I keep getting calls from different area codes. they all do the same thing. you answer the phone say hello and they never reply to you. after a minute they just hang upi

This just happened to me 5 minutes ago. Some man with a thick English accent asked to speak to me and when I said " this is he"  He hung up. What is the purpose of this?

Unknown number came in as missed call. I don't answer calls the number I don't recognize. After received 1st call, if unknown I block it from calling my number anymore.

Keep getting calls from this number...

We have had 3 calls from this number today. I'm so fed up I changed the greeting on our phone. Now these idiots get to listen to me screaming and laughing. (I started to record a new greeting and got so messed up I screamed and then was cracking up...we have been trying to think of a greeting that might shake these idiots up when they call...Tee hee hee  :)

Maybe I'll just do like my grandma used to...get a whistle...answer the phone and blow it really loud...treat 'em just like an obscene caller.
