Caller ID : Montpelier VT
Unknown caller; let it go to the answering machine. No one spoke, but I could hear murmuring in the background (sounds like a call center to me!). Then they hung up.

I've received 3 calls from this number in the last 3 hours, I do not answer, put the number on auto reject. They do let it go to voicemail, all I hear is a humming. I've been on the do not call list since 2012 but I've been getting all sorts of phone calls in the last 3 days from random numbers. So annoying. I'm about tempted to change my number.

I did not answer, went to message. Layer message,  in background you can hear it's a call center...man then said hello twice and hung up. I live on West coast this came from Vermont.
