Same deal.  Keeps calling me and hanging up after a few seconds.  I rang it back and it was a recorded message saying something about products and services but doesn't state what company they are. I'm on phone to telstra now to report it.

I answer it and it lasts a second before it hangs up.When i call back (with the 03 part infront) its something to do with telstra products and services.

constant calls...hangs up when answered.

Bloody anoying calls that are disconnected when answered

Same (03) 9862 6460 hangs up after I answer. very strange.

They just called me then..didnt answer it , its happened before..so annoying!!!!!
