Hi All! I need transport parameter to be concatenated to SIP-URI at Contact header of REISTER request sent as PjSUA starts. As I understood from tool's manual, CLI command ./pjsua-i686-pc-linux-gnu --ip-addr=IP-ADDDR --local-port=5060 --null-audio --duration=30 --outbound=sip:IPADDR1 --registrar=sip:IPADDR2:5060--id=sip:1000 at IPADDR --contact=sip:1000 at IPADDR;transport=UDP --contact-params=transport=UDP will cause to PJSUA to send REGISTER request toward registrar through it's outbound defined. The problem is that Contact header of REGISTER request sent, has no transport parameter (transport=UDP) at all. I know that UDP is a default transport but I want it to appear at Contact header. Please advice. Regards, Evgeny Miloslavsky Systest Engineer Juniper Networks Solutions Israel LTD.
