... scammers are posing as debt collectors seeking repayment on loans
> purportedly taken out by individuals or employees at places such as hospitals. >

> phone lines, and then they flood the lines with repeated calls sent automatically
> over the internet, knocking ... agencies' phones offline for legitimate callers.
