As I stare at my traces I'm seeing an issue with sipxbridge via headers. The PBX is behind a NAT and has it configured. Calls to the SIP trunk for external calls are fine.
The gateway that is configured between the PBX and the SeimensPBX are not separated by nat. The IP address is separated by only a few digits. The gateway is set to NOT use the public ip for call setup. However, the via header from sipxbridge to the siemens has the public ip in the VIA header. Then when the 200ok comes back the seiemens appends a "received=privateip" to the via. I've confirmed the local subnets are correct. I even removed them all and out in the entire 10.0.0.0/8. Same problem. Any thoughts on why sipxbridge is throwing the public ip in the via? I suspect this might be my issue with the transfer as sipxbridge should be using the via header to validate the response right? -M
