Ring Central is a very robust system and I like how they can easily get you an auto attendant which other companies cannot do this as easily. I also liked their integration with smart phones, internet faxing, and the fact you can get toll free phone numbers. The system the developed is pretty good. The only downside I think is the way they price it per user. The only plan that often makes sense for a business is one that has unlimited minutes and that comes at $49/month which is extremely expensive, especially when you consider the alternative options like google voice. Anyone interested in this service should also check out google voice and see if that almost free option fits their needs. I still like ring central but we cannot begin to afford their service.
