Hi! Our carrier requires that all calls originating from us have a "from" address that corresponds to one of our DID numbers (e.g. From: email@example.com). Our Sip server (SipX, not 3CX) is configured so that each account sends the correct caller-ID ("from" address) when using a hardware phone or the X-Lite software phone. However calls from the 3CX phone always have the extension or log-in Id as the from address. Changing the caller ID in the 3CX phones configuration changes the text part of the "from" field, but not the actual address. For example making the caller ID 5135952015 results in [From "5135952015" firstname.lastname@example.org]. This still results in outbound calls being refused by our carrier. Internal calls work fine. Does anyone know how to change the actual address used by the 3CX phone or how to make it use the server-configured address? It is otherwise quite a slick phone and I would like to use it. regards, Alan.
