Hehe nice one.
I once got called by a number I didn't recognize. I did notice that it was a foreign number. As soon as I answered, it got hung up.
I decided to google the number. I found out it's used as a scam. They were hoping I would call them back. If I had, they would have gotten a lot of money from me.
And a friend once got a few text messages from Turkey. Somebody also had the wrong number.
Jason, I'm exactly the other way around. I hate listening to my voicemail. I reckon that if it's important, they will call again or send me a message.
Of course in the end I still listen to them...
