what is a voip number and how does it work?

Whether you’re a business owner, a remote worker, or someone who wants to stay connected, a VoIP number might just be the communication upgrade you’ve been waiting for.

It’s like a regular business phone number that works over the internet, giving you flexibility and savings that traditional landline phones just can’t match.

Let’s look at what is a VoIP number and how you can get one. We’ll also discuss how to get a cloud VoIP service started and several easy ways to protect your business phone numbers from fraud, too.

What Is a VoIP Number?

A VoIP number is a real telephone number operating on an internet connection. Voice over IP phone numbers are assigned to a user and not to a physical location. This means you can use your VoIP number anywhere via a VoIP phone app that works on any mobile device or desktop computer.

The best part about a VoIP phone number is you aren’t bound to a specific desk to take phone calls — you can take or make calls anywhere using your VoIP number. 

Cloud-based VoIP technology lets you call from anywhere using an app on your mobile phone, computer, laptop, or desk phone using the same number without needing a physical private branch exchange (PBX).

How Do VoIP Numbers Work?

VoIP works by placing calls over the internet rather than copper wires used by the public switched telephone network (PSTN). Unlike traditional phone service, where phone calls must be routed through the local telephone company, VoIP phone service uses any broadband connection. With this method, VoIP routes a call along the most efficient path.

VoIP also extends to other forms of communication, like chat and SMS messaging. A business owner can select VoIP phone numbers for its staff, even if they work remotely. With VoIP, a traditional phone line becomes obsolete for both business and residential use.

Give your phone number superpowers. Seriously.

Types of VoIP Numbers

VoIP technology offers different phone number options with specific features and purposes in mind.

1. Local numbers

Local VoIP numbers are associated with specific geographic areas, usually a city or region. They use familiar area codes, creating a sense of local presence, even if the business isn’t physically located there. This builds trust and credibility, particularly in markets where customers prefer dealing with local companies and work well for small businesses.

2. Toll-free numbers

Recognizable by area codes like 800 or 888, toll-free numbers allow customers to call without incurring charges. They’re ideal for customer service, sales, and national businesses. Toll-free numbers also convey a sense of professionalism and accessibility.

3. Vanity numbers

Vanity numbers are customized spellings, often using words or phrases related to the business (e.g., 1-800-FLOWERS). These numbers are easy to remember and great for marketing, particularly in radio or TV ads. While potentially pricier, their memorability can significantly enhance brand recognition.

4. Direct inward dialing (DID) numbers

DID numbers enable direct connections to specific extensions within an organization, bypassing main reception. These numbers streamline communication in large companies, reducing receptionist workload and caller wait times. DID also benefits remote workers, making them appear part of the main office system.

5. Virtual numbers

Unbound by location or device, virtual phone numbers can be forwarded to any phone or device. This flexibility is perfect for remote workers, freelancers, or businesses with a distributed workforce. Professionals can maintain a consistent number regardless of their physical location.

6. International numbers

These are local numbers in foreign countries, enabling businesses to establish a virtual presence abroad. Customers are charged at local rates, making it more likely they’ll call. International calling builds trust and accessibility for businesses with a global customer base.

7. Ported numbers

Ported numbers are existing numbers transferred from a traditional phone service or another VoIP provider. They work best for businesses with established brand recognition tied to their number. You can easily transition to VoIP without losing customer connections.

Choosing the right VoIP number type depends on your target audience, business size, geographic scope, and branding. Selecting the right combination helps businesses create a communication system that’s flexible, efficient, and customer-centric.

VoIP Phones vs. Landlines

The mode of transmission between the two technologies is not the same. A VoIP phone number does not get assigned to a location, while a regular phone number does.

Also, the underlying technologies are dramatically different. A standard landline number travels through copper phone lines. A VoIP number utilizes data networks, such as the internet and internal enterprise LANs (Local Area Networks), to make voice calls.

These advanced features collectively make VoIP numbers a versatile and powerful communication solution. You get better flexibility, control, and advanced capabilities to stay connected in a digital-first world.

How Do I Get a VoIP Number?

Getting a VoIP number is straightforward and surprisingly affordable. Here’s a breakdown of the steps involved:

How to get a VoIP phone

You can get a VoIP phone number from VoIP service providers that offer VoIP service plans. Most plans are less expensive than a cellphone or regular telephone service. As a result, you can lower your costs by up to 60% and access many more features that only VoIP can provide.

If you have existing phone numbers that you’d like to keep, you can port them to your new VoIP service. This process allows you to maintain your current number while enjoying the benefits of VoIP. If you prefer, you can also choose a new local or toll-free VoIP number from your VoIP provider.

