Robo call at work. Left a message, but it was cut off. Something medical, but message was cut off. Probably the medical monitoring system that was already reported.
I work at a university switchboard. They have called nearly every extension in our system. One of those "this is not a sales call" FBI alerts about putting a sign in your yard. So very annoying!
I know this is a robo caller because they come in directly to our unlisted office helpdesk backlines which are in consecutive order XXX-XXX-2900, 2901, 2902, 2903. Meaning, if I hang up on this call I will immediately get 3 more calls in order that I must hang up. No one knows these numbers exist except for a few of us in IT because they are only for calls forwarded from our main line. Clearly this is some shady company with some selfish [***] owner that thinks this type of "marketing" actually works. Bunch of low life pond scum, like email spammers and malware writers.
