It also offers several valuable supervisor tools, including the ability to listen in on agent calls.

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.

We ultimately settled on the following 19 phone systems to consider as best picks: 8×8, AT&T, Avaya, Booth, Cisco, Dialpad, ESI, Fonality, FreedomVoice, Grasshopper, Jive, Mitel, Nextiva, Ooma Office,, RingCentral, ShoreTel, Toshiba and Vonage. (See full list of business phone systems and their websites below.)

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 offered its users. Finally, we considered the pricing that was available on these services’ websites or what was quoted to us during customer service calls.

Our process involves putting ourselves in the mindset of a small business owner and gathering the data that would be readily available to such an individual. We perform all of our research by visiting company websites, making calls to customer service departments and interviewing real users.

We analyzed each system based on the following factors:

  • Deployment options
  • Level of service
  • Reliability
  • Customer service
  • Calling features
  • Collaboration tools
  • Mobility options
  • Cost
