Best Business Phone Systems: 35+ Tools to Keep You Smilin’ and Dialin’

As you likely know by now, there’s no one-size-fits-all when it comes to any type of technology. VoIP providers are no exception. We’ve thoroughly researched the best business phone systems in the market today and narrowed it down to the top 35+ here.

There are several things that are crucial to any successful business. Today’s companies need internet access and devices to connect, whether those are smartphones, tablets, desktops, or laptops.

They also need at least one ambitious, forward-thinking leader to move things forward. Innovative leaders even know how to find the most affordable services without compromising on quality and customer service.

Technology continues to change. Once, the office phone system was a given. Now, organizations rely on WiFi calling and VoIP as well.

Regardless of the technology, though, every business needs an effective way to make voice calls. And it’s no longer sufficient to have desk phones that only make phone calls. Today’s businesses need phones that can easily handle video conferences, multiple-party audio conference calls, inter-office chat, and more.

For that reason, most modern-day businesses turn to Voice Over Internet Protocol (VoIP) phone systems for their audio communication needs.

Available for a low monthly fee, these setups mean that companies can get a new system in place quickly and add and remove employee access as needed. It also means they have a wide variety of tools at their disposal, depending on the provider they choose.

How to Choose the Best Business Phone Systems

You may think VoIP call quality is the most important factor in choosing the best business phone system.

While that’s certainly important, you need to look for the best VoIP features in potential vendors. The providers we’ve listed as the best demonstrate a dedication to equipping businesses with the tools they need to collaborate, communicate with clients, and move their companies to the next level.

Top Providers

To arrive at this list, we looked closely at a wide range of solutions, from those serving enterprise-level organizations to those that target small startups.

We’ve weighed all providers using data like:

  • Pricing
  • Customer service
  • Built-in collaboration tools
  • Integrations with popular business solutions

Even with all of those considerations, though, chances are there are features that are more important to your own unique environment than others, so it’s important to consider those as you look through this list.
