Picked up phone and there was silence on the other end.

I called back and I can't remember the full the full name of the company but it was something Health & Dental.  The woman who answered said the call was in regards to my inquiry into health insurance coverage.

Received call from this number, when answering machine picks up.  The woman caller just says my name twice and then hangs up.  I plan on blocking this number.

Added to block list calls and never leaves message. It is annoying because I can not always answer while working.
