Just got a call from this number and they hung up when my answering machine started.

This is a business phone both numbers. I use are signed no call list.

Business phones are not covered under the DNC.  Private phones only.

458-201-1660 called our office.  Left no message, hung up.

458-201-1660 just called our business, again. Caller ID shows GIGMEMBERSHIP. It's an illegal robodialer with a pre-recorded message. Female voice spiel went as follows - "Hi, this is Kelly, and after careful review your business qualifies for an eight thousand dollar platinum small business credit card. Blah blah blah. Press 1 now to speak to a representative. Press 1 now. Press 1 now to take advantage of this special offer. Press 1 now. Press 1 NOW!" Call offers NO Opt-Out option, which is required by federal law. Will be reporting the call directly to the FCC.gov website as harassment, as the calls from this number are coming in at all hours of the day and night.
