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.
