DDI Operation.

The XN120 will can also route DDI numbers. This allows calls to be presented to individual extensions (desk-

to-desk dialing). This is the most common method of handling incoming SIP calls.

With DDI operation the network will pass the last digits of the dialed number to the XN120. The XN120 then

compares these digits to a look up table, if the number matches any entry in the look up table it will follow the

routing specified.

In brief,

Set each VOIPU line as DDI mode in Program 22-02-01, ensure you do this for all night modes.

You then place the lines into Trunk Groups in Program 14-05-01, route each Trunk Group to an area within

the DDI table in Program 22-13-01.

Then enter all DDI numbers in the area specified with their associated destination in Program 22-11-01.
