It would be nice. You could work around the no call from a desired but unknown number issue by whitelisting approved pay phones (which you'd have to bring back) where someone needs to traipse down to one in person to make a call. Probably would also have to require whitelisting from professionals like doctors, lawyers, etc. But then politicians would want to also be whitelisted too.. so maybe nothing would change other than the fact you'd get fewer calls from overseas to tell you that Microsoft needs you to update your car warranty or you'll be arrested.
