What is a VoIP number?
A Voice over Internet Protocol (VoIP) number is a virtual phone number that’s not associated with a specific location or device.
Rather than relying on the traditional landline network for calling, VoIP phone numbers are those that utilize internet phone service. That’s why they’re also sometimes called internet phone numbers.
From a user’s point of view, a VoIP phone number isn’t much different to a traditional one. It’s a string of digits you use to make sure you call the right person. Rather than getting one when you have a new landline installed, you get your IP phone number when you sign up for a virtual phone service from a provider like RingCentral.

The different types of VoIP number
VoIP numbers, then, are distinct from traditional numbers due to the technology behind them. As a business, however, you can still get the three main types of phone numbers that you may need:
Local VoIP numbers
Local numbers start with an area code which denotes a specific geographical region. They can be very important to businesses that want to establish a presence in particular places. Customers—existing and potential—are generally more likely to answer calls from numbers they recognize.
VoIP providers often offer a wide range of different local VoIP numbers for business—RingCentral has more than 200 area codes for you to choose from.
The big advantage of the VoIP-based version of these numbers is that you can get and use whichever ones you like, without having to have a physical presence in its geographic area.

Toll-free VoIP numbers
You want to show customers that you care about them and are available to help whenever they need it. Toll-free numbers are a great way to do that, by making it free for those customers to reach out to your business.
As long as your chosen VoIP provider is a Responsible Organization as designated by the FCC, it should be able to offer your toll-free VoIP numbers.
Attaching toll-free numbers to a virtual phone system can improve your accessibility to customers in an additional way, too. Those numbers can be used to make and take calls on virtually any device, virtually anywhere. Thus, the use of the numbers isn’t only limited to when you have staff in the office.

Vanity VoIP numbers
A vanity number is a customized phone number that’s used to strengthen your company branding. Typically, they use a combination of numbers and letters to create a memorable impression—think something like; 1-800-FLOWERS.
Subject to the availability of your chosen number, RingCentral makes it easy to get a vanity VoIP number. A RingEX subscriber can simply pay a one-off $30 setup fee and then add an additional $4.99 per month to their subscription.
How does VoIP work?
As mentioned, a VoIP phone number doesn’t rely on traditional landlines or even the cellular network. Instead, internet calling relies on VoIP technology.
In the simplest possible terms, when making a VoIP call, your voice is transformed into digital data packets. These packets are then transported via the internet to the designated endpoint—defined by the VoIP phone number you’re calling. Once there, they’re transformed back into audio.
This all happens instantaneously, meaning that participants in a call will likely not be able to tell the difference between traditional and a VoIP call.

VoIP vs landlines: key differences
VoIP and landlines both let you make and receive phone calls, but that’s where the similarities end. Here are some of the main differences:
VoIP lets you call from anywhere. . .
With a traditional landline, your phone number is tied to a physical location. Because VoIP calls take place via the internet, you can connect to your account and use your VoIP number from anywhere in the world, as long as it has an internet connection.
. . . on any device
Landlines are plugged into the PSTN with actual copper wires, so you can only make and receive calls on devices that are attached to that landline. But with VoIP, you can use mobile phones, tablets, laptops, computers. . . or stick with desk phones if you want to.
VoIP doesn’t require hardware
As we said, there are no physical wires involved with VoIP. And your vendor looks after all the necessary hardware (such as servers) at their end, so you don’t have to find room for it on your premises. In fact, you don’t even have to have premises—you could operate entirely remotely.
VoIP saves you money
With no hardware to install or maintain, and the flexibility to work from anywhere, you can reduce your overheads. You’ll just pay a monthly subscription for the software.
Calling is cheaper over the internet, too, including international calls. Plus, if your VoIP number is part of a unified communications package like those offered by RingCentral, you can make savings through improved productivity.
VoIP is the future
Savvy businesses are choosing to make the switch to VoIP numbers, but soon there won’t be any choice in the matter because landlines are being phased out.
The Federal Communications Commission (FCC) deregulated copper landlines back in 2022, meaning US telecom companies don’t have to offer them anymore.
How to get a VoIP number
So, you’ve decided that VoIP will be great for your business (we agree). Fortunately, it’s surprisingly easy to get a VoIP number. Most of the heavy lifting will be done by your chosen VoIP provider, once you’ve signed up.
When you subscribe to a pricing plan with RingCentral, for example, you’ll be asked what type of VoIP number you need. You’ll then get a choice from the available local, toll-free, and other numbers and all the help you need to get set up.
Before you take the plunge, though, it’s worth making sure that your current infrastructure can handle the deployment. Things to think about include:
Before opting for a virtual phone service and accompanying internet phone number, you should also check on your network equipment.
Outdated routers and switches can impact the performance of a VoIP-based telephone system. A reliable router is important in keeping a stable network environment while a dedicated switch is needed to ensure that the router can handle your required bandwidth.

