I'm using SERP connected to FreePBX, with a Voipfone SIP trunk. When an incoming call event happens, Communication Centre is not showing useful information in the From and To columns. The From column shows voipfone instead of the calling number, and the To column simply shows "s". In Bria, the calling number is shown correctly. Is this something to do with the connection to FreePBX or is there another reason?
