Alcatel Unleashed

I have installed two oxo pcx connected by SIP, one of which is connected to an E1 (local), the other takes IP trunk line for (remote) and performs the external call, but does not show me the number of remote PBX, but the DID header.

I want to know if there are ways that to make the call from the remote PBX, it sends the DID number of his own.

The incoming call if I correctly displays the incoming caller's number.

Send the correct user number from remote OXO so that you can have the correct translation to external number.
