I received three calls to my cell phone from this number (back-to-back), at 4:30am. It only rang once the first two calls, then repeatedly on the third. I did not answer any of them. Not sure if I learned this from this site, but somebody on a call reporting site had one possible explanation. As you can see, the number contains "too many" numbers. The explanation was that the call was a function attached to the way the cell service transfers the notice that you received a voice-mail. I did have a few voice mails in close proximity to the calls. ???
