Dial Plan Overview

The dial plan describes a set of rules used to define the characteristics of a call routed through the
gateway. The primary characteristics include the destination address and the CPID (call party
identification) information. The dial plan affects calls originating from the VoIP side, and calls
originating from the TDM (T1, E1, analog, etc.) side.
5.1.1

VoIP to TDM Calls

Calls originating from the VoIP interface have two associated URLs. One contains the originating
address and a calling number. The other contains a destination address and a called number. The
dial plan uses this information to determine a final TDM destination for the call. Let's say a call
occurs as follows:
From: 101@172.16.3.131
To:
The user at address 172.16.2.131 is attempting to connect to the gateway at 172.16.3.200. The
calling number is 101, and the called number is 8675309. Figure 16 below shows how this
information enters the dial plan control.
