calls, hangs up or no msg. Must be call centre, don't believe it is really Telstra. Spam/Scam

Definitely a call centre of some sort could hear people talking in the background then they hang up phone. Just Block this number people they are a nuisance.

this is the Telstra Business Centre No and I receive numerous calls from them that hang up just as I answer. Most annoying - I have opted out of their calls so this should not be happening, nevertheless it does.

Got 5 calls from this number in a ten minute space. No details or message left. Added to junk caller file

I keep getting calls from this no.
