Received 2 calls in a row from this number, when I answer, all I heard was a beep every few seconds. Called back, and it rang a couple times, and then I heard what sounded like a dial up modem through the phone. A google search says it's a gastroenterologist in New Haven CT. I've never been to them before, or any gastroenterologist at all, so not sure if the numbers being spoofed, or what.
