Configuring a DIDs Count
ARM supports phone numbers (DIDs) counting. The feature allows operators to prevent DDOS/DOS and calls flooding attacks on the enterprise. DID calling (or called) with suspicious frequency can be handled as bothersome and disruptive, and can be blocked by using the ARM’s generic routing capabilities.
