caller id says Health Info --  they left no msg  on ans. machine - we also r on do not call list - a lot still get thru - annoying.

Caller ID lists "Health Info" - automated message is regarding lowering mortgage payments. Wanting more info requires leaving your telephone number for a call back at a designated time you provide. I did not get the call back at the requested time

The caller from this number to me was looking for 2 people who they were trying to collect a debt from.  Same guy and same woman calling me. I told them for over a year that this number was now my  number and asked them to note it in their files.  The last time I talked to the guy he got really snotty to me so I have blocked their number.

I just got a call from these people, ID says Health Info. Reading through these posts it has become obvious to me that these folks are an illegal operation that can "outrun" the government, and since we have a totally incompetent clown in the White House it seems easy to outrun the government. We may have to inundate the government with endless calls to get them off their butts and enforce the law.

probably just an autodialer/robodialer/war dialer (all illegal under federal law) and if nothing else they can list if your phone was ringing (an active number), answered, or disconnected. That list could be then used for more 'sales calls'. I wish there was some magic hacker trick that would plug their call into 22 vac from MY end, but only affecting THEIR end.
In fact, from what I have read of black letter law, this also constitutes criminal conduct, i.e. creating/maintaining a public nuisance.
I wish I had the time to petition a Federal court for a writ of mandate - a court order forcing the appropriate agency to DO THEIR DESIGNATED JOB! They do exist, and that is what they are for.
