Hey, I wanted to let you know that if you can't find this telezappher, or even if you can, you may want to add your name and phone number to the national do not call list. I did so about 2 years ago and I have hardly any telemarketing phone calls. It is really nice - if they do call you, you can file a complaint. I maybe have one every three months or so come in. Best part is this is completely free!
