Sayyad Nikhat Parveen, Prof. Tirupati M. Goskula
An Internet Protocol Based Private Branch Exchange System consists of one or more SIP (Session Initiation Protocol) phones. The IP PBX server functions in a similar manner to a proxy server: SIP clients, being soft phone or hardware-based phones, register with the IP PBX server, and when user wishes to make a call user ask the IP PBX to establish the connection. The IP PBX has a directory of all phones/users and their corresponding SIPS address and thus is able to connect an internal call. An IP PBX is a complete telephony system that provides telephone calls over IP data networks.
All conversations are sent as data packets over the network. IP PBX can enable each and every employee/person in an organization to be provided with a voice extension, thereby multiplying his/ her productivity. Easier to manage the routine operations because of web/Graphical User Interface based configuration interface. It eliminates phone wiring as it uses existing network. There is no need to disrupt current external communication infrastructure and operations
