7 VoIP Business Phone Systems with the Best Mobile Apps


Once, business communication required that you be in the office. Even once cell phones became more common, you really wanted a landline for the best clarity and connectivity. Those days are long gone.

Today, business communication doesn’t have to take place within an office and even conference calls can happen on the go thanks to mobile technology. Here are a few interesting insights that illustrate just how important phone-based communications remain today when employees and even CEOs are increasingly on the go.

  • According to RingCentral, 64.8% of employees use a mobile phone with a business number and only a little over half of all companies even have legacy phone systems for on-premises use.
  • Masergy points out that improved flexibility and increased communication quality are driving factors in the push toward cloud-based, mobile communications.
  • The US BLS highlights that 26 million Americans work remotely and rely on apps for communication.

How does VoIP fit into the mobile connectivity picture? The answer is that some forward-thinking VoIP companies now offer access to most or even all of their features through mobile apps that work right on your team’s smartphones and tablets. That opens up entirely new worlds of communication and productivity.

What is VoIP?

Not sure what VoIP is? Just in case you haven’t kept up with communications technology, it stands for “voice over Internet protocol”. VoIP business phones let you tap into your high-speed Internet connection to communicate, rather than relying on traditional telephone lines. And in most cases, you’ll find that the costs are far less than paying a phone provider, too.

Of course, there’s no shortage of VoIP providers today. You have industry mainstays, newcomers to the segment, trending companies, and more. How do you go about choosing the right one for your needs?

Well, it’s pretty simple, at least initially. Not all VoIP companies offer mobile apps, so if you need that type of connectivity, you can immediately cross any companies that don’t offer it off your list. We do realize that comparing both mobile app capabilities and VoIP provider benefits can be time-consuming, so we’ve ranked the seven VoIP business phones with the best mobile apps for you.

Before we dive into the list, let’s talk a little about what these apps offer, and what they should offer if you’re going to consider using them. Although there is no hard-and-fast list of rules because every business has different needs, these guidelines should help just about everyone. 

What to look for in the mobile apps you use

When it comes to VoIP, the considerations of what you want in an app aren’t much different than the other tools that you use — convenience, ease of use, access to plenty of features, and so forth. You’ll want to consider the apps below, as well as any others on your radar, and take the time to see what you’re getting for the money.

  • Available support: The last thing that you want is a service provider who isn’t available when you need them.
  • Operating system: Know whether the platform offers apps for iOS or Android devices, or both, as well as what you need to support your team.
  • Trial: A free trial allows you to put the app through its paces and find out how it works for your needs without having to commit.
  • Integration: Your team uses a wide range of other software and apps. Make sure the VoIP platform you choose integrates with your technology stack.
  • App-only: Is the VoIP platform app-only? Does it offer both traditional communications capabilities and mobile options?

There’s no “right” or “wrong” choice here; it’s about what’s best for your business. Now that you know more about what to look for, it will be easier for you to review the apps below and what they have to offer. Take the time to explore all the options, take advantage of the trials, and you’ll see that VoIP is going to change the way you communicate for the better in more ways than you anticipated.
