lit of the best VoIP phone

Voice over internet protocol (VoIP) is the future of business communications. A VoIP phone, or IP phone, relies on VoIP technology to send calls as a digital signal over the internet, rather than a physical phone line. It provides the connectivity, agility, and mobility that modern companies need. That’s why so many of them are ditching traditional landlines in favour of a VoIP phone system.

While you could choose a softphone that can be installed on a device to make telephone calls over the internet, having dedicated hardware for your VoIP phone comes with many benefits. There are a lot of VoIP desk and office phone options out there. They offer traditional phone services, as well as a variety of additional features. Some will be perfect for certain businesses and not quite right for others. We’ve put together this list of the best VoIP phones of 2020 to ensure you get the right ones for you.

What to Look For in VoIP Home and Business Phones

Before we get to our 10 best VoIP phones, it’s important to discuss how to evaluate the different options. A VoIP phone system allows you to use a standard desk phone to make calls via your internet connection. Some VoIP systems rely on ethernet connections, but many will work with Wi-Fi too.

That means that VoIP phones can do things traditional landlines can’t, like video conferencing or advanced call handling. As such, your choice of VoIP phones for your business is critical. When assessing the alternatives, there are a few critical criteria to look out for:

  • Price

Is the model of the phone something that fits within your business’s budget? There’s no benefit in splashing out on a top-of-the-range desk phone that you can’t afford, especially if you only need the basic functionality of VoIP calls. When comparing prices of the best VoIP telephones, you should be thinking of value, not cost. Keep the following criteria in mind when deciding if a price represents value for money.

  • Audio Quality & Reliability

It’s not just your internet connection that can affect call quality. A phone designed with audio clarity and quality in mind can make a real difference. Ideally, you want your chosen model to offer HD voice quality. You also need it to maintain that quality indefinitely. 

  • Connectivity

VoIP is all about improved connectivity. That’s also a key factor when choosing a VoIP phone for your workplace. Phones which offer Wi-Fi connectivity are really handy – especially if you’re looking at cordless phones. They don’t require you to connect them up to your router via Ethernet. Models with built-in Bluetooth are great, too. They let your staff use hands-free headsets instead of handsets, giving them all the benefits of a mobile device.

  • Features

The best VoIP phones offer much more to a company than a traditional desk phone. You should be able to route, block, and hold conference calls with ease with your chosen model. What’s more, video compatibility is also a definite bonus. Current internet connections make video conferencing more reliable a tool than ever before. 

  • VoIP Service Compatibility

Most modern VoIP phones are compatible with all VoIP software. It’s still worth keeping in mind, however, that some VoIP providers or services do require certain models of phone.

They’re the main things to keep in mind when choosing a VoIP phone for your business. They’re also the major criteria we used when drawing up our list of the ten best VoIP phones on the market. Below you’ll find a brief guide to each of them, pointing out why they might be exactly the model you’re looking for.
