4 Calls in the last 10 minutes to our business 800 number.  First three calls I let our answering service pick up and there was no one on the other end. 4th call I answered and still nothing on the other end.  A real PITA when I am trying to conduct business and they keep calling, would prefer for them to leave a message or at least speak to me when I answer so I can tell them that we are not interested in whatever it is they are selling so the phone calls stop.

We are getting repeated calls and there is no message left or no response when we answer. It is a huge nuisance and disturbs the household.

Colorado Springs. I always let voice mail take over (with caller ID) at my business and this caller inevitably hangs up midway through the recording. Been getting this one for months on end.

received two call in the last 24 hours.  First went to voice mail, no message left.  I answered the second call and it was silence for over a minute before the caller disconnected the call.  Weird.
