What is a DID?

You, as an IT or telecommunications provider, can develop a profitable business line for yourself by providing Direct Inward Dialing (DID) services. However, how do you persuade your clients that DID is something they actually need? The best thing you can do is get them to learn the basics first.

According to Cisco: “DID is a service offered by telephone companies that enables callers to dial directly to an extension on a Private Branch Exchange (PBX) or packet voice system without the assistance of an operator or automated call attendant. This service makes use of DID trunks, which forward only the last three to five digits of a phone number to the PBX or router/gateway.”

Basically, Direct Inward Dialing is a way to make calls without having to involve an operator. Using this option, your client would only need to purchase one phone line, but multiple direct numbers could still be routed to specific individuals or voicemails within their organization. 

In combination with SIP trunks, DID phone numbers will allow companies to receive calls directly from any device: VoIP, IP PBX, or analog PBX extension. DIDs allow companies to receive calls from any of their SIP trunk lines, so they don’t need a dedicated line for each. DID is scalable with SIP, so your customers can order as many as they need.
