Ooma Office is a business phone system which is designed to be easy to use and quick to install. The maximum number of users the system can have is 20. This system boasts all of features you'd expect for an enterprise system, but it is built for small companies. In 2015, Ooma Office was elected to the San Francisco Business Times Fast 100 and in 2014 was chosen as PCMag's Business Choice award winner.
