For the past three days I've received a silent voicemail without the phone ringing.
The first time it happened I thought I just hadn't heard the phone but it happened this afternoon while I was sitting next to the phone on the charger.
It is a slightly different number each time. They all begin 0333 053 27XX. Then XX are two random numbers.
It's obviously spam but how does it get to my voicemail without the phone ringing (no diverts set-up on the phone)?
