Programming Model
This section describes the IP Media Server (Global Call) demo architecture. It contains the 
following topics:
5.2.1
Module Structure
The IP Media Server (Global Call) demo uses a modular architecture, in which each technology 
(IP, voice, CSP) is wrapped inside a module so that a particular technology can be easily added or 
removed. 
The system contains two modules:
IP module that serves as the front end to communicate with the IP network
Voice module to provide voice service
The system also contains a software component, the EventRouter, to connect the modules. The 
basic architecture of the system is illustrated in Figure 2.
