DID (Direct Inward Dialing)

Direct Inward Dialing (DID) is a telecommunications service that allows a caller to dial a direct telephone number to reach an individual extension within a private branch exchange (PBX) system. In other words, instead of having to go through a company's main phone number and navigating through an automated system or a receptionist, a caller can dial a unique phone number assigned to a specific extension and be directly connected to the intended recipient.

DID numbers are typically provided by telephone companies or VoIP service providers and can be local, national or even international phone numbers. The numbers are mapped to the corresponding extensions in the PBX, so when a call is made to a DID number, it is routed directly to the designated extension without going through a switchboard or receptionist.

DID is commonly used by businesses to streamline their communication processes, reduce call wait times, and improve customer experience. It allows companies to have their a local phone number, which can help improve their accessibility and efficiency. Additionally, DID can be used to track call volumes, monitor call patterns, and provide detailed call reports, which can be helpful for businesses to analyze their call traffic and optimize their communication strategies.
