Abstract
Abstract A method and apparatus for routing an incoming telephone call to an individual in a building who is not in his or her office. The individual carries a wireless communications unit, typically incorporated in a clip-on badge, that receives messages and transmits both responses and periodic signals to allow tracking the location of the individual. When a call arrives, a message indicating the call is transmitted to the communications unit, which displays an indication of the call together with responses that can be selected to determine how the call is to be routed. Such responses include, in particular, locations of telephone instruments near the individual that the call can be routed to. If the individual selects a particular location, the response is transmitted back to a PBX to cause the appropriate routing.
