The same thing has been happening to me, another number they are using is..88970813 which is out of service when I call it back, as well as 88200175 and as of today 90371309

I've been receiving 2-3 calls a day for the last two weeks from (02) 8820 0715 RP Australia. As soon as I answer they hang up. Would love to know how they got my mobile number

I keep getting calls from this numb (02) 8820 0715 answered an they said is this sam and then hung up call back they say experiencing high volume of calls

i just recieved a call from (03) 8506 0477 and they hung up as soon as i answered. then when i called them back it was again a message bank saying welcome to RP Australia. after googling RP Australia i found a website that says contact your local police station and report the number because it may be a scam

My call was from (03) 8506 0477. All the rest was identical. Background hum and a swift Hang Up on my answering. Called back and got the message "RP Australia is experiencing a high volume of calls"
WTF?

Missed call on my mobile from (02) 4602 6003. When I phoned back I got a recorded message: "Thank you for calling IP Australia. We are experiencing a high volume of calls at the moment ... leave a message ... first and last name with your number, so we can attend to your enquiry."

When I google "IP Australia", it is the Government department for Intellectual Property, Patents, Copyrights, etc. It is in Canberra with numbers starting with 0262.... and does NOT show this contact number.

Australian phone numbers beginning with 0246... are in the Campbelltown NSW area.

So yes, seems VERY dodgy!!!.

I just missed a call from this number. Called it back and got a recorded message saying "Thank you for calling RP Australia. We are experiencing a large volume of calls. Please leave your name and number and we will call you back". No idea who they are or what they do!

(02) 4602 6003 when I ring back after a missed call I get RP Australia is experiencing a high volume in calls

Answered call, was hung up on after hearing background noise. I never call people or businesses back, usually these type of calls are a waste of time calling back. I am on the do not call register.

Missed call. Unknown caller. Similar pattern (time of day, quick termination of dialing) to recent calls from (02) 8705 3274, (02) 8404 0627, (02) 9346 4500.
[Repeat after me: - "I'm sorry I don't take charity, promotional or survey calls. Thank You. Goodbye!" CLUNK] (The three types of calls still permitted even if you're on the "Do Not Call" register)

I got the same - Missed the call then when rang back it said number was not in service

i missed a call from this number. When I rang it there was a recorded message that said the number was not in service. How can that be?
