I have two FreePBX systems connected via an IAX trunk, and everything is working fine except for one issue. When a call is made from FreePBX 1 to FreePBX 2, the caller ID (CID) displayed is the trunk CID rather than the actual extension that is making the call.
Does anyone know how I can configure this so that the caller ID shows the extension that is calling instead of the trunk CID? Any help would be greatly appreciated!
