Routing Table
Figure 22 below shows how this information enters the Routing Table control.
Figure 22. VoIP to TDM calls
The Routing Table configuration will determine what calling and called numbers are sent to the
TDM device, as well as the physical TDM destination.
5.1.2 TDM to VoIP Calls
Calls originating from the TDM interface have a physical source, along with Calling Number,
Calling Name, Called Number, Called Name, Redirect Number, and Redirect Name information.
The Routing Table uses a combination of the physical source, Calling Number, Calling Name,
Called Number, Called Name, Redirect Number, and Redirect Name to determine the URL of the
destination call. Take the case where a call occurs as follows on a T1 interface:
Physical Source: Interface 2, Channel 6
Calling Number: 5402
Called Number: 95551212
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 23 below shows how this information enters the Routing Table control.
