HI All, I am unable to Register with my PJSIP softphone behind the NAT and with a port 6000 because I am also in a country where port 5060 is blocked. To use the 5060 port what I do is that I append the port 6000 in the SIP IP like SIPIP: 6000. But no response is coming. But If I use this on eyebeam then it is Registering fine. Please help me in the issue. Thanks in Advance..... Regards: Ravi -------------- next part -------------- An HTML attachment was scrubbed...
