Caller: Autodialler

missed call from this number which says is from Kalkallo, VIC
Called back and just an automated voice claiming to discuss elec & gas offers.

Two calls in one day; each time no message left. See others' comments. Likely telemarketing

(03) 8103 7094 - call disconnects around 5 second after being answered.
Most likely a robocall or telemarketer auto-dial machine checking which phone numbers are in use to allow staff to scam call these numbers at a later stage.
