The Route Pattern screen defines the route patterns that the server uses. Each route pattern contains a list of trunk groups that can be used to route the call. The maximum number of route patterns and trunk groups allowed depends on the configuration and the memory that is available on the system.

Use this screen to insert or delete digits so that the system routes AAR or ARS calls over different trunk groups. You can convert an AAR number into an international number, and insert an area code in an AAR number to convert an on-network number to a public network number. Also, when a call directly accesses a local central office (CO), if the long-distance carrier provided by your CO is unavailable, the system can insert the dial access code for an alternative carrier into the digit string.
