I have a Panasonic phone and can block up to 30 numbers - filled that up in no time flat. Sometimes when I block one number, same telemarketer calls again - maybe one digit in the number is different. I occasionally just push speaker phone and walk away. I've registered on that list more than once - it is useless. My sister cancelled her landline and solved the problem. She has never received a telemarketer call on her cell in over a year. I might do the same thing. Too bad one has to resort to that!
