The Blacklisted Number function disconnects calls for any number that appears in the Blacklist transformation table.
Add a Transformation Table. For detailed information, refer to Creating and Modifying Entries to Transformation Tables.
In the Input field (in Value), enter the number to be blacklisted (i.e., (\+14085559775) ). With the example Input field, a call from number 408-555-9775 will be automatically disconnected. You may add any number, or type of number, to the Blacklist Transformation table. The Blacklist is processed following the Number Normalization script, so normalized numbers should be entered into the Blacklist.
Create an Action to disconnect calls that are included in the Blacklist Transformation Table.
Create an Entry in the Action Set Table. For details, refer to Creating and Modifying Entries to Action Set Tables.
Add an entry to the main Action Set using the Translation Table.
