This caller has called our VoIP (directory listed) number five times over three days (must be a retard) as I have switched our router answering machine to answer in five (5) seconds but they still keep calling.
No message is ever left but from the other comment they are telemarketers or scammers! Seems they will never give up, our answering machine has a generic message.

This number calls the same time every day and doesn't leave a message. Very annoying.

Repeatedly calls and I always ask them to not call again and as soon as i say that, they hangup

Called today, answering machine picked up the call instantly hanged up. Spam caller

Called back and an 'operator' told me that the number was disconnected

I called back number (02) 8866 2721 it says the number I have dialed is not in service anymore.

Spam Caller trying to cold sell

Auto caller, many calls, hangs up on answer machine.
Bored: Decided to answer call:
Female American accent -
Wanted to send free product(s) from an extensive range.
Unfortunately range didn't include sex aids.
Bummer (so to speak). :-)
