This call showed as coming from Sydney, NSW. When I answered there was a delay of several seconds, then a short burst of sound which sounded like voices at a call centre, then the call was disconnected from the other end. I suspect it was an attempted scam call.

What sounded like talk to text; Claiming to be from Amazon Prime

Caller: Scammer

Scammer pretend he is from Immigration, speaks Chinese.

I immediately denied the call as it came up as suspected fraud...then immediately got an mms with attached voicemail....IN CHINESE. Needless to say, I was very glad I didn't fall for answering it!!
