What is a VoIP Number, How Does it Work & How Do You Get One?

Sections of this topic

    Voice over Internet Protocol, or VoIP technology, allows you to make and receive calls over the internet. Although the technology has been around for some time, VoIP has never been as popular in the business world as it is today.

    The VoIP global market size was just over $30bn in 2020. According to a VoIP industry analysis by Global Market Insights, the global VoIP market is projected to hit $95bn by 2027 as more and more SMBs move toward this technology. If you’re thinking about getting a VoIP number for your business, here’s all you need to know about what it is, how it works, and where to get one. 

    What is a VoIP Number?

    A VoIP number appears and functions just like a regular 10-digit telephone number. The primary difference is the mode of transmission. While traditional landline numbers use a network of telephone lines, VoIP uses the internet to place calls. 

    When you use a VoIP number to call someone, it appears like any other phone number to the receiver. This means they won’t be able to tell the call isn’t coming from an actual landline. 

    Unlike traditional phone numbers, a VoIP number isn’t assigned to a specific device, location, or phone line. Instead, it’s assigned to a person. This person can use their VoIP phone number to place a call from anywhere as long as they have an internet-enabled device. 

    Since Voice over Internet Protocol isn’t location-specific, you can get the area code of your choice. This saves long-distance fees for callers. Getting a VoIP number is recommended for companies operating across the US.

    How Does a VoIP Phone Number Work?

    As mentioned above, VoIP technology works over the internet. It doesn’t need copper wire telephone lines to facilitate communication. 

    Landline numbers use analog signals to transmit voice. When you place a call with a VoIP number, your voice and data are converted into digital signals before they’re transmitted over the internet. If you call a regular landline, the digital signals are converted back into analog before they reach the receiver.

    Using this technology, you can make and receive calls on your virtual number no matter where you are. All you need is an internet connection and an internet-enabled device such as a smartphone, computer, or tablet. Apart from voice calls, VoIP also supports text messaging and video calls if the receiver is using VoIP too. 

    Different Ways for Using a VoIP Number

    You can make VoIP calls using three different methods. These include using an analog telephone adaptor, using an IP phone, or availing of the services of a VoIP caller.

    Use an Analog Telephone Adapter on a Regular Phone

    This method lets you use VoIP technology without fully switching from traditional to VoIP. Plug an Analog Telephone Adaptor into your traditional landline phone to connect it to the internet. 

    Use an IP Phone

    Alternatively, you can get an IP phone. This is just like a standard telephone, but it comes with Ethernet ports to connect it with an internet router. These phones have built-in hardware and software to make and receive VoIP calls.

    Use a VoIP Service Provider

    If you want to make VoIP calls, signing up with a VoIP service provider, also known as a VoIP caller, is by far the most convenient and cost-effective solution. All you need to do is sign up, download and install the software, and start making Voice over IP calls from your computer or mobile phone. 

    If you go for a VoIP service, you don’t need to get any extra hardware as long as you’ve got functional speakers and a microphone. Let’s discover more about how to get a VoIP number from a service provider. 

    How to Get a VoIP Phone Number?

Still, here’s an overview of what you should expect when you go with a VoIP phone number service.

    Step 2: Select a VoIP Plan

    Different service providers offer different plans. Choose the one that suits your needs best and fits your budget. Remember that not all service providers offer the same kind of plans. So choose your service provider in accordance with your business type, size, and VoIP needs.

    Your VoIP service provider will have an interface that facilitates selecting and purchasing a VoIP number. This is a fairly straightforward process but may vary between services. Most providers let you choose your area code to make it easier for customers from a specific area to contact you. 

    That said, you can also choose to port your existing telephone number to VoIP. To do so, you’d have to contact your previous phone provider to transfer it. This may take a few business days. 

    Step 4: Complete Setup

    Once you have your VoIP phone number, all you need to do is set up the hardware and software to start making calls over the internet. The cheapest and most convenient way to go about this is simply to use your computer and mobile phones for VoIP calls. If you want to connect office phones to the system, you might need to buy some additional hardware.

    Gives You Choice of Area Codes

    Unlike traditional phone numbers, you can freely choose your area code with a VoIP service. You don’t have to be in a state to use its area code for your business phone number.
