Is there a way to mask the extensions that are shown on a phone recieving a call from an internal number? For example: Phone A has extension 4000 and from this extension phone A dials phone B. Phone B will see that the call is coming from 4000. Is there a way to easily change this?
You may give it a shot with the translation patterns. I am not sure if it work for calls between IP phones on the same cluster though, also the callerid restriction option in the transformation option is for outgoing calls only i guess.
