In the past two days alone, I've gotten over 20 spam calls with none of them leaving a message. Just 3/4 seconds of silence on my voice mail. One call the other day left a 22 second blank message.
I work for a mental health research study and often have to warm call people who expressed interest to book them in for a screening with us.
Finally encountered a Google AI response the other week and got scared and confused so I just hung up and sent an email 🥲
