An application requires that all calls that originate from Port 1 of the Dual
T1/PRI Module in Slot 1 be switched to Port 2 of that same module. Assign
a unique Source ID (e.g. 7) to Port 1 ofthe module, andthen configure Port
2 to only accept calls from that unique Source ID (7).
The Caller ID number must be specific (i.e., no “wild cards”).
