What is a virtual phone service?

Virtual phone service refers to telephony solutions that are hosted in the cloud and delivered via the internet, which lets you make calls from any laptop or mobile device. The modern virtual phone service combines the best of landline technology with the flexibility of web-based services. As a result, you don’t just get a solution for making voice calls—you get a complete virtual phone service that manages your incoming calls and lets you send internet fax and SMS as well as host and join conferences from anywhere.

Why go virtual with your telephone service?

Voice over Internet Protocol refers to the technology that allows us to make and receive phone calls over the Internet in real time. It is a set of protocols working together to deliver internet telephony functions similar to regular phone lines or PSTN (public switched telephone network). The difference is that VoIP phone service provides flexibility and mobility that is not possible with traditional telephony. By delivering voice calling functions over internet connections, it allows anyone to use Voice over IP from anywhere via their laptops, desktops, or smart devices.

How does a virtual phone service work?

The whole concept of virtual phone service is to be able to do what traditional landlines and office phone systems do, but adding mobility to the mix by delivering the service via the internet.

What you get is a communications solution that can be accessed from anywhere and on any web-connected computer or mobile device.

But how is it able to imitate the functions of a traditional landline and phone system?

To better understand the technology, let’s check out the components of a virtual phone service versus the components of its traditional counterpart.

Virtual phone numbers vs traditional phone numbers

Traditional phone numbers are directly connected to a specific place through telephone cables. Virtual phone numbers are the exact opposite. The physical limitations that apply to traditional phone numbers do not apply. They are not tethered to a single line or device and can be accessed from anywhere.

In addition, businesses can get phone numbers for different area codes without having to have a physical presence there precisely because they are virtual. It gives companies another level of flexibility that they can’t get with traditional telephone numbers.


A public switched telephone network (PSTN) is the traditional method of connecting phone calls. It uses circuit-switched phone technology to transmit voice. PSTN uses the telephone carrier’s infrastructure, so every call made is charged based on the use of this resource.

VoIP, on the other hand, harnesses the flexibility of the internet to connect phone calls from any web-connected device. VoIP works through packet switching, where the voice data is broken up into multiple small packets that are transmitted over the internet, which are then reassembled and played on the receiver’s end in real-time. This is possible through a set of protocols working together to mimic the telephony function of PSTN. But because it does not use the regular carrier’s networks for transmitting voice calls, it greatly reduces your call costs, especially on long-distance calls, while getting more flexibility by being accessible from anywhere there is internet connection.

Cloud-hosted PBX vs on-premise PBX

On-premise PBX, as the name implies, is the on-premise call routing component of traditional office phone systems. The main infrastructure consists of a number of servers housed within the building it serves. What it does is that it receives all incoming calls and routes them to the right extensions.

Cloud-hosted PBX, on the other hand, performs the same function, except it is housed remotely on the provider’s data center and is delivered and accessed via the internet. In this scenario, the business subscribes to the service instead of making a large investment for their own on-premise PBX infrastructure. This allows the business to access the service from anywhere that has internet, allowing them to connect all their employees and all their locations under one phone system.

If you can see a pattern, each component of a virtual phone service leverages the reach of the internet to give businesses and their users a more flexible and mobile communications solution compared to its traditional counterparts.

More than just a virtual telephone service

So you have learned that the basic virtual phone service leverages virtual phone numbers, VoIP, and cloud PBX as its main components.

RingCentral, however, is more than just your basic virtual phone service. It is a complete, industry-leading communications solution that solves most, if not all, business communications needs.

Aside from the basic functions, RingCentral also provides:

A business SMS and internet faxing service

Aside from voice calls, RingCentral also provides other communication avenues for business and their users. The internet faxing feature lets you and your team send and receive faxes without the need for a fax machine. You can access your faxes through your online account or through the RingCentral app.

The same goes for business SMS. Instead of using your personal phone number to send SMS or MMS to clients and customers, you can instead use your business phone number. This adds credibility to your text message, as it uses a telephone number associated with your company.

An online meetings solution

RingCentral MVP® subscribers will also get an online meetings solution that should solve your business’s need for face-to-face meetings without increasing your travel expenses. Impress your customers and your team with HD-quality video and voice.

The online meetings feature also lets you share your screen with all participants, ensuring that you are all on the same page. If people have no access to their computers, you can also host a teleconference or audio conference that people can join using any phone available to them.

A team collaboration suite

Get more done by improving collaboration within your team. The RingCentral app provides businesses a real-time team messaging app that also allows for quick file sharing and task management. Your team can also instantly set up a video meeting from the app if there is a need for face-to-face conversation.

A unified communications platform

The best part is that all these features can be accessed from a unified platform. RingCentral removes the need to shuffle from one app to another to access all their features. This allows you to seamlessly transition from calls to video meetings and to team messaging without losing track of what you are working on.

Sign up for a RingCentral account now and equip your business with the best virtual phone service and unified communications solution.
