Abstract
A voice over IP (VOIP) network 8 includes a graphical proxy server 34 that allows “dumb” terminals (32) to act as SIP phones or H.323 phones; only the graphical proxy server (34) needs to support the underlying signaling protocol. The graphical proxy server (34) includes a graphical server (40) and a terminal management system (42). The terminal management system (42) handles the calls for each associated graphical terminal (32) and interacts with the graphical server (40) to provide a customized GUI for each graphical terminal (32) to display current call status. Each terminal (32) has a respective instance of a terminal controller program (56) in the terminal management system (42). The terminal controller for a terminal (32) controls the terminal's GUI responsive to incoming SIP messages directed to the terminal and generates SIP messages responsive to user interaction with the terminal's GUI.
