6.7.3 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.
Figure 6-68 Blacklist List
We can add a number with the type: inbound, outbound or both.
Figure 6-69 Add a Number as Blacklist
Note: Add a phone number in blacklist, such as ―05921234567‖:
1) If the type is ―inbound‖, then this number can‘t be called.
2) If the type is ―outbound‖, then the extensions in MyPBX can‘t call this
number.
