Didn't even hear the ring.  Looked up the number with no results.  Called back the number within the hour and got "this number has been disconnected or is no longer in service" message.  Scammer darkly.

Received a call from 407-200-4000.  It's an obvious scam: auto-dialer robo-call.  Caller ID said "Florida Hospital".  I answered with my company name and "how may I help you?" and got only dead air.  I stayed on the line but didn't say anything further.  They tried to hang up twice but couldn't as long as I kept the line open.  I managed to tie them up for almost a 90 seconds in order to waste their time like they do ours.

They called my place of business and there was just dead air and then a hang up.  I tried to call back and there was no ringing, just that dead air again.
