  • MULTI-NETWORK TELEPHONE CONNECTIONS
    Publication number: 20110026468
    Abstract: The subject matter of this specification can be implemented in, among other things, a computer-implemented method for centralized routing of voice communication over multiple communication networks including receiving at an electronic call routing system an incoming call from a calling device to a first telephone number of a mobile device. The method further includes selecting a calling address of the mobile device from among a voice over internet protocol address of the mobile device on an internet protocol network and a cellular telephone number of the mobile device on a cellular telephone network. The first telephone number is different than the cellular telephone number and the selection of the calling address is performed substantially without participation by the cellular telephone network. The method further includes connecting the incoming call to the selected calling address of the mobile device.
