What is Direct Inward Dialing (DID)?
Direct Inward Dialing (DID) is a feature of phone systems that enables external callers to reach an internal extension directly, without needing to go through a switchboard or an attendant. Each user or extension within an organization is assigned a unique external phone number, allowing external callers to dial specific individuals directly, bypassing the need for a receptionist.
To enable DID, telephone service providers connect a block of telephone numbers to your company’s Private Branch Exchange (PBX) system.
DID allows businesses to create virtual numbers that route callers directly to specific desk extensions or groups of extensions, avoiding the main reception line. These DIDs can be used with local, premium-rate, or toll-free numbers, providing flexibility, customized call routing, and contributing to a more professional image for the business.
What is Direct Inward Dialing (DID) & How Does It Work?
Direct Inward Dialing (DID) is a telephone service that enables a specific phone number to connect directly to a designated phone within a business, bypassing the need to navigate through a menu or call queue to dial an extension. Such numbers are referred to as “DID” numbers, and if multiple, they are called “DIDs“.
The advantage of a DID is that it allows callers to directly contact an employee without the intervention of an automated system, receptionist, or call center. This is distinct from internal phone extensions, which are only functional within the company’s own phone system.
