Very strange. I missed 4 calls from (02) 3846 2117 while I was working. I only just issed the last call, but when I called back the msg I got was; Optis advises the number you have called is no longer connected.

An delay after anwering, so I hung up as generally these are spam computer calls. On dialing the number with my number hidden, I get "this number is disconnected ..." so this does not look like an honest number.

i called back number (02) 3846 2117 rang 3 times then goes to busy tone.
