API and with IPv6 as transport does only work if I specify an outbound proxy with IP address. No outbound proxy or outbound proxy with domain (instead of IP) does not work. I also had the same problems when using the pjsua client. Is this a known issue or am I doing something wrong? The error in pjsua: 13:40:56.406 pjsua_core.c SIP UDP socket reachable at ::1:5060 13:40:56.406 udpv600D29340 SIP UDP IPv6 transport started, published address is [::1]:5060 13:40:56.406 pjsua_acc.c Account <sip:[::1]:5060> added with id 0 13:40:56.406 pjsua_acc.c Account sip:klaus.darilion@[sip.labs.nic.at] added with id 1 13:40:56.406 pjsua_acc.c Unable to generate suitable Contact header for registration: Unsupported transport (PJSIP_EUNSUPTRANSPORT) [status=171060] 13:40:56.406 pjsua_acc.c Unable to create registration: Unsupported transport (PJSIP_EUNSUPTRANSPORT) [status=171060] The error in my application (QjSimple): 13:42:18.078 pjsua_media.c RTCP socket reachable at 10.10.0.198:4007 13:42:18.078 pjsua_acc.c Account sip:klaus.darilion at sip.labs.nic.at added with id 0 13:42:18.078 sip_reg.c Invalid Contact URI: "<sip:klaus.darilion@::1:1190>" 13:42:18.078 pjsua_acc.c Client registration initialization error: Invalid URI (PJSIP_EINVALIDURI) [status=171039] 13:42:18.078 pjsua_acc.c Unable to create registration: Invalid URI (PJSIP_EINVALIDURI) [status=171039] thanks Klaus
