Notes:
• The Metering Tones page is available only for FXS interfaces.
• Charge Code rules can be assigned to routing rules in the Tel to IP
Routing (see 'Configuring Tel to IP Routing' on page 223). When a new
call is established, the Tel to IP Routing 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.
 To configure Metering tones:
1. Open the Metering Tones page (Configuration tab > VoIP menu > GW and IP to IP >
Analog Gateway > Metering Tones).
Figure 25-2: Metering Tones Page
2. Configure the Metering tones parameters as required. For a description of the
parameters appearing on this page, see 'Configuration Parameters Reference' on
page 421.
3. Click Submit to apply your changes.
4. To save the changes to the flash memory, see 'Saving Configuration' on page 324.
If you set the 'Generate Metering Tones' parameter to Internal Table, access the Charge
Codes Table page by clicking the Charge Codes Table button. For more information
on configuring the Charge Codes table, see 'Configuring Charge Codes' on page 263.
25.3 Configuring Charge Codes
The Charge Codes table is used to configure the metering tones (and their time interval)
that the FXS interfaces generate to the Tel side. To associate a charge code to an
outgoing Tel-to-IP call, use the Tel to IP Routing.
You can configure up to 25 different charge codes, where each table row represents a
charge code. Each charge code can include up to four different time periods in a day (24
hours). The device selects the time period by comparing the device 's current time to the
end time of each time period of the selected Charge Code. The device generates the
Number of Pulses on Answer once the call is connected and from that point on, it
generates a pulse each Pulse Interval. If a call starts at a certain time period and crosses
to the next, the information of the next time period is used.
Notes:
• The Charge Codes Table page is available only for FXS interfaces.
• The Charge Codes table can also be configured using the table ini file
parameter, ChargeCode.
