Abstract

A call manager includes a device process that controls a first device and that receives a call request from the first device. The call request includes a telephone number associated with a second device that is controlled by a second call manager. The call manager also includes a digit analysis module that determines device location information associated with the telephone number included in the call request. Furthermore, the call manager includes a call control module operable to receive the device location information from the digit analysis module and to communicate the call request to the second call manager identified by the device location information.
