This is the fifth number in a sequence of numbers that phone from Melbourne. My phone automatically silences unknown numbers not in my contacts. If you are not in my contacts, I couldn’t care less if I ever speak to you or not. All of these numbers are being blocked so could the scammer is kindly move onto the next person.

Silent for 5 second then just "Goodbye". Most likely scam, spam, etc.

Rang for 45 seconds @12.45pm on a Saturday. If ur not in my contacts I wont answer & waste my time with scammers n marketers. Driving me nuts that this happens.

Some sort of dialling machine is this caller, checking to see if the target answers. After about 10 seconds of silence an American male recording says "goodbye". I won't be answering 03 9001 numbers any more.

These pests again changed the last digit rings 3 times and stops no message left..
