There’s an even better way to handle spam calls if you have a recent Android phone: use the automated call screening. Every time robocallers hang up immediately before saying a single word because they know if the person flags the call as spam then Google now has a recording to automatically flag future calls even if they spoof new phone numbers.
The call screening is done on-device, but if you flag a screened call as spam then you get the option to send the recording to Google. I’m guessing those get fingerprinted and then used to detect spam when screening other calls.

iOS user here: Is Android fingerprinting voice samples for this‽
