I got a missed call from (02) 9112 5000. I didnt answer. When I listened to my voicemail, some girl kept saying "Hello" few times and hung up.

Every day around the same time my partner gets a phone call from these people. As she doesn't recognise the number, she never answers it, but it's really becoming a problem. When she called the number she got a recorded message claiming to be the Hosted Contact Service and that they would be calling her soon. Ominous.

I also get a phone call (Adelaide, Australia) twice a day from this number. When I answer no one is at the other end of the line. The phone just hangs up. Needless to say I really want to speak with whoever it is so I can get some details and them annoy the cr*p out of them.
