Abstract
A system (100) and method deliver audible caller identification information when standard Caller ID information can not be provided, even when a subscriber to the service has per line blocking. A service control point (106) detects the directory number to which a terminating attempt trigger is assigned and places this directory number in a parameter for transmission to a service switching point (102) using a forward_call message (206). The per line blocking function does not interfere with transmission of this parameter so that the called party's directory number can be passed for processing and call completion by the system.
