Billing
To get information about the price of an outgoing call from the gateway to a GSM
network, you can activate transmission of this information from the GSM gate to ISDN
terminal via the AOC service. The information may be generated in two ways.
- Transmit Aoc information from GSM, the information about the price of the call is
received from the GSM network and transformed into the AOC service. The subscriber
gets accurate information about the price. NOTE: Only some providers offer this service.
- Off, the AOC service is inactive, no information is transferred to the ISDN.
- Generate, in case the GSM network does not support transferring charge information
you can activate this parameter to start generating this information in the gateway – this
information may slightly differ from the actual cost. After activation, the following two
items should be added:
- Number of tariff impulses, this parameter determines how many impulses are
transmitted after the connection is established.
- Pulse repetition time is the time period of sending another impulse after the initial
series of impulses.
