AudioCodes MediaPack MP-11 Series User Manual

Version 7.2 569 Mediant 1000B Gateway & E-SBC
User's Manual 26. Configuring Supplementary Services
The device supports various AOC methods:

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.

Device Generation of AOC to Tel: 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
570). These include:
• '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.

IP-to-Tel Direction:
• SIP-to-Tel interworking: The device uses the AOC header from the IP side and
sends to Tel in EURO ISDN Facility IE messages. Below shows the SIP AOC
header:
AOC: charged; <parameters>
Where parameters can be:
♦ state="active" or "terminated"
♦ charging-info="currency" or "pulse"
If "currency", the following parameters are available:
♦ currency=<string>
♦ currency-type="iso4217-a" or <string>
♦ amount=<number>
♦ multiplier=("0.001","0.01","0.1","1","10","100","1000")
If "pulse", the following parameter is available:
♦ recorded-units=<number>
• TELES proprietary method
• Cirpack proprietary methods
For more information on the proprietary methods, see the PayPhoneMeteringMode
parameter in ''Metering Tone Parameters'' on page 1123.
 To configure AOC:
1. Make sure that the PSTN protocol for the trunk line is configured to Euro ISDN and
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. For more
information, see ''Date and Time'' on page 119.
3. Configure the required AOC method:
• Device Generation of AOC to Tel:
a. Open the Supplementary Services page (Setup menu > Signaling & Media
tab > Gateway folder > DTMF & Supplementary > Supplementary
Services Settings), and then configure the 'Generate Metering Tones'
parameter (PayPhoneMeteringMode) to Charge Code Table.
Figure 26-14: Configuring Metering Tone Method
b. In the Charge Codes table, configure Charge Codes (see ''Configuring
Charge Codes'' on page 570).
