Wayne: I've not started using either yet but I had narrowed it down to those two. Was originally leaning towards Ring Central but now am about to start with Onebox. It is the 2000 minutes that convinced me. I may need more than 4 "extensions" but it is less expensive to add one for 11.99 than to get more upfront with RingCentral but fewer minutes. I'm thinking all my calls will be channeled through this to reduce (or nearly eliminate) the receptionist time on the phone- so we need enough minutes. One area of concern I learned about today however, is that they don't have support available after hours or weekends. I would hate to have a glitch and not be able to troubleshoot it after hours.
