Pros & Cons from Real Users Pros The platform is very easy to use and devices which you can add makes it very great tool if you on a mobile office or you often not at the desk. Also, for a stationary office work the platform can replace a normal desk phone This software is great for allowing us to communicate internally at no cost. It also has the plus of being the only free solution I’ve found with dial in numbers. Ability to give out RingCentral numbers on cell phones, so users do not need to use their personal number to make contact. Easy design and interface when setting up users and managing teams. Support is very quick to respond. Works great for a small to midsized company and is a valuable asset which will enable them to better handle their call volumes. Has all the features needed with desktop, mobile, and browser capabilities. With click to call from your mobile or browser is a sweet add-on. able to set up simple IVRs for your business needs as well. Cons Using it almost every day, platform itself works perfectly, hence its relies on your connection. The only con is feature limitations, which is to be expected. Service is dependent on the internet, so when traveling down the highway, sometimes a call will drop if you have bad cell reception. End user training is the biggest hurdle I am facing as some are up in age and set in their ways. The only con for the system would be when adding new users and setting up extensions could be confusing at first but after you create a few you will get the hang of it.
