Call Advice of Charge Commands

This set of commands enables GSM operators to offer Advice of Charge (AoC) services that
calculate call charges. These charges are expressed in terms of home units.

+CAOC, Advice of Charge

This command displays information about the cost of calls. If supported, this command also
activates/deactivates unsolicited event reporting of the CCM (Current Call Meter) information.
The unsolicited report +CCCM:<ccm> is sent when the CCM value changes, but not more than
once every 10 seconds.

The CCM value depends on the network properties (charge for MO or/and MT calls).
There are two states in which the command can be activated:
• In IDLE state - returns the last call cost.
• In a voice/data state - returns the accumulated cost, including the current call.
