DID (Direct Inward Dialing) numbers are virtual phone lines that allow callers to reach specific extensions or departments directly, bypassing a central operator. Used in VoIP-based PBX systems, DID numbers help streamline inbound calling and reduce the need for physical lines. They’re commonly used in call centers, remote offices, and multinational teams. With cloud integration, calls to a DID number can be forwarded anywhere in the world, enabling efficient, location-independent communication.
