This is about the eighth time my mobile has been bombarded with an unwanted call from an unknown number in about 15 hours. But this was a bit different, as I always call back from a blocked landline and usually get either a pronounced Click and then silence, or a recorded message saying, "The mobile phone you are calling is currently not accepting incoming calls".

This time after I called back, it actually rang once at the other end, then silence. I called again and it rang once, then went to a human message. A real person's voice saying to leave a message. So I left a message saying that I think his number had been hijacked.

Thanks Reverse Aust.
