Who called from 9705685208

Got a call from 970-568-5208.  It has called daily for several days and there's never anyone there.

When the answering machine picked up they hung up.

Keep calling and hanging up

Hang up when VM picks ups. Reporting to Do Not Call.

Seems that if they hang up just as folks answer or their machine does it would be easy to feel
they are not accomplishing much of a survey except maybe a survey too verify if their contacted phone numbers are real and active. More should reply here if they actually spoke to anyone and survey details.
Curious if they hang up on some but not others.
