Ed,
I'm doing that exact scenerio for companies here in Vegas using a Samsung OS7400. However, I could do the same with the OS7100 or OS100 all of which are priced competitively with the STS. (Depending on configuration.) The only question I have is since the DID is associated with multiple extensions when it is forwarded do you still want it to ring the extensions in the office. (What I'm mean is do you want the cell phone to ring in conjunction with the internal extensions?)
