I implemented a system similar to this, where callers would be automatically given an explanation of not wanting to be called. After that they were put on a direct line with Rick Astley’s best hit.
It also customizes the message by looking for the caller number on spam services, and greeting them. At some point, I stopped receiving unwanted calls.

Too useless for actually ignoring your phone.
Instead of blocking the spam calls, it connects a bot that ties up the caller in a pointless conversation for as long as it can. I'm sure this would result in the telemarketers removing you from their lists themselves.
