Common Networking Features

Alternate Route Selection

Alternate Route Selection (ARS) allows calls to be routed via the optimum carrier. Time profiles can also be

used to allow customers to take advantage of cheaper rates or better quality at specific times of day.

If a primary trunk is unavailable or congested, then ARS provides automatic fallback to an available trunk (e.g.,

analog trunk fallback if a T1 or SIP trunk fails, or use PSTN for SCN fallback).

Multiple carriers are supported. For example, local calls are to go through one carrier between specific hours

and international calls through an alternative carrier. Carrier selection using 2-stage call set up via in-band

DTMF is possible. It is possible to assign specific routes on a per user basis, e.g. only allow expensive routes to

be used by critical staff.

Note: Existing Least Cost Routing (LCR) configurations are automatically converted to ARS when upgrading to

4.1 or higher.

Network Numbering Schemes

IP Office uses fully flexible network numbering options. Dialed digits can be manipulated to add or remove

digits, access codes etc. in order to fit into any numbering scheme. Two types of numbering schemes are

commonly deployed - 'Linked Numbering' and 'Node Numbering' schemes. In linked numbering schemes each

site within the network has a unique range of extension numbers and users simply dial the extension number of

the called party. Often, linked numbering schemes are used in very small networks (< 5 sites) with less than

500 extensions. With node numbering schemes each site is given a node ID and this is prefixed by the user

when dialing extensions at other sites. In this way extension numbers can be replicated across sites while still

appearing unique across the network. Node numbering schemes are common in larger networks. Linked

numbering schemes and node numbering schemes are sometimes both used within the same network with

node numbering used at the large offices and linked numbering employed at clusters of satellite offices.

The following figures depict these two types of numbering schemes.
