What is DID?
Information About Technology
Core Definition
A DID (Direct Inward Dialing), also known as a virtual phone number or direct dial-in, is assigned to a specific phone extension, user, or department within a company’s phone system. It allows incoming calls to bypass traditional PBX menus or automated attendants, offering callers a direct and seamless connection to their intended contact.
Benefit Definition
DIDs streamline business communications in several key ways. They enhance customer experience by eliminating wait times and complex phone menus. They also boost the professional image of a company, particularly for small businesses, by providing dedicated phone lines for individuals or teams. Additionally, DID numbers can be geographically diverse, allowing a company to establish a virtual presence in various locations.

Technical Definition
DIDs are provisioned through telecommunications providers and operate using VoIP (Voice over Internet Protocol) or traditional telephony systems. The provider maps each DID number to a specific destination within the company’s phone network. When a call arrives, the provider’s systems follow these preconfigured routing instructions to connect the caller directly to the correct extension or user.
