Open the ROUTING.CFG file found in the \config folder within the main program folder.
Calls can be priced differently when made over certain trunks, by particular extensions, by using different trunk access codes, and from different sites.
This is made possible by use of this routing table. Some criteria takes precedence over others and the hierarchy is as follows:
- Extension Routing
- Least-Cost Routing
- Hard Trunk Routing
- Trunk Access Routing
- Site Routing
Each set of criteria should be listed in its own section. Sections are defined by inserting the section name in square brackets.
A typical routing configuration may look like this:
In this example, assuming the default tariff table is set to BT, then any call data from the site 'Default Site' would be reinforced as a BT call.
If, however, a call was made using the trunk access code 78, it would be costed as a PrivateWire call.
This would be overridden if the call was made over any of the trunks 2001 to 2007. In this case it would be costed at NTL rates.
However, taking precedence above all of this, if the call was made from any of the extensions 3000 to 3003, it would be priced using the Payphone rate.
