What is this number? It's invalid...

Called my number also I'm in tassie and I tried to call back and the number doesn't dial or comes up busy!

I'm in Tassie as well & on Telstra. Got the same thing. Missed the call while at work & when tried to call back later the call ends straight after dialling. I am not dealing with any real estates or buying/selling  for Peter Lees real estate to be ringing me

Hello,I just recieved a call from this number. What was you calling me for??

Yep, mine was to a mobile too, no message left and number invalid when I tried to return the call.

I have had three calls in the last 2 days.. When at work my phone is on silent so I cannot answer the phone during this time .. I have phoned back and get a busy tone or a message to say incorrect number or not connected... How can this be... (03) 6331 8123. !!

I'm in Tassie also (and with Telstra too) and I got a missed call from this number this morning on my mobile. Thought it was a bit odd that when I rang back I just get the busy signal. Wierd!!
