Hi. I'm trying to use Pjsua with TCP with the following commands: ./pjsua-i686-pc-linux-gnu --ip-addr=60.2.1.100 --null-audio --log-file=mylog.log --log-level=6 --outbound=sip:60.101.201.1:5060 --no-udp >>> m >>>sip:60.2.10.100:5061;transport=TCP And I get this error message: 12:44:46.658 pjsua_call.c Making call with acc #0 to sip:60.2.10.100:5061;transport=TCP 12:44:46.658 pjsua_call.c Unable to generate Contact header: Unsupported transport (PJSIP_EUNSUPTRANSPORT) [status=171060] Do you know what should I do differently?
