I thought about doing something like that but it would confuse the poor staff :)

They'd have a call from what appeared to be an external number but it would turn out to be an internal extension that was calling them (we generally don't blind transfer).

I need to change the CID on an already-established SIP channel and have no idea if it's doable..
