As we all know it is Optus, but its not always sales.  Its sometimes courtesy calls, support etc.  As telemarketers work out of the same building and use the same lines our CLI is all the same, were bound by legislation.  

I know because I work for optus and my outbound line has this CLI and I'm not involved with the sales side at all.

I just then recieved a call from this number. A lady asked saying that they are offering me any help... and then asked to speak to my mother by saying her full name who is currently the owner of the contract. i got worried didnt answer... she says hello and i hang up. very suspicious. i think i might try calling back the number. see if its a scam. i don't think its actually optus...

Yeah I got the same call from that number tonight....however i left it ring out

But that dog call, I got one from an Indian man a week ago and he said the exact same thing, only difference was I dont know if its from this (08) 8462 6444 number as that one was private

I've had a couple of calls from them since buying my new mobile phone from Optus 2 weeks ago.   Now that I know who it is, I just added them to my contacts as OPTUS.  When phone rings and I see it 's them, I won't pick up.   That's all I can do for now.
