Caller: Telstra again so they say

And not a clear voice on the other end

Didn't answer, seems like a scam

Yet another call no voice

Unknown caller, no message left, equals no return call.
Don’t know, don’t want to know don’t care..

Quite likely fraudulent. Someone or a 'something' called and when I answered they hung up. I suspect they hang up so that you will call them back and be charged a premium price for doing so. A....ho..es!

Called the number back and got a recorded message saying they were 'Aussie health fund" or similar

Caller was identified by service provider as 'potential' fraud, did not take call but curious if anyone has information about this number. In the habit of not responding to unknown numbers.

Need to know who is trying to call us.
