I got a call from that same number , couldn't pick up because I was at work. I called back but it was busy. They didn't leave any voice mail and it was written "PRIVATE" for the name. This is quite unusual because it usually says "Hidden Number" or "Private Number" on my phone if it can't retrieve the phone number of the caller.

Someone calls from this number and says something but I couldn't hear what they said cause there was too much noise in the room. Than I called it back. It rings a few times than beeps a couple times, and than there is silence as though it's waiting for a message.

I too just received this number - but at 3 a.m!! It's disturbing to get calls at this time in the morning. That person waited for the voicemail but after 1 second of silence cut the phone.
