I setup an inbound route of +6191111111 and assigned it to the extension, so it had this bogus one and the real DID, then I checked marked the +6191111111 to be the outgoing CID (you have to do this is a certain order to get the +6191111111 VS the real DID to show up as checkable, a flaw I think)
There needs to be some better options for setting outbound caller ID. This was easy in FREEPBX/Asterisk.
