I called back the number it was busy. Then I tried again and again. It rang but more dialing. My guess its a prank caller or a random dialer that continues to call different numbers back to back.

I heard when i called back. Sound like a conference call. It was a chick saying how she's pretty and wants to date... Probably, one of those numbers where you call if you want to talk to a female and share your fantasy with. or some online dating crap.

That is a number from the University of California RIverside
