TIM Professional allows you to apply different rates to specific calls, depending on whether they were made over certain trunks, by particular extensions, by using a particular trunk access codes or from specific sites. This can be achieved by creating a routing table, such as the one shown below.
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, which will be defined by inserting the section name in square brackets.
A typical routing configuration may look like this:
In the example above, assuming the default tariff table is set to BT, any call data from the Default Site would be reinforced as a BT call.
If, however, a call was made using the trunk access code 78, this would be costed as a PrivateWire call. This would be overridden if the call was made over any of the trunks 2001 to 2007 and it would be costed at NTL rates. In the same way, if the call was made from any of the extensions 3000 to 3003, it would be priced using the Payphone rate, taking precedence above all other conditions.
