When you select or change a PRI protocol, the Service Type and Service ID fields automatically
clear for each entry in the routing table for that PRI.
PRI routing protocols
Table 56 lists the service/DN type choices available for PRI lines.
Using destination codes
Destination codes allow you to control how the system interprets and routes dial strings from
internal sources. Destination codes are similar to line pool codes except that by using routes
(which attach dial strings and DN type designators to line pools) and schedules you can control
what digits the user has to dial and how the system routes the call out of the system, including what
numbers from the dial string get added or deleted to the route dialout.
