Does anyone know phone systems?
 

I have a mainstream business that I have been using hostednumbers.com to forward the calls. Does anyone know where to get an advanced phone system that will allow me to have multiple numbers and tell me which # is being called as well as forward to cell phones after so many rings if someone doesn't answer in the office? I tried contacting some local companies but they seemed like idiots, if anyone can steer me in the right direction I would appreciate it.
