I'm considering 3CX - have heard good things from friend using it. But they don't use branch office. We only have 2 employees, and would consider buying the Small Business Edition for the additional features at our store. I would like to "branch office" link it to my home -- so that I can answer calls and have calls forwarded to me when I'm at home (just like when I'm in the office). I was wondering if I can buy the Small Business Edition and link it to a free edition so that the free edition could be at home. Would that work? If so, would I be able to use the commercial edition features from the free home phone system box linked to the paid commercial "small business" version at the store? I was wondering if I could eliminate phone company lines at home, and make/receive phone calls at home as an extension of the store phone system. Can anyone answer these questions for me and tell me if it would work?
