Simple solution to the low bell situation is to fit a BT socket as used on systems . Don't know the type/part no, and don't have one to hand, but it had circuitry inside, which when Driven by a 50v from the system gave extension bells some oomph. Then again, there's the ringer converters as fitted to system phone systems( where there was no provision for an extension bell ) to have an outside bell ring on external calls.
