I had a missed call from this number.
I tried calling it back using the block-callerID prefix 1831 (and then the phone number) and it said number is disconnected, despite it having called me less than an hour ago.
I also tried calling it back without using the 1831 block callerid and same thing, claims number is disconnected.
I'm therefore regarding it as SCAM.

I called back number (03) 8804 5896 rang once then gets disconnected automatically.

Caller: didn't answer

When I called back it says that the number is disconnected

Missed the call and call back, and a prompt comes back saying that this number not in service

Caller: Unknown

I was called by number (03) 8804 5896, when I answered there was only silence.

Caller didn't leave a message. Suspect this is a Scam/Spam call based on others comments about this number blocked to be safe.

Called and no one spoke. Maybe muppets gathering your voice for AI scam purposes?

Called did not leave a message didn’t call back

I get tired of these spam calls. Sort it out Vodafone!

Caller: Claims to be Telstra

when I called back I got a scam alert.
