If you have ever called a business and reached a specific employee, department, or team directly without going through a receptionist, you may have used a DID (Direct Inward Dialing) number. DID is a telephony feature that gives users individual phone numbers or extensions so incoming calls can be directed to the right person, department, or service.
How Does a DID Number Work?
- A business gets one or more DID numbers from a telecom or cloud telephony provider
- Each DID number is assigned to a specific employee, department, team, or service
- A customer calls the DID number directly
- The telephony system identifies the assigned destination and routes the call accordingly
- The call can be connected to an agent, IVR, extension, softphone, or other configured destination
