Overview

Direct Inward Dialing (DID) numbers are phone numbers used for various services, including geographic, non-geographic, toll-free, and premium calls. Service providers typically acquire these numbers from a DID provider, paying activation fees and recurring monthly charges.

In PortaBilling, DID numbers are managed through the DID inventory, which enables administrators to maintain a comprehensive list of numbers, track costs, and set customer pricing by applying markups to both activation and recurring fees. Customers can also view and manage their assigned DID numbers via the self-care portal.
