I suspect it to be a scam caller... I missed the call but I got a notification that there's a message left on my voicemail. The voicemail message is simply a 2-minute silence. I suspect the caller just wanted to "fish out" information -- part of which is my name as mentioned in the greetings recorded in the voicemail.

I called back the number (07) 3077 8915 and reached vm but couldn't hear the company name
