Abstract
A method for managing geographical information of a plurality of Voice over Internet Protocol (VoIP) terminal devices using a VoIP server receives location information of the VoIP terminal devices from the VoIP terminal devices, stores geographical information of the VoIP terminal devices into a data sheet stored in a storage device of the VoIP server. The method detects a query from one of the VoIP terminal devices, retrieves the geographical information from the data sheet according to the query, and obtains an electronic map from the storage device. The method further populates the retrieved geographical information on the electronic map, and sends the electronic map to the VoIP terminal device corresponding to the location information.
