Strange. Missed a call from this number, when I call back on my mobile I get a message immediately saying "call failed".
Probably a scammer or cold caller.

Caller: tel:(08) 9235 9999

They victimised me

My contract had run out and they wanted to know what I wanted to do next.

This number called us, new my name and played Telstra music and had the exact telstra voice message for feedback ... what can happen we gave them drivers Li number and dob? Only

I called back number (08) 9235 9999 rang 5 times then goes to busy tone.

After talking a while I noticed caller hasn't got much knowledge or interest in Telstra, rather just giving me a load of sweet talk as to what they will do to support etc etc.
Sounded very suspicious. Will report this to Telstra as we all as aurhorities
