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.

Claims

1. A service control point (SCP) method comprising:

receiving a termination attempt query from a terminating switch processing a received call from a calling communication station for a called communication station;

in response to the termination attempt query, determining whether standard caller identification information for the calling communication station can be provided to the called communication station; and

if standard caller identification information can be provided, transmitting from the SCP to the switch a forward call message which includes an identifier for the called communication station and a presentation indicator set to presentation allowed, the forward call message arranged to cause the switch to initiate a call between the calling communication station and network equipment for the network equipment to prompt the calling communication station for audible caller identification information to be provided to the called communication station with call completion options.

2. The SCP method of claim 1 further comprising:

detecting a Calling Party Identifier in the termination attempt query;

placing the Calling Party Identifier in the forward call message as the identifier for the called communication station; and

setting a presentation indicator for the Calling Party Identifier to presentation allowed.

3. The SCP method of claim 1 further comprising:

detecting the presentation indicator for the calling communication station in the termination attempt query; and

if the presentation indicator is set to presentation restricted, determining that the standard caller identification can not be provided.

4. The SCP method of claim 1 further comprising:

detecting a Called Party Identifier in the termination attempt query;

placing the Called Party Identifier in the forward call message as a Redirecting Party Identifier; and

setting a presentation indicator for the Redirecting Party Identifier to presentation allowed.
