Not Scalable, Don't expect rapid support help.

We have been using RC for many years now, the initial setup was very difficult, making sure the lines rang in the right Extensions, Desk-phones, etc. This system is not scalable. If you have a company with many employees and you want all the outside calls to show the same caller ID, look somewhere else for service, you can't do this with RC. Getting someone in tech support is really difficult, the voice prompt system is terrible, and don't forget your six-digit pin for checking the voicemail because you will go in circles and be unable to bypass the "pin" requirement to speak with someone, in fact, is like they really don't want you to speak with someone, once you have someone in the line they are nice and try to help you. The new desktop app is glitchy, I get missed call notifications after a couple of hours, We have to download images before we can just print or print to PDF, sometimes this creates the app to freeze. Lastly, I write a lot in Spanish to Spanish-speaking clients, I can't write the letter "ñ", No Bueno. You Can't save contacts across all users, each user has to save their own contact, and they do not sync.
