Zusammenfassung:	PURPOSE: A call routing method based on session initiation protocol presence information and the architecture are provided to comprise a call routing rule using a high customized method which guarantees the communication with a receiver through a telephone. CONSTITUTION: An environment(10) managing a process comprises a server(12) performing the process. The server includes a computing device. The computing device comprises a presence server(40) performing a service and a feature server(50). The presence server and the feature server correspond to one or more computing module on the same or different computing architecture. A receiver sets a profile at the feature server. The profile includes call routing information of the receiver based on the presence information of the receiver. The presence server is updated using the position information of the receiver. A subscription function is provided to the presence server using an SIP subscription message.
