Who called from 9898919405

Someone called me from 989-891-9405. I answered and a man's voice said "hello" and hung up.

Exact same thing just happenned to me.  Not that I want to talk to some stranger who is probably going to try and sell me something, but why hang up after hello?

Yeah next time they call. I hope they are prepared for a rude awakening.

Just happened to me. Weird.

Got the same call ten minutes ago--dude just said 'hello.' Sounded a little confused. Then nothing.
Anyone else have ATT services?  I wonder if it's related to ATT U-Verse--dealt with that this weekend.
