Maybe you should ask them how to do this! Maybe you should add a
Diversion header, maybe they don't allow this kind of spoofing at all.
This is a common request from users of SIP trunks and your use case is
legit. If Callcentric does checks on callerid validity and there is a
call to a customer with callerid X, they should be able to use this
callerid X when forwarding to an external device/number.
