1. Get your phone number in another city that you don't live in. Make sure the area code is the most common for that city. Now all the calls you get on your phone from that area code are spammers so ignore them.

2. Callers you don't recognize can leave a message if they want to talk to you.

3. If you do end up in a call with a spammer, then work your way into the conversation to get a real business name out of them. While you are on the phone, you can press them to help you find their business on the web. You may even find a BBB rating on them and inform the caller that the BBB rating is pretty bad. Or you can ask them for a callback number (which they probably won't give) and you will call them back to continue the call. All of these questions should prevent them from calling you again and if you are lucky you have a business name you can further report on the web as a spamming company.
