A system and corresponding method supports voice communication using a mobile communication device employing a single user associated identification code in different relatively remote locations. A mobile communication device communicates a registration message to an access system at a first remote location using a wireless communication mode responsive to a user registration command via a displayed user interface image. The registration message includes a user associated identification code and security information. The registration message enables the access system to identify the user and to divert voice communication from a first telephone number, linked with a physical address of a second remote location that is associated with the user associated identification code, to the mobile communication device at the first remote location. The mobile communication device receives a response message indicating a status of the diversion of voice communication from the first telephone number linked with the physical address of the second remote location to the mobile communication device at the first remote location.
