02 7820 3924 (0278203924): 2 contributors report missed calls with no voicemail left. Sydney local number raising questions about caller intent.
Silent Call Reports for 02 7820 3924
Two contributors have reported receiving calls from 02 7820 3924 (also written as 0278203924) that left no voicemail message. Both reports describe a Sydney local number that rang through but disconnected without attempting to leave any communication, which is unusual behaviour for legitimate callers.
The pattern of calling without leaving a message can indicate several scenarios: robocall testing, callback scams where the intent is to trigger a return call, or automated systems verifying active numbers for later targeting. Contributors who received calls from 0278203924 found the silence and lack of message particularly suspicious because standard business or service calls typically include voicemail details.
Call Patterns and Contributor Reports
Both reports of 02 7820 3924 came within hours of each other, suggesting either a focused calling campaign or coincidental timing. The first contributor reported a missed call at 06:11 UTC with no message left. A second report arrived at 01:44 UTC the same day describing identical behaviour - a phone rang but no voicemail was created.
Contributors did not answer either call from 0278203924, allowing them to go to voicemail where silence or no message would typically be recorded. This defensive response is appropriate when receiving unexpected calls from unknown numbers, particularly Sydney local numbers that provide no identification or purpose.
What to Do If You Receive a Call from 02 7820 3924
If 02 7820 3924 calls you:
- Do not: Answer calls from unknown numbers, return the call to 0278203924, or feel obligated to respond to missed calls without voicemail
- Do: Let the call go to voicemail, check if a message was left, block the number if calls repeat, and verify any claimed identity through official channels using publicly listed numbers
- Consider: If this is a callback scam attempt, returning the call could connect you to premium-rate services or scam operators. Silent calls followed by repeat attempts are a known callback scam indicator
Report Patterns and Allocation Details
02 7820 3924 is registered as a local NSW service through Symbio Networks Pty Ltd. The allocation to a legitimate service provider doesn't guarantee legitimate use, as phone numbers can be spoofed or compromised. The fact that this Sydney number has generated two separate reports within a short timeframe suggests contributors are actively reporting suspicious activity rather than isolated incidents.

WRITE A REVIEWFrequently Asked Questions
Why would someone call from 02 7820 3924 and leave no message?
Silent calls with no voicemail are often callback scam tests where callers are trying to confirm active phone numbers for later targeting. Occasionally they're robocalls checking if a line is monitored. Two contributors reported calls from 0278203924 with no message, which fits this pattern. Legitimate businesses almost always leave voicemail details explaining who called and why.
Should I call back 02 7820 3924?
No. Do not return calls to 0278203924. If the caller was legitimate, they would have left a voicemail message. Returning the call could connect you to premium-rate services, scam operators, or confirm your number is active to persistent callers. If it's a genuine service provider, they'll contact you again and leave a message.
Is 02 7820 3924 definitely a scam?
Not definitively. The two reports from contributors describe suspicious behaviour (silent calls with no message) rather than confirmed scam tactics. The Sydney local number is registered to Symbio Networks Pty Ltd, a legitimate provider, but that doesn't mean the number is being used legitimately. The pattern of leaving no message combined with multiple reports suggests caution is warranted. Block the number if it calls again.
What if I answered a call from 0278203924 and the line was silent?
Hang up immediately. Remaining on a silent line can trigger automated systems to transfer you to a scammer, activate premium-rate charges, or confirm your number is actively monitored. Contributors who let calls from 02 7820 3924 go to voicemail were protected by not engaging. If you answered and heard silence, do not call back and block the number.
How do I block 02 7820 3924 on my phone?
Most Australian phones allow you to block numbers directly. On iPhone, open your call log, find 0278203924, tap the info icon, and select Block This Caller. On Android, open Phone app, find the recent call from 02 7820 3924, press and hold, then select Block Number. You can also contact your service provider to request network-level blocking for this number.
Should I report 02 7820 3924 to ACMA?
Yes, if you receive unwanted calls from 0278203924. ACMA investigates patterns of nuisance calling and can take action against persistent offenders. Report at acma.gov.au. The more reports they receive about 02 7820 3924, the stronger the case for investigation. Community contributions here on Reverseau also help identify broader patterns affecting Australians.
