Whatever happened to plain old "Please leave your name and number after the beep"?

So I was calling some NSman at work the other day, and the call gets connected:

Me: "Hello?"
Him: "Hello?"
M: "Umm, hello, XXX?"
H: "Hello, hello? Who's this?"
M: "Uh, hi, this is J-"
H: "IT DOESN'T MATTER WHAT YO' NAME IS!! *beep*"


...WTF dude!?
