Virtual Private Branch Exchange VPBX Definition. Virtual PBX is a privately held communications service provider that claims to have invented the type of private branch exchange technology called a virtual PBX. We also provide free Fully hosted PBX with all numbers in form DIDnPBX on our other platform www.didnumberprovider.com
The advent of Virtual Numbers (DID) services provides people with access to local telephone numbers in most countries on a worldwide basis. These numbers are then forwarded by companies such as BuyDIDNumber to PSTN (Plain Old Telephone System), VoIP or VoIM devices anywhere in the world. Essentially, this means that: 1. International and long distance telephone calls are made with the caller only paying local call rates. For example, your family lives in Paris, France but you live in NY, USA. You would like your family to be able to call you, but the long distance rates from France are very costly. If you purchase a Paris DID, anyone dialing that local number in Paris would connect to your phone in NY, but they would pay only local phone number rates. 2. You are able to add telephone numbers to your phone line so that you are no longer restricted to one telephone number per line. For example, you live in NY, USA but you have family in Paris, London and Beijing. You if you purchase DID numbers in Paris, London and Beijing, then anyone dialing those local numbers would connect to your phone in NY, USA. 3. Conventional telephone calls may be terminated at non-PSTN devices if desired, for example VoIP, or GTalk. This has particular relevance for VoIP communications, as it allows people connected to the traditional PSTN network to call people connected to VoIP networks. Moreover these basic functions of DID numbers, there are many additional uses for local numbers. For example, consider the issue of privacy. If users place classified advertisements in a newspaper and they wish prospective buyers to contact them without publishing their own, private telephone number, a temporary local number could be provided by the newspaper.
A SIP phone is a special VoIP phone that provides the traditional call functions of a telephone, such as dial, answer, reject, hold/unhold, and call transfer. SIP phones may be implemented as a hardware device (adapter to your regular phone) or as a softphone. An IP phone uses Voice over IP technologies allowing telephone calls to be made over an IP network such as the internet instead of the·ordinary·PSTN system.
This function allows you to receive calls to your DID numbers on regular land line or mobile phones. No internet, PC or VoIP services are required. Remember that in this case you pay a per-minute forwarding charges as well.