Nextiva offers seamless number porting and setup at no extra charge on all their plans. The business phone service plans start at an affordable $20/month, making it a cost-effective option. You can port phone numbers from your cell phone, Google Voice, cable/telephone company, and even a competitive VoIP service provider.

Setting up a VoIP phone number

Once you’ve chosen your VoIP provider and plan, you can typically start using your VoIP system on your computer or smartphone right away.

The provider’s setup process will guide you through configuring your account, selecting your number(s), and customizing your settings. With VoIP, you can enjoy significant cost savings compared to traditional phone services while accessing a wealth of advanced features that enhance your communication capabilities.

Why Should I Get a VoIP Number?

VoIP phone systems offer numerous advantages over traditional phone services. You’ll enjoy cost savings, enhanced flexibility, improved reliability, crystal-clear call quality, and a host of other benefits.

Lower cost

VoIP numbers use your internet connection, eliminating the need for a dedicated phone line. Even with monthly service fees, the overall cost is lower than maintaining a traditional system.

Most VoIP plans include valuable features at no additional charge, such as auto-attendant, call queuing, intelligent call forwarding, and one-click conference calls. You can even get a toll-free number included.

More accessible

A VoIP phone system doesn’t rely on a physical location; all you need is a stable internet connection. This enables communication across the country or even globally. VoIP calls use minimal bandwidth, so even a modest 10MB connection can handle numerous calls simultaneously.

You can reliably use your smartphone and mobile apps to make and receive calls with LTE technology. Wired connections are ideal, but a strong Wi-Fi signal works well too.

More flexible

VoIP networks are highly scalable. Unlike traditional systems, you can easily add multiple phones without limitations, as long as your bandwidth allows.

VoIP numbers work on various devices, including computers, tablets, and dedicated VoIP phones. Many VoIP phones offer accessories like headsets for added convenience. You can even use traditional phones with an Analog Telephone Adapter (ATA).

Better voice quality

VoIP uses advanced sound compression (codecs) to deliver HD call quality, eliminating fuzziness and static. The G.722 codec offers twice the bandwidth of analog calls, ensuring clarity.

In rare cases of limited bandwidth, the call quality gracefully adjusts without any action on your part. Calls to traditional phones still sound great, though they may not be in full HD.

Multiple devices

Use a single virtual number across multiple devices. Log in to your account on any VoIP-compatible device — laptop, computer, or smartphone — to make and receive calls. It’s that simple.

You can also set up call forwarding to other numbers for added flexibility and configure call routing to meet your needs, such as having all or some phones ring simultaneously for a sales team.

Choice of area codes

Businesses can choose an area code outside their location to establish a local presence in different regions, which builds trust and credibility with customers.

You can also have multiple local numbers route to one location, which is helpful for businesses with multiple branches, making calls from any area code without incurring long-distance charges.

Number portability

There’s no need to change your existing phone number when switching to VoIP. This saves you the hassle of updating your website, business cards, and marketing materials.

Port your old number and continue business as usual, regardless of your location, as long as you have a reliable internet connection.

Toll-free numbers

Toll-free numbers are no longer exclusive to large enterprises. Small and medium-sized businesses can now use them affordably through VoIP, often at no extra charge or a minimal fee.

Toll-free numbers eliminate the perception of being limited to a single geographic area, making your business appear more accessible and national. You can easily receive toll-free calls on your phone or computer, thanks to the flexibility of VoIP and its ability to ring multiple devices simultaneously.

How To Protect Against VoIP Threats

Even though VoIP technology is easy to use and inexpensive to maintain, this modern-day business phone solution is not immune to fraud.

The problem with these kinds of VoIP number tricks is the difficulty in tracing the call. If you do not know what to look for or expect from a VoIP scammer, you too may become a victim of VoIP fraud.

Look for a VoIP provider that provides network-level security through TLS and SRTP. This provides you the maximum privacy and performance in every VoIP call. Nextiva offers this built-in call encryption, so be sure to ask about it.

What is vishing (VoIP phishing)?

Known as “voice phishing” or “VoIP phishing,” it’s a type of phone scam. The fraud begins with the appearance of a real caller ID displayed with a valid telephone number from a recognized and trusted source.

Then the scammer attempts to convince the unsuspecting individual to disclose critical personal data and financial information.

Often, the callers will prey on two key factors to gain the information they need: a person’s fear and financial stability. This scam is more successful because people generally trust caller ID without knowing it can be faked.

Protecting against VoIP attacks

VoIP phone fraud attacks are sophisticated, which makes it challenging to recognize legitimate calls and attempts at identity theft. Below are a few tips you can develop to protect yourself from these intrusions:

The good news is that successful VoIP fraud attacks are rare. You must be vigilant against the threat; otherwise, you could inadvertently leak your customer list.
