I got a call from this number too, I hung up after not hearing anyone after 3 seconds. First call at 1:12 second call at 4:28

0485 814 175 called me twice a few hours apart. I answered but hung up after a few seconds. I didn't hear anyone talk.

This number rang around 6.30pm on a Monday Sydney time and i missed call. I rang it back at 8.pm and it did only one ring, followed by silence, then a male voice (it sounded real) said "Hi.. is this (my first name) ?" And I called with my number on Private so I don't know how they identified that it was from my number and knew my first name.
