What is a DID Number?
A DID (Direct Inward Dialing) number is a virtual phone number that routes incoming calls to a specific destination — such as a VoIP phone, PBX system, call center, or SIP endpoint — without requiring a physical phone line for each number.
DID numbers allow businesses to establish a local presence in any country or region without physical offices. When a customer dials a local DID number, the call is routed over the internet to your chosen destination, providing a seamless calling experience.
