Dialing Plan configuration Page 187 of 258
The type of number configured in the NRS should be set to match the type of number as configured in the main office.
Note: If some calls are to be routed differently from others, it is possible to provision the multiple Numbering Plan Entries in the NRS to achieve this.
For example, if ZDP = 101, it is possible to provision multiple Numbering Plan Entries (101, 1011, and so on) to route calls based on the ZDP value or the ZDP value plus some of the dialed digits.
Unlike on the Call Server, if the ZDP plus additional digits are used to identify routing it is not necessary to provision all of the combinations. For example, if calls with digit strings starting with “1011” are to be routed differently from those starting with “101x” (where “x” is a digit other than “1”), then only “101” and “1011” need to be provisioned as numbering plan entries on the NRS.

Procedure 13
Configuring the branch office
1Configure the Route List Index at the branch office.
After the call arrives at the branch office, a route must be provisioned to handle the call. In order to be able to select a trunk to route calls, a Route List Index (RLI) must be configured in the Route List Block (RLB). The RLI uses the route number for PSTN trunk to route calls to the PSTN. A Digit Manipulation Index (DMI) can be associated with the RLI to allow manipulation of the digits to be outpulsed. For this application, the DMI is used to remove the ZDP digits that were inserted in the dialed digits at the main office. The DMI is also used to convert the call type back correctly according to the incoming SPN pattern.
