This time I answered it. It was from the Chronicle Newspaper confirming my delivery of the paper.

I don't answer when a call from this number comes through.  I feel that if it's regarding legimate business, they should have the couresy to leave a message and then you can decide if you want to call back. Otherwise I consider them garbage and a waste of my time and I don't call them back.

unwanted calls repeatedly

Did not answer.  Caller ID showed VERIFICATION then their number.  No idea who was calling.  Let machine pick up and got recorded message stating "Hello, this is a service verification.  We will call you back later.  Thank You."  

Call all you want, I will not answer. Legitimate business's should leave a message.

Received a call / voice mail from 801-839-7365.  The message said it was "for service verification" and that they "will call back later."
