Abstract
A method and system are disclosed for bypassing a cellular wireless communications system by using a peer-to-peer wireless link for voice communications between BLUETOOTH enabled handsets. In an exemplary embodiment, when a ten-digit telephone number is dialed to place a call from a cellular wireless telephone, the cellular wireless telephone determines whether a termination-point, such as a second cellular wireless telephone, associated with the ten-digit telephone number is within range of the peer-to-peer wireless link. If the termination-point is within range, then a direct intercom session may be established over the peer-to-peer wireless link. Otherwise, a call initiation is requested over the cellular wireless communications system.
