Least Cost Routing

To set up the feature you associate dialled digits (Input Codes)

with the lines over which calls should be routed and with

whatever network codes (Output codes) are necessary to route

the call.

In addition, you may choose to route the calls over different

lines at various times of the day for optimum call rates.

The feature can be turned on permanently or activated at

particular times.

Once the facility is activated, calls are automatically routed over

the selected lines, and the network code (Output Code) is

dialled automatically on the line before the telephone number.

Using this page you may define the Least Cost Routing criteria.

Up to 30 LCR rules may be defined (Index 1 – 30).

In the ‘Input Code’ field you insert the relevant dialled digits (e.g.

‘00’ for International calls or ‘001’ for International calls to the

USA).

In the Output Code field, you insert whatever digits you want to

be passed to the network. If no additional carrier access codes
