Hi, I am having an UAC behind NAT. When I send call to openser, openser does NAT traversal & detects external IP & port. As per trace I found that UAC sends request from some internal port and router sends to openser with some other external port. external port is : 50034 internal port is : 5065 So openser sends 183 progress .. to 5065 instead of external port 50034.
Here is the sip trace: U XXX.XXX.XXX.XXX:50034 -> YYY.YYY.YYY.YYY:5060 INVITE sip:to_...@domain SIP/2.0. Via: SIP/2.0/UDP [INTERNAL_IP]:5065;branch=z9hG4bK-a0646ab7.
