Missed a call from this number; they accidentally left me a voice message. It's very crackly with several voices in the background. I can't hear much of what was being said but I can hear that the accents aren't Australian, European or American.

When you call back - the message on the number is "this number is not connected".

SPAM - telemarketing

This number cold called me to sell some investment scam. Male with an Indian accent. After I asked a few questions, he asked if I was on the Do Not Call Register, I said yes, and he apologised and hung up !!!!
I rang this number back and was told it was not connected !!!

Picked up call from this number and robotic female voice said "Goodbye" and the line went dead.
