I answered and heard "hello, hello" and then a hang up.

Jerks just stayed quiet as I said hello, then hit a number button and held it for a sec. I said hello again then cussed the idiots out.

Had same problems as listed above.  I also have caller ID and would not pick up future calls.

Just tried calling here; I let it go to the machine.  Dead air - so I picked up the phone and hit numbers for a few seconds then hung up.  No clue who they are or what they want.

had a call fm this #, i let it go to voicemail and they stayed on for about 15 seconds, then hung up they didn't say a word.
