Configuring Charge Codes - AudioCodes Mediant 1000B User Manual

When the call ends, the device sends an AOC-E Facility message to the PBX indicating the
total number of charged units.
The device supports various methods for AOC:

Tel-to-IP direction: The device converts the AOC messages received in the EURO
ISDN Facility IE messages into SIP INFO and BYE messages using AudioCodes
proprietary SIP AOC header.

IP-to-Tel direction provides optional methods:
•
The device generates the metering tones according to user-defined pulses and
intervals, configured in the Charge Code table (see ''Configuring Charge Codes''
on page 454). These include:
♦
♦
♦
•
TELES proprietary method. For more information, see the
PayPhoneMeteringMode parameter in Metering Tone Parameters on page 944.
•
Cirpack proprietary methods. For more information, see the
PayPhoneMeteringMode parameter.

To configure AOC:
1. Make sure that the PSTN protocol for the trunk line is Euro ISDN and set to network
side.
2. Make sure that the date and time of the device is correct. For accuracy, it is
recommended to use an NTP server to obtain the date and time.
3. For AOC in the Tel-to-IP direction:
a. Enable the AOC service for sending AOC to IP: on the Supplementary Services
page (Configuration tab > VoIP menu > GW and IP to IP > DTMF and
Supplementary > Supplementary Services), set 'AoC Support' to Enable.
4. For AOC in the IP-to-Tel direction:
a. Configure the AOC method: on the Supplementary Services page
(Configuration tab > VoIP menu > GW and IP to IP > DTMF and
Supplementary > Supplementary Services), configure the 'Generate Metering
Tones' parameter (PayPhoneMeteringMode).
b. If the AOC feature uses the Charge Codes table, configure Charge Codes (see
Configuring Charge Codes), and then assign the Charge Code index to the
relevant Tel-to-IP routing rule in the Outbound IP Routing table (see ''Configuring
Outbound IP Routing'' on page 383).
Note: This feature is applicable to Euro ISDN (PRI and BRI).

26.17 Configuring Charge Codes

The Charge Codes table lets you configure metering tones that the device generates to the
Tel side on its FXS interfaces, and for Advice of Charge (AOC) services for Euro ISDN
trunks (see Advice of Charge Services for Euro ISDN on page 453). To enable the
generation of metering tones, see Configuring Metering Tones on page 459.
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
User's Manual
'Pulses On Answer' - number of charging units in the first generated AOC-D
Facility message.
'Pulse Interval' - time between every sent AOC-D Facility message.
'End Time' - time at which the charge code ends.
