Abstract
A system and method deliver audible caller identification information when standard Caller ID information is invalid or can not be provided, even when the called party connects to the network by private trunk group facilities. In one disclosed embodiment, a trunk group trigger associated with the called communication station is encountered, launching a termination attempt query. If standard caller identification information can not be provided for the calling party, the call will be routed to a privacy service to obtain the audible caller identification information.
