A smart space, such as smart sensor rooms, an office, or simply an area, requires a smart telephony network for an effective voice communication between users. Now-a-days, modern Private Branch eXchange (PBX) system does not only provide telephone exchange, but also supports many heterogeneous telephony networks and provides many other useful functions as well. Despite its powerfulness, PBX still cannot achieve a basic requirement for a smart space: it cannot adapt its surroundings automatically, i.e. people still need to make the call forwarding setting manually. In this paper, the authors propose a system with an algorithm named "2D location-aware" for tracking a person in a smart space.
