Abstract

A method and system for providing call forwarding in an IP telephone network is disclosed. First, when a telephone number for a first telephone from a second telephone is dialed, the call is routing to a call manager. Call setup procedures with a BRG responsible for the first telephone are then initiated. The BRG then checks stored call forwarding profiles to determine whether there is an active call forwarding profile for the first telephone. The call is connected to the first telephone if an active call forwarding profile is not found. However, if an active call forwarding profile is found, the call forwarding information is sent to the call manager. The call is routed to at least a third telephone based on the call forwarding information.

Claims

the customer premises equipment determining whether call forwarding features are active;

the customer premises equipment retrieving the call forwarding profile specifying the call forwarding parameters for the first telephone number, in response to determining forwarding features are active;

the customer premises equipment determining by checking the call forwarding profile, whether the forwarding parameters are satisfied; and

the customer premises equipment sending to the network device a second data message comprising a new call destination number for rerouting of the call to a third telephone in response to determining the call forwarding parameters are satisfied.

2. The method of claim 1, wherein the call forwarding parameters includes multiple unique identifiers to which the call can be routed.

3. The method of claim 1, wherein the call forwarding parameters specify that only calls from a predetermined list of caller identifiers are to be forwarded.