If you’re going to stick with physical hardware—rather than softphones on your PCs or mobile devices—if possible, connect those VoIP devices to an
Ethernet connection.
You may need to invest in a Power over Ethernet (PoE) switch, which delivers power and voice/data over the same wire. What you get is an efficient power provision to every PoE-enabled device, such as a VoIP phone.
With PoE, there is no need to have a dedicated AC outlet or power cabling for each device. At the same time, it allows these devices to connect to an uninterruptible power supply (UPS), which would continue to deliver power to the system in the event of a power blackout.

The business benefits of VoIP numbers
A VoIP number may look and work like a regular number to an end user, but they open up a world of possibilities traditional landline numbers cannot offer.
Here are just a few of the advantages of using a VoIP number for business:

There was a time when only large enterprises could afford toll-free numbers, but this changed along with a few advances in technology. Now, even small- and medium-sized businesses (SMB) can use a toll-free number so customers from anywhere in the US can call them without spending a dime.
You don’t want your customers to shell out money every time they contact you, right? If someone has an issue about one of your products, they can easily get in touch with your company and raise their concerns. Knowing you’re always a phone call away builds trust and loyalty among your customers.
Depending on your service provider, you can choose from a variety of toll-free VoIP business phone numbers, including the popular 800 number prefix. If you wish, you can opt for a custom vanity phone number—you can request for a sequence of numbers that is easy to recall (e.g., 1-800-NYC-ROOFS) and makes for some solid company branding.

VoIP allows sharing a phone number across multiple devices. Calls made to that number can be answered from any other device that uses the same number, thereby eliminating missed calls from customers and the need for call transfers.
This is particularly helpful for retail businesses and restaurant chains where customer service is of supreme importance. You can leverage this feature with the RingCentral VoIP phone system.

The VoIP number assigned to your business is geographically flexible (e.g., you can carry it and access your account anywhere you go). So, if you have to move to a new location, you don’t have to ask the phone company to move your line to the new address—if it’s even possible—as with traditional landlines.
With VoIP, you can retain your existing number and operate as usual when your business relocates. This saves you unnecessary downtime from installing a phone line and costs that come with updating marketing materials like websites, brochures, and business cards.

There aren’t many things more convenient than being able to contact anyone across the country or anywhere in the world at any time, using any device. That’s because of the fact that VoIP only requires a stable internet connection to make a call. As such, managing calls and business numbers is also easier.

Your communications infrastructure should scale as your business grows and add more users. In a traditional phone system, this could mean purchasing new servers and wiring systems—but not when you’re using a VoIP number.
In a VoIP network, your capacity to add new users is only limited by your bandwidth, which, of course, can be expanded according to your requirements. You can add or reduce bandwidth as the need arises.
Often, your employees will need to move between devices to finish tasks. They could go from office to field and start where they left off if they have a smartphone on hand. With VoIP, it’s easier for your employees to catch up on their tasks even outside of the office.

VoIP number challenges: Protecting your business from VoIP fraud
While the business benefits of VoIP numbers should by now be clear, it’s important to also consider one notable challenge associated with them. That being that they have been used by malicious actors for a type of fraud known as “Vishing” or “VoIP phishing”.
What is vishing and how do you protect yourself against it?
Like its email counterpart, VoIP phishing involves someone fraudulently pretending to be somebody else. Rather than sending an email from an account claiming to be legitimate, Vishing sees fraudsters make calls that appear to have a valid caller ID and come from a genuine number.
The fraudulent caller then tries to convince their victim to disclose personal details or—often—financial information. It’s a dangerous type of fraud as people are often unaware that the phone numbers and caller IDs which appear on their phones could be manipulated.
Given that, to protect yourself and your business, it’s a good idea to follow these best practices to combat potential VoIP fraud and other phone-based security risks:
- Don’t automatically assume that a caller is who their number or caller ID claims them to be. If an institution like a bank or a trusted organization calls you out of the blue, it pays to be skeptical.
- Never give out confidential information in response to an inbound call. Banks and other financial institutions may sometimes call you. They won’t ever, however, require you to provide confidential details. If someone does ask for such information, refuse to provide it.
- Change any login details for devices, software, and systems regularly. And, use unique logins for each.
- Never call phone numbers provided in unsolicited emails—even if you think you recognize the sender.
A VoIP number: your business’s ticket to the future
For a forward-looking company, it pays to have a concrete growth plan that will guide your organization toward reaching your targets.
Will you be having additional employees over the next three years? How many are you expecting? Is that store expansion plan that’s previously been shelved finally pushing through? The answers to these questions will help you determine the ideal components of your VoIP phone service..

