DID Numbers

The telephone company which provides one or more trunk lines to the customer for connection to the customer's private branch exchange (PBX) systems. In this current time, Voice-over-IP providers commonly refer to individual number provided to their subscribers as DIDs.

The Direct Inward Dialing (DID) service for VoIP provides access to local telephone numbers in most of the countries around the world, it doesn’t need any physical presence in any other countries. Calls to these DID virtual numbers are then forwarded by companies to PSTN or mobile networks, VoIP carriers, or SIP/IAX servers.

This means that:

• International and long distance telephone calls can be possible only with the help of the caller by paying local call rates. To understand more clearly, let’s have a glance on Example, your family lives in place Pakistan and you lives in Dubai. When you might be thinking to call your family with general number that may cost you much. To prevent such unnecessary expenses. You have to purchase a India DID, and then anyone dialing that local number in India would connect to your phone in UK; here they will be charge local phone rates only, no extra cost.
• Add telephone numbers to your phone line that you are no longer restricted to one telephone number per line. This process can be only useful if a virtual telephone contact point is required in more than one country.
• Conventional telephone calls may be terminated at Non-Public Switched Telephone Network(PSTN) devices such as VoIP. This has particular relevant for VoIP communications, as it allows people connected to the traditional PSTN network to call people connected to VoIP networks.

Besides these basic functions of DID numbers, there are many additional uses for local numbers. If users wants to advertise services on a website and they wish prospective buyers to contact them without publishing their own, private telephone number and then DID virtual number could be used.
