40 IP Media Server (Global Call) Demo Guide — August 2005

Demo Details

The threads are created as follows:

1. The first (main) thread is created by the demo application to get the keyboard input.

2. The second thread is an SRL thread, created as a result of the demo application calling

PDLsr_enblhdlr( ). All Global Call events are received through the SRL.

5.4 Initialization

This section describes the IP Media Server (Global Call) demo initialization as shown in Figure 5.

A system is started in the following sequence:

1. The application creates CConfig( ) to parse the configuration file.

2. The application creates CEventRouter( ) to start the Event Router, which, in turn, starts the IP

module and the Voice module. When a module is started, it initializes its boards, devices and

state machines.

After all the modules are started, the EventRouter starts to build a static routing table that maps

voice devices to IP devices. It is important that each IP device has a dedicated voice resource, so

that when an IP channel is connected (an incoming call is answered) the user can get a voice

prompt immediately.

If the initialization should fails, the application shuts down. The shutdown sequence is the reverse

of the initialization sequence.
