Who called from 8289743171

I got a phone call  from this number at 9:36 AM today. It rang about four times before I got to my cell, I answered and the caller hung up right after I said "Hello."
I attempted to call back twice at 3:31, and again at 3:40.
The line was completely silent, no ring or anything for about 15 seconds. Then I got a busy signal.
Extremely weird.

i also got a call from this number and i called back..it was silence at first then busy..

same thing happend to my husband
