Just got a call from this number, displayed as Healthstream. I didn't pick up. I wish the DNC registry actually worked!!! It's so frustrating. I actually got a call in the middle of the night or Sunday morning after a long night of working and it woke me up. The person on the other end really got an earful. I know its their job but damn!
I've been getting calls from this number the last couple of days, and interestingly, I was in the hospital just about a week prior (as others have mentioned the connection). And thanks for the information above, 'phone man'.
