dicko. Posting this in new thread. You helped me with a custom extension. Works great. Is there a way to pass a defined caller ID? The ID being passed is of the calling party, and not the Outbound CID of the Extension. The receiver wants to know it is a call from this Extension. I don't want to turn Call Screening on. Putting xxx in the CID Prefix on the Inbound Route does not work. Thanks.
