What is an SIP trunk provider?

A SIP trunk provider is a service that offers SIP (Session Initiation Protocol) trunks to businesses or individuals. SIP trunks are virtual communication channels that enable the transmission of voice, video, and other unified communications over the internet.

SIP trunk providers allow users to make and receive phone calls, as well as engage in various forms of real-time communication using VoIP (Voice over Internet Protocol) technology. Think of an SIP trunk provider as a bridge between your phone system (PBX - Private Branch Exchange) and the outside world, facilitating the connection of your calls over the internet.

What are DID numbers?

DID stands for "Direct Inward Dialing," and DID numbers are telephone numbers that are directly associated with individual extensions within a private branch exchange (PBX) system or VoIP (Voice over Internet Protocol) network. These numbers enable external callers to reach specific internal extensions directly, without having to go through a receptionist or an automated menu.

DID numbers are often used in conjunction with SIP (Session Initiation Protocol) trunking and VoIP services, allowing businesses to manage and distribute incoming calls more effectively.
