Blacklist
Blacklist is used to block an incoming/outgoing call. If the number of
incoming/outgoing call is registered 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.
Go to
PBX→Advanced Settings→Blacklist
to add numbers to the blacklist.
You can choose to block the number for inbound, outbound or both.
If the type is
―inbound‖, then this number can’t be called.
If the type is
―outbound‖, then the extensions in S2400 can’t call this number.
