Whitelist is used to allow incoming/outgoing numbers. Blacklist is used to block an incoming/outgoing call.
If the number of incoming or outgoing call is listed in the Blacklist, the caller will hear the following prompt: “The number you have dialled is not in service. Please check the number and try again”. The system will then disconnect the call.
The system supports to block or allow 3 types of numbers:
- Inbound: The number would be disallowed or allowed to call in the system.
- Outbound: Users are disallowed or allowed to call the number out from the system.
- Both: Both inbound and outbound calls are disallowed or allowed.
