Is there a way to make CallForward from CUCM send the forwarding stations number as the calling number when forwarding calls to a SIP trunk?
Currently, when making external calls, users dial "0" then the number. THis is working fine sending calls to our CUBE gateway.
When users call forward their phones to an external number (local or mobile) if someone dials them from an external location the call fails. Dialling from an internal extension forwards the call as expected to the local/mobile number. I think this means that the CSS/Patritions are set up correctly and the user should be able to forward calls to these numbers.
I think the CUBE dialpeers are causing the issue, which is why i want only forwarded calls to use the redirecting number so I don't have to make many modifications to the dial-peers.
Dubeg ccsip calls on the CUBE when forwarding shows the external calling number as the calling party, so the callforward does return to hit the cube gateway, but fails there.
