Our Methodology

To help you find the right Business Phone Systems, we researched and analyzed dozens of options. Here is a roundup of our 2018 best picks for Business Phone Systems and an explanation of how we chose them.

Locating the Best Services

To determine the best business phone systems, we started by listing all of the vendors that have good reputations online (i.e., services that other websites favorably and consistently reviewed). Then, we interviewed small business owners to discover new systems to add to our list.

Choosing the Best Services

We ultimately settled on the following 18 phone systems to consider as best picks: 8x8, AT&T, Avaya, Booth, Cisco, Dialpad, ESI, FreedomVoice, Grasshopper, Jive, Mitel, NetFortris, Nextiva, Ooma Office, Phone.com, RingCentral, Toshiba and Vonage. (See our full list of business phone systems and their websites below.)

Researching Each Service

Next, we researched each provider by investigating its services, watching tutorials and how-to videos, and reading user comments. We also contacted each company's customer service department and posed as business owners to gauge the type of support each provider offers its users. Finally, we considered the pricing that was viewable on these services' websites or what was quoted to us during customer service calls.
