I have gotten a number of calls from this number. Twice they let it get to voice messaging and left a 2 second empty message (annoying). The other time they hung up before they left a message. They started calling after I entered my information to query about health insurance for my son, so I suspect it may be a health insurance related call but they won't leave a message and I don't answer calls from numbers not in my contacts list.
My caller ID reported it as possible fraud. I answered but never said a word. They didn't speak for quite a while, then a guy said hello. I still said nothing and they stopped talking but did not hang up. I heard lots of people in the background because he forgot to put it back on mute. sounded like a possible call center but not a professional one. (blocked)
