Who is this? What is a "suspicious" call?

AUTOMATED TELEMARKETING.  UNWANTED CALL. THE NAME OF THE COMPANY IS NOT SHOWING UP ON MY CALLER ID, OTHER THAN " OUT OF THE AREA".

I'm on the no call list.

Company left message talking about free water quality test in my area.

Just got a call a little while ago here in Mass. Offering a free water quality test if you press one. Caller ID just said Valdosta GA. I am on the do-not-call list. Will be filing a complaint with the FCC.

They hit on both points. I'm on the do-not-call list AND it was an automated computerized call.
