I got the same thing (FOP) and hung up as soon as he said he would be recording for training purposes. I will never donate over the phone. Sounded just like you described.
This number ( 408-940-3894), has called my home multiple times in the past three months, claiming that he is collecting donations for California's fallen or disabled Police or Fire Fighters. It is always the same man who calls. Do not give out any personal information to him!!! He is claiming that he wants to mail out a kit of some sort in exchange for donations. He has a very authoritary voice with a slight Texas like accent. According to the TV News Stations: The police Depts. and Fire Depts. NEVER solicit For donations of any kind via the phone or internet and again it is always the same man that calls every time. He even called right after a Police Officer of Escondido, California was murdered by her Husband. Please Beware!!!
This number (408-940-3894) called at 12:08 PST and we decided not to answer. No message left......so I called back. Rather surprised to hear a guy with a deep voice say "Hello", but I hung-up to check this site for more info. Sounds like the same old scam....
