I haven't had many telemarketers calling until today. This number called a little while ago. Last night I got a call and picked up, no one was there. I found out from 800 notes that these random no answer phone calls are set up to decide if you are what they call a "live number". I have learned my lesson. Simply put, don't answer the phone, if you don't recognize the number or i.d. of the person calling you. If it is important enough they will leave you a message.
