World-Class Routing

Avaya IP600 is a world-class system that meets the needs of global customers. One capability essential in meeting these needs is the ability for users to flexibly dial any location in the world, regardless of the dial plan used at that location. To fulfill this requirement, Avaya IP600 provides World-Class Routing.

World-Class Routing is a powerful enhancement to Avaya IP600’s call-routing capabilities, linking several call-routing features to build a communications network capable of providing flexible call routing for any type of dialing plan while accommodating changes in both international and domestic dialing plans.

The following are key components of World-Class Routing:

•Digit Conversion converts a dialed number for public network number to a private network number and vice versa. Dialed numbers matching entries in the digit conversion tables are treated and converted. Converted calls can be routed via the most optimum route, resulting in reduced network charges and appropriate use of the private network.

•Toll Analysis compares a dialed number to entries in the system’s list. Based on the results, calls may be restricted from completion.

•Automatic Route Selection (ARS) digit analysis compares a dialed public network number with entries in the system’s tables, mapping the number to a selected public network routing pattern.

•Automatic Alternate Routing (AAR) digit analysis compares a dialed private network number with entries in the system’s tables, mapping the number to a selected private network routing pattern.

World-Class Routing supports the ARS and AAR as separate features, but through generalized administration applicable to both features, provides both with the same routing abilities. In addition, there are a number of capabilities that enhance the flexibility of routing in supporting your domestic and/or global calling requirements.

For example, 18-digit routing allows Avaya IP600 to determine call routing by analyzing up to 18 digits with no restriction on the grouping or format of the digits, eliminating any assumptions about the use of a particular dialing plan.

International Direct Distance Dialed calls generally consist of an international access code, a country code, and a national number. Both codes may vary in length. Avaya IP600’s support for International Direct Distance Dialed calls eliminates any restriction on the grouping and format of digits on ARS numbers. Call routing is determined by the digits and the length of the dialed number.

Multinational World-Class Automatic Alternate Routing allows the Automatic Alternate Routing number (Electronic Tandem Network number) to be any number of digits in length.

Digit conversion can be used to reroute numbers, initially dialed to use ARS, into AAR and vice versa. This utility can analyze a maximum of 18 digits. In this way, destinations in a customer’s network can be called using the public network number. This feature can also be used to reroute certain Direct Distance Dialed destinations to specified alternate destinations (such as intercept, attendant, or another Direct Distance Dialed number).
