While most businesses have several incoming telephone numbers used for specific purposes, there is often an individual telephone number for each user in the system. At the same time, home telephones usually each have different pair of wires and for obvious reasons that would not work in the business environment.
And that, in part, is why “Direct Inward dialing” (DID) was invented; as a way to use a limited number of physical phone lines to handle calls to different published numbers. In a business with DID, the phone company uses DID signaling to identify the number they are about to connect to the business's PBX (News - Alert).
One company handling the exploding growth in DID, and DDI, is Super Technologies. Its DIDX services empower the world of service providers with local international phone numbers from more than 55 countries in its online marketplace at DIDX.net. It is a one sign-up away.
The company has created a huge and new vertical market for CLEC, ILEC and local regional telecom's to make revenue from their pool of allocated DID numbers.
DID is used when a PBX telco connection allows direct dialing to extensions within a PBX, using physical lines that are shared. The DIDX service identifies the "called party" by using DTMF or by digital means, before connecting each call.
For their part, Super Technologies’ the DIDX (DIDXchange (News - Alert)) is where Internet protocol communications companies buy and sell DID (Direct Inward Dialing) phone numbers.
The service is designed for providers of Internet Telephony (News - Alert) Service, Instant Messengers, Wireless Operators, Competitive Local Exchange Carriers, Incumbent Local Exchange Carriers, Social Community Portals, and Communications Entrepreneurs.
The service has no membership fee.
