Virtual Phone Number

A Virtual Phone Number is a phone number with call forwarding capabilities that isn’t connected to any specific phone line or SIM-card. It can be used for receiving and making calls – just like regular phone numbers.

In this article we will explain what a Virtual Phone Number is and how you can get one.


Virtual numbers can connect calls anywhere

Normal phone numbers are configured by the local phone company to connect incoming calls to physical phones connected to their network or to mobile phones that have SIM-cards registered with their mobile network.

This means that normal phone numbers are connected to something physical.

Virtual numbers on the other hand are not connected to anything physical.


Configurable destination

The destination of incoming calls to a virtual phone number is configurable by the subscriber, allowing incoming calls to be answered with apps in a laptop or mobile – across the Internet.

Both normal numbers and virtual numbers support call forwarding. This means that incoming calls can be sent onward to some other phone number, anywhere on the planet.

There is usually an extra charge for the call forwarding – as the onward call is a second outbound call, that is bridged together with the incoming call.


What can a virtual number be used for?

You can use virtual numbers in many different ways. Here are some examples.


Business use

Making calls with virtual phone numbers

Most providers of virtual phone numbers  allow you to make calls with your virtual number.

Here are the different techniques available for making calls with virtual numbers.


Across the Internet

With this option your call travels across your Internet connection to the provider of the virtual phone number.

If the destination of your call is a regular phone number, the provider will connect your call onward onto the regular phone network to the number you dialed.

The person you call sees your virtual number, regardless of where in the world you are.

Calls can be made with an app of software across the Internet from a phone or laptop. Many providers provide you with proprietary apps to be used with their service for making and receiving calls.

Some providers also allow third party apps or physical desktop phones using standards such as SIP to be connected to their service. This is however error prone, since the standards are not always implemented in the same way. Firewalls and so called NATs can additionally cause calls or audio to fail.


Call back

There are many ways to set up call back calls, but the general principal is that the provider sets up a mobile call to you and to the phone number you want to call, and then bridges the calls together. You pay for two local calls – but usually make a saving by not having to pay for an international call.

The way it would normally work is that you in a mobile app select a contact or enter a phone number to call, and then press “Call”. The provider’s system would call you, and as soon as you answer the call, they would start a second outbound call to the phone number you wanted to call, and then bridge the two calls together automatically.

The person you call sees your virtual number, regardless where in the world you are.


Call thru

With this approach, the provider’s mobile app would do the following after you enter a number or select a contact to call; The app would ask your mobile to make a regular mobile call to a local access number that the provider has in your country. As soon as the call gets connected, the provider would set up a second call onward to the phone number you wanted to call.

For you, it is like making a regular call. The person you call will see your virtual number.

You would pay your mobile provider for the local number -unless you have free minutes – and the virtual number provider for the other call to the destination number.
