b. Configure the Charge Codes in the Charge Codes table (''Configuring
Charge Codes'' on page 539).
c. Assign the Charge Code index to the relevant Tel-to-IP routing rule in the
Tel-to-IP Routing table (see ''Configuring Tel-to-IP Routing Rules'' on page

Supplementary Services), set 'AoC Support' to Enable, to enable the AOC
service for sending AOC to IP.
• AOC in the IP-to-Tel Direction: On the Supplementary Services page
(Configuration tab > VoIP menu > GW > DTMF and Supplementary >
Supplementary Services), configure the 'Generate Metering Tones' parameter
(PayPhoneMeteringMode) to the required method (SIP Interval Provided, SIP
