Changing Caller ID with off-net routing to cell phones

Is it possible to change the caller ID of an inbound call to static number when forwarding the call off-net to a cell phone? Here's what we have set up:

The caller calls a Toll Free number that is routed to our SM and then is routed to an internal VDN on our core. The VDN is sent to a vector with an auto-attendant with options (press 1 for X, press 2 for Y, etc). Some of the calls are routed off-net to an external cell phone. When this happens, the originating caller ID shows on the cell phones but our management wants to have another static number show as the ID so the cell phone users can program the numbers to identify as business calls (some of these users are after hours reps). We use SIP for trunking and I have not been able to find a solution for this, which is why I'm reaching out today.
We have tried routing the calls to stations with call forwarding active, we have tried routing between VDNs but nothing worked. Any suggestions?
Thank you

Is the SIP trunk terminated to an Avaya SBC-E? If so, use a SigMa script to perform this manipulation. I wrote the attached example for you. This inspects the To header and if there's a match on 2125551111, the From and P-Asserted-Identity headers are changed to static CID 2125552222.

Replace the destination and source numbers as needed. Apply the script to the SIP server in the SBC-E configuration representing the service provider. If multiple manipulations are needed, the "if" statement code blocks can be repeated. They will be checked in order. Hope this solves your problem.
