Hi, I have a seemingly very simple configuration with SipX 4.0 (sipxbridge activated), an authenticated SIP trunk and a firewall. IP addresses are the following (not actual addresses): 1.2.3.4: IP address of the SipX box, also hosting sipxbridge 1.2.3.40: A SIP endpoint on the internal network, same domain as 1.2.3.4. 10.20.30.40: Public IP address of the SipX box, on the other side of the firewall. 40.30.20.10: Address of the SIP trunk
Now there is an INVITE initiated at 1.2.3.40, going through 1.2.3.4 and to the trunk. Excerpt from the sipxbridge log (debug, message log at the end of the mail). The c= line in SDP is correctly set to 1.2.3.40. Sipxbridge bridges the request. The outgoing request (message log at the end of the mail), however, has c= line with the address of 1.2.3.4. What is even more surprising is that the call works but in some scenarios, I have problems with the media. Shouldn't c= be 10.20.30.40? How to configure sipxbridge so that the public IP address is sent in SDP? I am not aware of any additional SBCs, just the firewall.
