Abstract
An IP telephony client initiates and manages multimedia sessions. The client includes a user interface, an application interface, and a protocol stack. The application interface provides an interface between the protocol stack and the user interface and helper applications. The protocol stack packages messages received from the application interface and parses messages received from other parties or prospective parties. The application interface converts incoming messages to appropriate application programming interfaces (APIs) and sends incoming payloads to the appropriate helper application.
