IMHO, you can take cover off any phone and remove the wires from the dialing unit.
from Yahoo:
There is a feature that most large home phone companies have called "Dial Lock" The way it works is: you have to put in a pass code to be able to dial information, since it is a pay per use feature, as well as long distance calls. So, you can still make your long distance calls to friends & family by putting in the pass code, and those who don't have the pass code can not. It does have a monthly cost, but I'm sure it would be cheaper then paying for high long distance calls, that someone else is making on your phone. Call your local phone company to see if they have this feature, that sounds like just what you need.
