Suspicious Activity Reported for 03 9559 6646
A contributor has flagged 03 9559 6646 (also written as 0395596646) as a suspicious number showing signs of caller ID spoofing. The Telstra-allocated Melbourne landline received a missed call, and when the contributor called back, they reached an automated message claiming to be from Optus advising that the mobile number dialled had been disconnected.
The pattern suggests 03 9559 6646 may be a legitimate landline number being used to route calls through spoofing technology, masking the actual caller's identity. The disconnect message is consistent with scam tactics that use misdirection to confuse recipients about who is actually calling.
What the Callback Revealed
The contributor's experience with 0395596646 shows a classic spoofing indicator: the initial missed call came from what appeared to be a standard Victorian landline, but the callback connected to a recorded message about a disconnected mobile number. This type of mismatch between the incoming number type (landline) and the message content (mobile status) is a hallmark of spoofed or compromised numbers.
Rather than connecting to a person or genuine Optus customer service, the callback to 03 9559 6646 produced only an automated response, suggesting the number itself may not be the actual originating point of the call.
What to Do If You Receive a Call from 03 9559 6646
If 03 9559 6646 calls you:
- Do not: Call the number back immediately, assume the incoming call is legitimate, or respond to any urgent requests for personal information
- Do: Let the call go to voicemail, verify through official channels before taking action, and block the number if calls repeat
- Verification tip: If a call claims to be from Optus, hang up and ring Optus directly using the number on your bill or their official website rather than using any number provided by the caller
Why Caller ID Spoofing Matters
Number spoofing allows callers to display false caller ID information, making it appear that calls originate from legitimate organisations or different phone numbers entirely. The report involving 03 9559 6646 demonstrates how spoofed numbers can create confusion: a Victorian landline connected to a mobile-related automated message is a red flag that the displayed number may not reflect the actual source of the call.
Scammers use spoofing to bypass trust barriers and increase answer rates. A local Melbourne number like 03 9559 6646 appears more legitimate than an unknown or international source, making recipients more likely to answer or call back.
How to Report 03 9559 6646

Missed call. Called back. Says Optus advises the mobile number you have dialled has been disconnected. Guess it’s a landline routing to a mobile that’s not active. Number spoofing.

WRITE A REVIEWFrequently Asked Questions
What does it mean when a callback to 03 9559 6646 produces a different message than expected?
This mismatch is a strong indicator of number spoofing. The number 03 9559 6646 may be a compromised or spoofed landline - when you call back, you reach an unrelated automated message rather than the person or organisation who originally called you. This happens because the actual caller is using spoofing technology to mask their real number, making 0395596646 appear as the source when it's not.
Should I call back a missed call from 03 9559 6646?
The contributor's experience with 03 9559 6646 suggests calling back is not safe. The callback produced only an automated disconnect message rather than connecting to a real person or legitimate service. If you do not recognise the number and it left no voicemail, it is safer to verify any claim through official channels before responding. Do not rely on information obtained from calling back 0395596646.
How can I verify if a call claiming to be from Optus actually came from them?
Never call back a number provided by the caller. If 03 9559 6646 or another number claims to be from Optus, hang up and ring Optus directly using the contact number on your official bill, statement, or their verified website. This ensures you are speaking with genuine Optus staff rather than someone spoofing their identity.
Is 03 9559 6646 definitely a scam number?
Based on the single report received, 03 9559 6646 shows characteristics of spoofing or compromise rather than being a directly managed scam line. The number itself is allocated to Telstra as a legitimate local Melbourne service, but appears to be involved in routing suspicious or spoofed calls. One report is not definitive proof of systematic fraud, which is why verification through official channels is crucial.
What should I do if the same number keeps calling me?
Block 03 9559 6646 (0395596646) in your phone's settings to prevent future calls from reaching you. After blocking, report the repeated calls to the ACMA at acma.gov.au and contribute your experience on Reverseau so other Victorian residents are aware of this number's activity.
Can the real Optus be identified differently from a spoofed call?
Legitimate Optus staff will not ask for sensitive details like passwords, PIN codes, or full banking information during an unsolicited call. If you call Optus back using the verified number on your bill, they can confirm whether they attempted to contact you. The automated message received from 03 9559 6646 did not match genuine customer service responses, reinforcing that the original call was suspicious.
