Configuring Metering Tones
The FXS interfaces can generate 12/16 KHz metering pulses toward the Tel side (e.g., for connection to a pay phone or private meter). Tariff pulse rate is according to the device's Charge Codes table. This capability enables users to define different tariffs according to the source/destination numbers and the time-of-day. The tariff rate includes the time interval between the generated pulses and the number of pulses generated on answer.

Charge Code rules can be assigned to routing rules in the Tel-to-IP Routing table (see Configuring Tel-to-IP Routing Rules). When a new call is established, the Tel-to-IP Routing table is searched for the destination IP address. Once a route is located, the Charge Code (configured for that route) is used to associate the route with an entry in the Charge Codes table. |
