Termination Rate is list of all prefixes, called Routes, with associated minute rates that should be sent to a particular Connection or group of Connections.
The role of Termination Rate is two fold:
- First of all, it defines complete list of pefixes that have to be route to a particular Connection or group of Connections. When Connection is associated with particular Termination Rate in Routing Group, only prefixes listed in that Destination Set will be routed to that Connection.
- Secondly, Termination Rate defines prices that will be charged by the termination provider (Vendor) when the call is being sent to that provider. Those prices will be used to track balance with each particular Vendor as well as to make routing decisions when Least Cost routing is enabled.
Billing parameters in Destination Set are:
- FreeSeconds - in seconds
- ConnectFee - in money units
- PostCallSurcharge - in percents
- GracePeriod - in seconds
The parameters above have the same meaning as similar parameters in Tariffs and they are used to calculate cost of the outgoing call.
Routes
Each Termination Rate can have set of prefixes attached to it. All those prefixes are called Routes.
For example
if you have service agreement with carrier FooTel, who provides you with access to two his SIP-to-PSTN termination gateways: one in the Moscow, Russia and the second one in London, UK there will be Vendor in the system representing that carrier, two Connections associated with that vendor and two Termination Rates. One Termination Rate will have Route with prefix 795 and the second with one with 44207 prefix. In addition, if those gateways can terminate calls to other destinations within the same area (mobile, nearby areas etc) there can be other prefixes in those two Destination Sets as well.
In addition, each Route has number of billing parameters matching the same parameters in Tariff Rates above and they are used to calculate cost of the outgoing call.
