received this no. on my caller ID. did not leave a mess.

Received this number have no idea who it is, but I wish they would stop calling.

I received a call from this number and it was labeled INSURANCE.  When I try to call this number I am told it is an invalid number.  That sounds suspicious to me.

I check my policies and this number does not appear on any of them.

Did not answer.  A recording was left ending with "...or other medical problems.  Whole life premiums never increase and benefits never decrease.  You also receive a discount prescription card with each policy.  If you'd like more information at no cost or obligation, please press the 1 key on your phone.  Not interested?  That's okay.  Press 2 to be added to our no call list."

Life insurance.  Called a number that is on both US and TN DNC lists.
