Fortunately, my outgoing message is just rude enough to alert the caller's attention...It begins with a brief but unmistakable flatulence, then proceeds to warn off any 'sales pitch, religious or political hack, scummers and poll takers because we just aren't interested'. They usually make it just past the 'toot', and I get these 5-10 times a day...the scum scammers, not the frijole explosions.
I got a call with a female recorded message stating that someone had requested information about a back brace. I blocked the number but I am almost sure I will get the same call with a different number next week as this has been going on for years.
