Technology has changed the way we interact with our world and how we communicate. Phone technology is no different. The biggest advance in telecommunications in recent years is the rise in VoIP systems and virtual phone services. This cloud-based tech allows you to make a call anywhere from any device.

The best part of VoIP technology is that you can make and receive calls from any device using a single number. But just what is a voice over internet protocol (VoIP) number, and how does it work?

Don’t worry - we’ve got it all covered for you:

What is a Voice Over IP Number?

Let’s start with the basics: what exactly is a VoIP number? It’s a virtual phone number that is very much a real telephone number assigned to a user. VoIP numbers differ from regular phone numbers in that it isn’t connected to a specific, physical phone line.

Because VoIP numbers aren’t connected to a physical phone line, they can be used by any device that can access the platform that hosts the number. With VoIP providers like 8x8, this can include:

  • An IP phone (like a regular desk phone but for VoIP)
  • A cell phone or other mobile device
  • Desktop computer or laptop

Make phone calls from anywhere

Using a virtual number, you can make non-fixed VoIP calls from anywhere using any of your devices. Your VoIP number isn’t tied to one physical location, so if you have to move to a new location or work from home, nothing changes! Simply use a softphone or appropriate mobile device, and receive business calls as you would in the office.

With VoIP service providers, you can use your number and operate normally no matter where you are. You never have to skip a beat if you need to change your business's normal operations.


With your VoIP service, you can get signed up in minutes, giving you connectivity across the country (or even the world). All you need is a sufficient broadband internet connection to ensure appropriate call quality.

Managing your calls and business has never been easier. You can also easily track analytics connected to each of your business numbers to keep an eye on how your customer support team is performing.


VoIP numbers are there to work for your business, whatever that means. Because it requires no additional equipment or technical expertise to add or remove a line, it can be done with a few clicks of a button.

There are also more features included than with traditional phone systems. This allows you to use a more unified communication strategy that allows more flexibility in your day. For example, business VoIP phone services like 8x8 usually come with features like SMS messaging and video conferencing. You can switch from audio calls to video calls all while sending text messages to your team.

Cost-efficient for most businesses’ phone systems

From flexible pricing plans to affordable phone bills to low maintenance costs, businesses can save money by switching to a VoIP number. You don’t have to pay expensive setup fees, maintenance costs, or buy desk phones. With VoIP numbers, you probably already have what you need to get started.

Also, the portability of your phone number means that you can reduce operating costs by having some level of remote working. With additional features like text messaging, voicemail, and integrations to CRM software, your company will operate more efficiently. All of this helps your bottom line.

Have shared lines

While this is a feature that traditional phone lines can have, VoIP numbers do it better. With traditional lines, you must be in the office to answer the phone. Plus, all phones on shared lines will ring at once.

With VoIP, you can decide what to do with incoming calls on shared lines. Special call routing rules can be set to route calls on a shared line in a specific order to a set group within your team. You can also set it to route to the person best suited to help the caller.

Choose your custom phone number

This is probably one of the greatest features of VoIP numbers. You have the power to choose your own number. Let’s look at some options.

Local area codes

If your business stays within your local area, you may opt for a number with a local area code. A local number may help you to instill trust with your customers. This type of number will also be easier for them to remember.

Toll-free numbers

If your business has a customer base that is regional or even national, you may want to adopt a toll-free number. Toll-free numbers are also familiar to customers and help build your reputation as an established company. These numbers even include toll-free texting.

Vanity numbers

A vanity number is a phone number and a marketing tool in one. Vanity numbers, like 1-800-FLOWERS, use the letters on the phone dial pad to make phone numbers memorable. It makes dialing your number easy for customers.

This feature is available with traditional phone companies, but it’s often extremely costly. With VoIP numbers, even small businesses can be a little vain.

Bring your business phone number with you

Do you already love your phone number? That’s great! You can keep it if you decide to switch to a VoIP network. Porting your existing number to your new service is easy and comes at a low cost. You don’t have to lose anything by switching and you can gain so much.

What do I need to support my VoIP phone system?

You need very little to get calling with your new virtual number. You just need a device capable of making business and personal calls over the internet, a reliable internet connection, and a VoIP carrier.

The first thing you need to consider is the quality of your broadband network. From there, it’s a matter of deciding which are the best devices for you.

Internet connection

In order to make high-quality calls, you need an internet connection. Make sure you:

  1. Check with your VoIP provider to see what speeds their service needs.
  2. Run speed tests with your existing network to ensure you have the minimum required.
  3. If it’s insufficient, check to see if you need to update your router, modem, or cables.
  4. If the problem is with your internet provider, talk to them about increasing your speeds.
  5. If they can’t, shop around for another internet service provider.


With complete business phone systems, you have multiple options that you can choose from when it comes to devices:

IP Phone

An IP phone is an internet phone that disguises itself as a traditional desk phone. It has all the advanced features that come with a VoIP number but suits a workforce that is attached to their desk phones. These types of phones also include conference phones.


Softphones allow you to make and receive internet calls from your number through an application. VoIP services provide call center software and mobile applications that allow you to use your computer, smartphone or tablet to call with your virtual number. That means you don’t have to give out your personal mobile number to make or receive business calls away from your desk.

Existing phones

If you are happy with your hard phones, that’s okay too. All you need is an adapter to use your new VoIP number with your existing desk phones. This gives you easy access to all the advanced features that come with modern telephony’s cloud technology.
