Unknown caller at 2:46 pm on Friday. Called 1:08 min before another unknown caller 0486 872 617 and a 3rd unknown caller 0447 227 610 1:25 min after the last one. They were my only calls for that day. None left messages...is Friday afternoon telemarketer time? Will look for repeat patterns over a period of time. They could be spoofed numbers from the same caller perhaps, or they might be genuine callers who don't like leaving messages. If you don't leave a message I assume you are a telemarketer... that's the way of today.
