Got the call. Let it ring.
An automated message claimed that it was Liberty Power telling us to switch and whatever. Annoying.

Caller ID showed as UNAVAILABLE.

This was made to a business line. Ridiculous. I think the FCC should be more strict on telemarketers calling people; especially on business lines. Also, the National Do Not Call list thing doesn't work. I've put in my numbers on that list and then did it again after months (during which I got calls still).

Quite needlessly annoying. I hope Liberty Power goes out of business or the owner of this company goes to jail for harassing people with spam calls!

Answered and heard a phone ring then a person came on who said they were calling from Liberty Power.  That's all I needed to hear and hung up.  Solicitors are getting new phone numbers.  This is the third new number in 24 hours where I'm the first posting.  Caller ID showed Toll Free.
