I'm at the front desk of a hotel. Line the caller called was 1-800-622-3022. No reply to my greeting. Most nights are quiet, but I sometimes will get 4-5 calls on that line with a city/state instead of a name showing on the caller ID and no reply to my greeting. I suspect a robocaller checking for valid numbers for telemarketers.
