Dialling Restrictions allow granular control over numbers that are allowed to be dialled from the platform.  Dialling restrictions are created in the Dialling Restriction menu item in each of the relevant submenu item links, and are applied en masse there, but individually to extensions in the Extension Manager.

Block Lists

Block lists are lists of numbers that have been determined to be restricted and cannot be contacted.  

Multiple block lists can exist, including the default block lists. These lists can include varying levels of restrictions and be applied separately to different extensions, thus allowing very granular control.

The system allows blocking a specific number or blocking entire number blocks by using wildcards; for example, adding * will indicate any number or amount of digits. With wildcards, either block restrictions can be applied, such as “all” with 0*, or specific prefixes can also be blocked, such as 02* or 06*.

When creating a block list, it is recommended to not use the tenant name as the name of a block list. 

Within the block list table, the number of items in each list is visible, as well as the number of extensions currently assigned to that block list in their individual tabs.  

Country Lists

Country lists allow for international dialling restrictions. Like block lists, it is possible to create specific lists or utilise the default ones. To allow destinations, simply make sure the particular prefix is enabled within the relevant country list. The TMS automatically updates when a country code is enabled/disabled. 

Staff can be assigned to country lists by dragging and dropping the available member to the “Assigned” members column from the Assignments tab. 

Note: When enabling the first country code on the first list (Canada), the entire Zone will be enabled as the country code strts with +1 and therefore, the rest will automatically be enabled.Ensure that countries with a high risk of Toll fraud are disabled unless explicitly required.

Allow Lists

Allow lists allow specific numbers to be dialled over and above restrictions placed by block lists and/or Country Codes (if international calling is allowed). This feature can be used to grant access to a specific number in a dialling range even though the dialling range is blocked. Allow lists numbers are tested against the entire number dialled or made use of the wildcard (*). To allow calling to any Cape Town number, enter 021*.
