Silent Call Report for 04 6809 0652
One contributor has reported receiving a silent call from 04 6809 0652 (also written as 0468090652). The call featured a brief moment of two-way audio before the caller disconnected, which is characteristic of callback verification scams or automated systems testing active numbers.
The contributor answered the call from 0468090652 and heard a message asking 'can you hear me'. When the recipient responded, the person on the line indicated they couldn't hear the response and then hung up. This pattern raises concerns about whether the number is being used to confirm that the phone is actively monitored by its owner.
What Happened During the Call from 04 6809 0652
The call to 0468090652 began with a pre-recorded or automated message asking the recipient to confirm their presence. Despite the recipient answering and responding, the caller claimed they couldn't hear the response and immediately ended the call. This type of interaction is often used in callback scams, where attackers verify that a number is active before attempting a follow-up call with a more sophisticated social engineering attack.
The brevity of the interaction with 04 6809 0652 suggests this may be part of a larger calling campaign designed to filter active numbers from inactive ones.

WRITE A REVIEWFrequently Asked Questions
What is a silent call and why would someone call 04 6809 0652 to me asking 'can you hear me'?
A silent call where the caller asks if you can hear them is often a callback scam verification technique. Scammers use these calls to confirm that your number is active and monitored by a real person. Once confirmed, they may call back later with a more elaborate scam (such as impersonating a bank or government agency). The report of 04 6809 0652 shows this exact pattern: a brief audio check followed by immediate disconnection. Avoid engaging with such calls.
Should I call back 04 6809 0652 if they don't leave a voicemail?
No, do not call back 0468090652 under any circumstances. Calling back a number that called you with a silent call or unclear purpose can confirm your number to scammers and may incur charges. The contributor who received a call from 04 6809 0652 experienced the caller hanging up without explanation-this is a sign to block the number and move on, not to investigate further.
Is 04 6809 0652 definitely a scam or could it be a legitimate company?
Based on the single report, 0468090652 exhibited behaviour consistent with callback verification scams rather than legitimate business practice. Legitimate companies typically leave clear voicemails, identify themselves, or don't disconnect when you answer. The 'can you hear me' pattern from 04 6809 0652 is a known scam tactic. However, one report is limited data. If you receive additional calls from this number, keep records and report them.
How can I block 04 6809 0652 on my Optus mobile?
Most modern smartphones allow you to block numbers directly. On your Optus mobile, find 04 6809 0652 (or 0468090652) in your call history, select it, and choose 'Block' or 'Block Number'. On Android, you may also use the Messages app to block spam. Optus itself may offer additional filtering through your account settings at optus.com.au. Blocking is the fastest way to prevent further calls from 04 6809 0652.
What should I do if I receive similar 'can you hear me' calls from other numbers?
Silent calls or 'can you hear me' calls from any number should be treated with caution, similar to the report from 04 6809 0652. Do not engage, do not confirm your identity, and do not call back. Block the number immediately and report it to ACMA at acma.gov.au. These calls are often part of callback scam campaigns testing large number lists. Report each instance to build a pattern.
Could 04 6809 0652 be a robocall or automated system?
Yes, it's likely that 0468090652 was an automated or semi-automated system rather than a real person. The initial 'can you hear me' message and the claim that the caller couldn't hear the response despite technical capability suggests automation. Robocalls and auto-diallers are commonly used in callback scams to filter large contact lists. The fact that the line went silent when the contributor answered indicates the system may not have been sophisticated enough to handle responses.
