I pick them up on purpose, bate them, waste their time, call them back, waste more time. It can be fun sometimes, had one hanging on me the other day, I was laughing so hard. "Stop calling us!", "Stop calling you?! Bro stop calling and scamming people!" lol... Im also always looking out for AI phone systems as well. It's real fun messing with those, specially when you can get them off the rails.
