Making Connections in an Application
An application makes and breaks connections as a call
progresses. For example, the following illustrations show an
incoming call to an automated attendant.
First, the T1 board receives a call, as shown in Figure 35.

Next, the T1 board connects the incoming call to a resource on a
Vantage VPS board assigned to use stream 6, as shown in
Figure 36. The application directs the voice resource to play a
recorded message requesting an extension number.
