Patent ID: 8843582

Claim:
A machine-readable storage device comprising instructions which, responsive to being executed by a processor, cause the processor to perform operations comprising: searching a phone number in a phonebook of a mobile communication device responsive to a request to initiate a mobile originated call from the mobile communication device; if the phone number cannot be found in the phonebook of the mobile communication device: scanning for a wireless local communication device comprising a phonebook; detecting, when available, the local communication device; responsive to succeeding in the detecting of the local communication device: searching for the phone number in the phonebook of the local communication device; responsive to finding the phone number in the local communication device, retrieving the phone number from the local communication device responsive to a selection and initiating a mobile originated call corresponding to the phone number without storing the phone number in the phonebook of the mobile communication device; and responsive in failing to find the phone number in the local communication device, requesting service from a phonebook directory proxy server; responsive to failing in the detecting of the local communication device, requesting service from the phonebook directory proxy server; and retrieving the phone number from the phonebook directory proxy server; transmitting details, including a caller identification of the mobile communication device and an enterprise identification of the mobile communication device, to establish connectivity with a terminal device corresponding to the phone number, wherein transmitting the details causes the phonebook directory proxy server to determine if the enterprise identification of the mobile communication device is an abbreviated-length phone number, and responsive to the caller identification being the abbreviated-length phone number, retrieving a full-length network identification comprising a full-length phone number corresponding to the abbreviated-length phone number as the enterprise identification; wherein transmitting the details causes the phonebook proxy server to replace the caller identification of the mobile communication device with a corresponding caller identification that emulates the enterprise identification as if the mobile originated call originated from within the enterprise when the mobile communication device is not located within a vicinity of the enterprise, to transmit a first network originated call to the terminal device over a first voice channel, to transmit a second network originated call to the mobile communication device over a second voice channel, and to link the first and second voice channels, wherein the first network originated call is over a packet-switched network, and wherein the second network originated call is over a circuit-switched network.
