Direct Inward Dialing (DID)

Direct Inward Dialing (DID) is a telecommunication service offered by telephone companies to organizations that operate a private branch exchange (PBX) system.

DID allows external callers to directly reach a specific extension within the organization without going through an operator or a menu system. 

  • Direct Connection to Extensions: With DID, an organization can allocate individual phone numbers for each extension within its PBX system. This allows external callers to dial directly to a specific desk or office within the company.

  • Efficiency in Call Handling: DID improves the efficiency of handling incoming calls, as it bypasses the need for a receptionist or automated attendant to route calls internally.

  • Multiple Phone Numbers: An organization can have a range of external phone numbers for different departments or employees, even if the physical lines coming into the PBX are fewer than the number of DID numbers.

  • Cost-Effective: DID is cost-effective for businesses as it reduces the need for multiple physical phone lines and streamlines the call routing process.

DID is a practical solution for businesses and organizations looking to manage large volumes of incoming calls effectively and provide direct contact access to various departments or personnel.
