A repeating nusance/ no voice call. How to block calls like this??

just another annoying number that rings and hangs up just as you answer it and when you ring back just drops out

Website SEO. etcetcetc. Blocked caller as they keep ringing.

possibly Telstra do not call center, it is infiltrated by corruption network, it is in this state, they play mind games, get google should I answer free app for your mobile & feed the nuisance callers numbers in, blocks the call

Sick of these calls

calls 3 to 4 times a week, every time I answer no one on the other end.

Just rang hung up when answered

Another telco no answer 2to3 times a day Arrrrrrrr

They just called me and I asked her out

just call but nothing say anything.

Same as the above comments. Annoying.

rang, but no one answered my hello.

Marketing calls that introduce themselves with 'This call may be recorded for training purposes'...WHAT do these people think???
WHO CARES about their training??

experienced exactly the same. It rang ....no message. I returned call....never even registered, just dropped out.

Do telco's register numbers to anyone? Terrorists?

Do they care?

I agree
