We have a SIP service using C2851 GW with CUBE. Our outbound calls to the provider must have external mask of our DID range ex 999888XXXX.
Problem when turning on forward to outside number - is that the calling number is used and the provider rejects the call. Ex - Caller from 1112223333 to 9998887777 - phone forwards call back out to SIP provider using 1112223333@1.1.1.1 - call is rejected.
Not sure where to tell CM or the GW to use the called number instead of the calling number when forwarding calls.
Help greatly appreciated.

Under SIP Trunk we have a configuration for option for Calling number
Calling Party Selection By default is set to Originator change it to First Redirect Number.
