I´m trying to change the sender number, It should depends on who ist making the call. At the moment it comes only the DID- number from Sipgate-Trunk.

I have tried to change in the dialplan and in the directory the "Effectiver_caller_id" and the "outbound_caller_id" (Number and Name) without success. 

I also changed in the gateway the "caller-id-in-from" to "true", but with that Parameter, the gateway doesn´t work.
