Apply Prefix Set

Prefix Sets can be applied to the following locations under the Management menu:

  • Customer Routing Basic Dial String Prefix Set
  • Routing Global Basic Dial String Prefix Set
  • Rate Card Customer Rate Cards Profits Config Prefix Set


Use Flags to create a Global CLI Blacklist or a Global Dialled Number Blacklist (Aka Block List). This will prevent all calls going through the system which match the prefix set added


Flags are used for large amounts of numbers that change infrequently. If you are looking to manage a DNC list, take a look at our ScriptForge Options.