VoIP number FAQs
Any new technology introduced to an existing system will give rise to questions, no matter how simple it may be. Expect your employees to ask what devices they can use their business VoIP number on, how to send a virtual fax, or how to access voicemail.
You can get everyone up to speed in no time, however, by preparing a handy guide or by creating a slideshow explaining VoIP’s features and functions (which really doesn’t take much to absorb).
Knowing how certain tools make their tasks easier helps keep your employees engaged. You could have access to the most advanced technologies, but if your employees aren’t receptive to them, you aren’t hitting the mark.

Now that you have the system in place, it’s time for a test run. Be sure to allot enough time to run through your new VoIP system so you can identify any issues up front and address them immediately. Consider testing for the quality of VoIP calls at separate times throughout the day to simulate real-world usage.
For example, if you discover that upgrading your internet service is necessary, do it right away. If you keep hearing echoes in every call, perhaps the wires are too long, and this could be causing the voice quality problem. Or, maybe all you need to do is move your router away from the computer monitor.
After a string of test calls, contact your provider to get a mean opinion score (MOS), which is a measure of quality and fidelity of voice calls. It isn’t uncommon for your MOS score to decrease as network traffic increases.
Implementing a VoIP phone system will help you and your employees communicate better within and outside your company. Rest assured that RingCentral will guide you every step of the way to ensure a smooth migration and a consistent experience.

Yes, it is possible to text VoIP numbers, just like you can text traditional mobile numbers. In fact, with the right VoIP provider, business text messaging is a key feature.
For example, RingCentral RingEX users can use a single business number to call, text, fax, and more. As well as taking calls, receiving texts and faxes, too. This is just one way that a unified communications platform can help businesses keep communications better organized.

Before you move your business over to VoIP, it’s wise to consider security. In many ways, VoIP is safer than landlines—calls aren’t routed through the public switched telephone network (PSTN), so there’s less risk of eavesdropping or interception.
Look for a VoIP number vendor with top-notch security. For instance, RingCentral offers enterprise-grade security protocols in the shape of TLS authentication and SRTP encryption. It continuously monitors systems to spot anomalies and prevent data breaches, fraud, and service hijacking.
You also have to be vigilant against digital phone fraud such as vishing (“voice phishing” or “VoIP phishing”). Scammers display a caller ID that appears to come from a trustworthy source, with the aim of getting you to reveal personal or financial details.
It’s important to keep up-to-date on the latest scams, and train all employees on how to spot them. Change your login details for all devices regularly. Never give out private information over the phone unless you have initiated the call. If you’re not sure who’s calling, let it go to voicemail.

If you’re switching from a traditional phone system to VoIP, you can still keep your existing number. Most VoIP providers allow for “number porting” which is the process of switching those existing numbers over to the new system.
When you choose a new phone system provider, it’s always worth discussing porting with them, as the process can differ. In general, however, you shouldn’t cancel an existing agreement related to a phone number you wish to keep until after you’ve initiated the porting process.
As long as you follow the advice of your new VoIP provider, you should be able to keep those numbers that customers already know and trust.
There’s no reason why a customer calling your business or taking a call from your business should realize that you use VoIP numbers. The process of using the numbers and the call quality involved is indistinguishable from other numbers.
Even if they do discover you’re using VoIP numbers, however, all they’re discovering is that your business is at the forefront of telephony technology.

Yes, absolutely. If your business invests in and sets up a VoIP-based phone system, you can get multiple VoIP numbers. Depending on your business needs, these may be a combination of local, international, toll-free, and vanity numbers.
You can even set up unique numbers for separate departments and individuals. Whatever best suits your needs, VoIP systems provide the flexibility you require. With RingEX, you get a dedicated phone number for each user at no additional cost. You can then add additional numbers for affordable monthly prices.
