I am setting up a new 3CX server internally, and all went well till setting up the trunk; we use OneRing Networks, which is an ATT reseller so I selected ATT, no auth etc, but when making a call it keeps sending the internal 192.168.1.xx address. I do not have stun enabled, instead setting the public IP as static and also attempted to set static within the 'Advanced' section of the trunk. Any idea why this would be happening? I am using v14 sp2. I figured it might be the VIA field but can't change that. I really don't want to have to put this directly on an external ip without using our firewall..
