DID

Direct Inward Dialing

A telecommunication service that allows a company to allocate individual phone numbers to each person or workstation within its private branch exchange (PBX) system without requiring a separate physical phone line for each. This enables direct calling to the extension within an organization without going through a manual switchboard or operator.

DIDs are commonly used to improve customer service and efficiency, as they allow employees to have direct lines, making it easier for clients and contacts to reach them directly. This can enhance communication and streamline operations, especially in larger organizations or call centers. Additionally, international DIDs can provide a business with phone numbers in various countries, allowing them to establish a local presence and making it easier for international customers to contact them at local call rates.
