I HIGHLY recommend it to everyone I meet!

I have tested and used almost every other virtual/voip phone system on the market. While most of them cost an arm and a leg, they are also a total mess. The UI is so overwhelming and cluttered. OpenPhone has really disrupted this by creating an affordable and super clean phone system for individuals and teams. I HIGHLY recommend it to everyone I meet!
