Silent Call Report for 04 0198 4343
One contributor has reported receiving a call from 04 0198 4343 (also written as 0401984343) that exhibited classic silent call behaviour. When the contributor answered, they were met with complete silence and no voicemail was subsequently left on their device.
The call came from an Optus mobile number. Silent calls like this one from 0401984343 can be part of several different patterns: some are callbacks from scam operations testing whether a number is active, others are robocall systems probing for live contacts to add to spam lists, and occasionally they result from disconnected outbound dialling systems.
What This Type of Call Means
A silent call from 04 0198 4343 where the caller disconnects without speaking or leaving a message is a known indicator of several activities. The lack of any voicemail message suggests the caller was testing the line rather than attempting genuine contact. This behaviour is frequently observed when scammers or automated systems are verifying that a phone number is active and monitored by a real person.
The fact that the call connected and was answered, combined with the immediate silence from 0401984343, fits a pattern where systems are collecting data about which numbers are live contacts. Contributors who experience silent calls like this one from 04 0198 4343 sometimes report follow-up contact attempts within days, often from different numbers.

Silent Call Callback Scams

WRITE A REVIEWFrequently Asked Questions
What does a silent call from 04 0198 4343 mean?
A silent call where you answer but hear only dead air, like the one reported from 0401984343, typically indicates the caller is testing whether your number is active and monitored. This is common with scam operations or automated dialling systems checking which numbers to target with future attempts.
Should I call back 04 0198 4343 if I missed the call?
No. Never call back 0401984343 or similar numbers that called you silently. Returning the call confirms to the operator that your number is a live, monitored contact, which makes you a more attractive target for future scam attempts. The Optus mobile number may connect you to a premium-rate service or data harvesting operation.
Is 04 0198 4343 a known scam number?
One community report indicates 0401984343 exhibited silent call behaviour, which is associated with callback testing and scam verification systems. However, a single silent call doesn't definitively prove scam intent - it could also be a disconnection or system error. If you receive repeated calls from 04 0198 4343, the pattern becomes more suspicious and should be reported.
How can I block calls from 04 0198 4343?
On most Australian phones, you can block 0401984343 by: opening the call history, selecting the number 04 0198 4343, and choosing 'Block' or 'Add to blocked list'. Some phones also allow you to register with the Do Not Call Register at donotcall.gov.au, though this may not stop all scam calls to your number.
What should I do if I receive multiple calls from 04 0198 4343?
If 0401984343 calls you repeatedly, especially with silence: block the number immediately, report it to ACMA at acma.gov.au, and consider reporting to Scamwatch at scamwatch.gov.au. Multiple calls from 04 0198 4343 following an initial silent call can indicate the number is part of an active scam campaign testing your responsiveness.
