TDM to VoIP Calls

Calls originating from the TDM interface have a physical source, along with calling, called, and
redirect number information. The dial plan uses a combination of the physical source, calling,
called, and redirect numbers to determine the URL of the destination call. Take the case where a
call occurs as follows on a T1 interface:
Physical Source:
Calling Number:
Called Number:
A call is being received on the 6th channel of physical interface 2. The calling number (the caller)
is 5402, and the number called (dialed) is 95551212. Figure 17 below shows how this information
enters the dial plan control.

Calling Number: 5402
Called Number: 95551212
TDM interface: 2; Channel:6
The dial plan configuration will determine the calling number, called number, redirect number, and
VoIP address of the destination call. However, only the calling and called numbers can be used to
route the call (i.e. the redirect number is not considered for routing purposes).
