I didn't answer the call, but after about 10 seconds a recorded voice said "goodbye' and the call terminated.

Beware of the following numbers - constantly ringing but don't leave message on the answering machine. Can only assume TOTAL NUISANCE/SCAM CALLERS.
(07) 5369 8501/(07) 4236 9852/034685124/012525113489/(02) 6547 8954.

got the call within 10 minutes of creating an uber account, no message left

Call centre , when I didn't answer , they hung up!!!!!!!!!!!!!!!!!!!

I have just received a call from this number. I picked up, but didn't say anything. Silence from the other end, then hung up. I have blocked the number.

BEWARE! Called on my mobile, said it was about Australian government solar scheme. I said we renting and hung up. Immediately received another call for "Private" number - same male caller saying he had more to tell me!!! OBVIOUSLY A SCAMMER - DO NOT ANSWER. I've reported number.

Scam call just checking if its a valid number
Identity theft - BEWARE

got a call from 012525113489. It's an automatic dialler looking to see if your number answers and then if there is a human voice. If you answer it will add you to a list for more calls. Do not under any circumstances give them any personal details. Don't say anything if you can avoid it. Just hang up, then call your local, state or federal politician and tell them to fix it. These and other criminals have destroyed our telephone system.

I think this is a Telemarketing Bot. Answer the call, no-one on the other end and about ten seconds later automated voice says "Goodbye". Five to ten minutes after that, without fail, a Telemarketer will call you.

I did answer this: kept saying ‘hello’ to no response: then got a recorded message just telling me ‘goodbye’. Creepy. When I called it back, the message said Optus has disconnected this number. Very creepy.

answered this call, no one spoke so I hung up

The number was on my missed caller ID when I got home, but I didn't bother rtnging back back

Didn't answer let go to answering machine no message left.
