Unknown caller left VM saying my name & then hung up

This caller is a spammer showing up from Nelson Bay NSW, mass calling to several of my work mobiles all with trailing numbers. this was a scam caller due to the region calling no calls were answered and of course they don’t leave VM

Went to voice mail - no one spoke but you could hear heaps of different voices in the back ground

Must be scammers did the same thing called them hung up. I called back and some one else answered the phone then hung up.
