Uniform dial plan
You can also set up a Uniform Dialing Plan that can be shared among a group of servers. For
more information, see Feature Description and Implementation for Avaya Communication
Manager, 555-245-205.
Multi-Location Dial Plan
When a customer migrates from a multiple independent node network to a single distributed
server whose gateways are distributed across a data network, it may initially appear as if some
dial plan functions are no longer available.
The multi-location dial plan feature preserves dial plan uniqueness for extensions and
attendants that were provided in a multiple independent node network, but appear to be
unavailable when customers migrate to a single distributed server. This feature is available
beginning with Communication Manager, release 2.0.
For example, in a department store with many locations, each location might have had its own
switch with a multiple independent node network. The same extension could be used to
represent a unique department in all stores (extension 123 might be the luggage department). If
the customer migrates to a single distributed server, a user could no longer dial 123 to get the
luggage department in their store. The user would have to dial the complete extension to
connect to the proper department.
Instead of having to dial a complete extension, the multi-location dial plan feature allows a user
to dial a shorter version of the extension. For example, a customer can continue to dial 123
instead of having to dial 222-123.
Communication Manager takes leading digits of the location prefix and adds some or all of its
leading digits (specified on the Uniform Dial Plan screen) to the front of the dialed number. The
switch then analyzes the entire dialed string and routes the call based on the administration on
the Dial Plan Parameters and Dial Plan Analysis screens.
Note:
Before you can administer the multi-location dial plan feature, the Multiple
Note:
Locations field on the Optional Features screen must be enabled. To check if
this is enabled, use the display system-parameters customer-options
command. The Multiple Locations field is on page 3 of the Optional Features
screen.
