5.1 Routing Table Overview
The Routing Table (previously referred to as the Dial Plan) describes a set of rules used to define
the characteristics of a call routed through the gateway. It allows telephony requests to be processed
if the inbound information is matched against configured set of rules and determines if there is an
available outbound route for the request. The primary characteristics include the destination
address and the CPID (call party identification) information. The Routing Table 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
Routing Table 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: 8675309@172.16.3.200
The user at address 172.16.3.131 is attempting to connect to the gateway at 172.16.3.200. The
calling number is 101, and the called number is 8675309.
