Black List/White List

UC-Series VoIP PBX allows you to add specific number to black list and white List. This article briefly introduces the definitions and basic settings of black List and white list, and provides related configuration examples.

What is Black List and White List?

We briefly introduce the definitions of black list and white List as follows.

• Black List

  The black list is used to filter phone numbers. If a phone number is added to the black list, the system blocks incoming or outgoing calls for the phone number.

• white List

  The white list is used to add trusted phone numbers. If a phone number is added to the white list, the system allows incoming or outgoing calls for the phone number.

Black List/White List Setting

UC-Series VoIP PBX supports system black list/white list and personal black list/white list. You can set a system black list/white list to apply to all extensions.

• System Black List and White List

  Log in the PBX web interface as an administrator, and go to PBX > Call Control > Call Restriction > Black List/White List to set black list and white list.

  UC-Series VoIP PBX supports to block or allow three types of numbers:

  • Inbound: If black list type is set to Inbound, the number can not call in the system; if white list type is set to Inbound, the number can call in the system.

  • Outbound: Extension users can not call the number whose black list type is Outbound; extension users can call the number whose white list type is Outbound.

  • Both: Neither inbound calls nor outbound calls are allowed for the number whose black list type is Both; both inbound calls and outbound calls are allowed for the number whose white list type is Both.

Black List Example

We demonstrate a few examples of blocklist as follows.

Prohibit inbound calls from external numbers

For example, 10086 and 1008611 are not allowed to call in PBX. You can add the two numbers to black list as follows.

Open

Prohibit selected extensions or extension groups from calling certain numbers

• Prohibit selected extensions from calling 10086 and 1008611.
