Abstract
A system and method deliver audible caller identification information when standard Caller ID information is invalid or can not be provided.

Claims12
A method for processing a call from a calling party at a calling communication station to a called party at a called communication station in a telecommunications network including at least one switch and a telephony database, the method comprising:
- receiving the call from the calling communication station at a switch;
- transmitting a termination attempt query from the switch;
- communicating the termination attempt query to a telephony database,
- wherein the telephony database is configured to:
- determine whether caller identification information contained within in the termination attempt query is valid;
- determine whether standard caller identification information for the calling communication station can be provided to the called communication station;
- identify the call as presentation unavailable, if either the standard caller identification information or the caller identification information is unavailable;
- receiving a forward call message at the switch, when the call is identified as presentation unavailable, wherein the forward call message includes a presentation indicator associated with the called communication station, and a parameter indicating that a selected request message should be used for the request;
- originating a second call at the switch that requests audible caller identification information in accordance with the customer selected request message;
- and
- transmitting, in connection with the second call, the audible caller identification information to the called communication station in a format specified by the called party.
A method for processing a call from a calling party at a calling communication station to a called party at a called communication station in a telecommunications network including at least one switch and a telephony database, the method comprising:
- receiving the call from the calling communication station at a switch;
- transmitting a termination attempt query from the switch;
- communicating the termination attempt query to a telephony database,
- wherein the telephony database is configured to:
- detect in the termination attempt query the caller identification information for the calling communication station;
- determine whether the caller identification information is valid;
- process, if the caller identification information is not valid, the call as if the call is marked presentation unavailable;
- determine whether standard caller identification information for the calling communication station can be provided to the called communication station;
- identify the call as a presentation unavailable call, if the standard caller identification information for the calling communication station cannot be provided;
- receiving a forward call message at the switch for calls identified as presentation unavailable calls, wherein the forward call message includes:
- an identifier associated with the called communication station;
- a presentation indicator associated with the called communication station, the presentation indicator being set to presentation allowed, and
- a parameter indicating that a selected request message should be used for the request;
- originating a second call at the switch, in response to the forward call message, connecting the calling communication station and network equipment;
- transmitting a request for audible caller identification information, from the network equipment, to the calling communication station in accordance with the customer selected request message;
- and
- transmitting the audible caller identification information to the called communication station in a format specified by the called party during the second call.
