Voip Number (DID Number)


Direct inward dialing (DIDs) are virtual numbers DID that allow you to route calls to your existing telephone lines. DIDs were developed in order to be able to assign certain employees a direct number, without requiring multiple physical phone lines. These numbers are designed to forward incoming calls to one of the pre-set telephone, chosen by the client: fixed, mobile or VoIP. A virtual number can work like a gateway between traditional calls (PSTN) and VoIP.

Most businesses have several incoming telephone numbers used for specific purposes. For example customer service, sales, etc. Some have an individual telephone number for each user in the system. In a home setting on the other hand, each telephone number comes in on a different pair of wires typically. This is not practical in a business environment that has many telephone numbers.

In modern PBX’s, typically, digital methods are used to do the same thing, ie. supply the “called party” information. Many business’s still have old PBX’s which use the analog signalling I mentioned before. The type of telephone lines used for analog DID are different than regular home telephone lines. Usually, battery voltage is supplied by the business PBX instead of the telco, also, the telco signals a new call by bridging the line instead of by ringing the line. The receiving PBX signals back that it’s ready to take the call by momentarily reversing polarity of the voltage on the line (this is called “winking” the line)
