Annoyed by telemarketers? Too polite to abuse them or just hang up? Can’t be bothered wasting their time in person? Then you need AstyCrapper. If you’re using the open-source Asterisk PBX, it will crap on for ages on your behalf. It works by detecting responses from the telemarketer and silence gaps and responding with a series of recorded samples. It’s pretty convincing!
OK, maybe that doesn’t apply to you, but you can still have a good laugh at the example calls.
