Patent ID: 8855107

Claim:
A method of processing calls, the method comprising: receiving over a network at a call processing system operated by a first service provider a first call from a caller directed to a first phone address of a user, wherein the user receives wireless service from a wireless provider, and wherein signaling information associated with the first call includes the phone address of the caller and the first service provider is different than the wireless provider of the user; originating a second call from the call processing system to a mobile device of the user, wherein the mobile device accesses wireless service provided by the wireless provider of the user; determining if the mobile device of the user is unavailable by detecting a voice prompt provided by the wireless provider of the user and without accessing a Home Location Register system of the user's wireless provider, wherein the caller does not hear the user unavailable voice prompt; querying a call processing system database to determine an alternate phone address associated with the user; originating a third call from the call processing system to the alternate phone address associated with the user, wherein signaling information associated with the third call includes an identifier associated with the caller so that the third call appears to be originating from the caller; and, bridging the first call with the third call.
