I think that we should be made aware of this number's origin.

I believe this caller to be either a scam OR a phishing number.

I got only 3 calls today from number +161456987123

keeps calling me at all hours but hide their own ID behind
a virtual business phone number. Got to be a SCAM.

I translated the number to AUS 0456 987 123 = no such number
Looked up code for +161 = no such country code
Looked up 161 found are codes in UK & USA

I am Blocking all calls from this number.

Missed the call, but whoever it was they left no message.

Called the number back and got a message saying the number is not connected.
