1.2.2 Blacklist/Whitelist
Blacklist is used to block an incoming/outgoing call. If the number of incoming or outgoing call is
listed in the number blacklist, the caller will hear the following prompt: “The number you have dialed
is not in service. Please check the number and try again”. The system will then disconnect the call.
Whitelist is used to allow incoming/outgoing numbers.
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.
