LANCOM VoIP Routers support two variants of the AOC (Advice Of Charge) service:
- AOC-D refers to the transmission of charge information during the call.
- AOC-E refers to the transmission of charge information at the end of the call.
LANCOM VoIP Routers transmit charge information from both types of AOC service between internal and external busses. AOC-D charge information can be converted into a metering pulse for analog users at the internal analog interfaces if the corresponding option has been activated.
