Embedded Gatekeeper MultiVOIP User Guide

When one of the zone prefixes is defined, no calls from other zones can reach this zone, unless preceded by the prefix. If an endpoint in a zone dials a zone prefix before its number, and the Gatekeeper cannot resolve it in its zone, the Gatekeeper attempts to locate and route the call to a Neighbor Gatekeeper with the same prefix. For such calls, the Gatekeeper strips the zone prefix and then applies the destination location mechanism to route the call to its final destination.

You can use the zone prefix to devise a dialing plan in a multi-zone environment. If zone prefixes are not defined, the zone accepts the following calls:

•Calls prefixed to a service defined in the zone and allowed as default.

•Calls to on-line terminals in the zone.

•Calls to terminals marked as Forward in the zone.

Example of comparing Zone prefix use when using Zone prefixes

•Zone A has a 01 prefix. In this zone, the phone number of user A1 is 123 and the phone number of user A2 is 456. The Gateway service has a prefix of 8.

•Zone B has a 02 prefix. In this zone, the phone number of user B1 is 123 and the phone number of user B2 is 456. The Gateway number is 555444 and the Gateway service has a prefix of 9.

•A1 calls A2 by dialing 456.

•A1 calls using zone A Gateway 8555444.

•A1 calls B1 by dialing 02123.

Note: The call is completed only if the Gateway service is allowed as default in Zone B.
