Parameter Description
[CPTDetectorFrequencyDeviati
on]

58.10.9.3 Metering Tone Parameters
The metering tone parameters are described in the table below.
Table 58-64: Metering Tone Parameters
Parameter Description
Generate Metering
Tones
[PayPhoneMeteringMod
e]
Defines the method for configuring metering tones that are generated to
the Tel side.
 [0] Disable = (Default) Metering tones are not generated.
 [1] Internal Table = Metering tones are generated by the device
according to the Charge Code table and sent to the Tel side.
 [2] SIP Interval Provided = (Proprietary method of TELES
Communications Corporation) Advice-of-Charge service toward the
PSTN. Periodic generation of AOC-D and AOC-E toward the PSTN.
Calculation is based on seconds. The time interval is calculated
according to the scale and tariff provided in the proprietary formatted
file included in SIP INFO messages, which is always sent before 200
0K. The device ignores tariffs sent after the call is established.
 [3] SIP RAW Data Provided = (Proprietary method of Cirpack) Advice-
of-Charge service toward the PSTN. The received AOC-D messages
contain a subtotal. When receiving AOC-D in raw format, provided in
the header of SIP INFO messages, the device parses AOC-D raw data
to obtain the number of units. This number is sent in the Facility
message with AOC-D. In addition, the device stores the latest number
of units in order to send them in AOC-E IE when the call is
disconnected.
 [4] SIP RAW Data Incremental Provided = (Proprietary method of
Cirpack) Advice-of-Charge service toward the PSTN. The AOC-D
message in the payload is an increment. When receiving AOC-D in raw
format, provided in the header of SIP INFO messages, the device
parses AOC-D raw data to obtain the number of units. This number is
sent in the Facility message with AOC-D. The device generates the
AOC-E. Parsing every AOC-D received and summing the values is
required to obtain the total sum (that is placed in the AOC-E).
 [5] SIP 2 TEL INTERWORKING = Enables IP-to-Tel AOC, using
AudioCodes' proprietary SIP header, AOC.
Note: The parameter is applicable only to ISDN Euro trunks for sending
AOC Facility messages (see Advice of Charge Services for Euro ISDN on
page 537).
Charge Codes Table
[ChargeCode]
Defines metering tones and their time intervals that the Euro ISDN trunk
sends in AOC Facility messages to the PSTN (i.e., PBX).
The format of the ini file table parameter is as follows:
