WRITE A REVIEWFrequently Asked Questions
What does it mean if 02 9129 8812 calls and hangs up immediately?
A silent call followed by disconnection is typically an automated system confirming your number is active. The contributor who reported 02 9129 8812 experienced this exact behaviour. These calls are used to validate phone numbers before selling them to telemarketers and spam operators. Once 0291298812 confirms your line is active, you may see an increase in unwanted sales and promotional calls.
Will my number be sold if I answer a silent call from 0291298812?
Possibly. The contributor who answered 02 9129 8812 expressed concern that answering confirmed their number was active, making it more valuable to telemarketers. Avoiding unknown calls and letting them go to voicemail is safer than confirming your number works. If you did answer 0291298812, blocking the number now can help reduce follow-up spam.
Is 02 9129 8812 connected to a legitimate business?
02 9129 8812 is registered as a local service number through NetSIP Pty Ltd in NSW, but the silent call pattern reported by the contributor suggests it is being used for automated testing rather than legitimate business communication. Many spam operators use VoIP providers like NetSIP to make silent calls, so the registration does not guarantee legitimacy.
What should I do if 0291298812 calls me?
Do not answer. Let calls from 02 9129 8812 go to voicemail. If you accidentally answer 0291298812, hang up immediately without saying anything. Then block the number in your phone settings to prevent future calls. Blocking 02 9129 8812 now is more effective than engaging with the caller.
Why is 02 9129 8812 hanging up when I answer?
The contributor's experience with 02 9129 8812 shows the call disconnected as soon as it was answered, which is consistent with automated validation systems. These systems use silent calls to test whether numbers are active, then immediately hang up. If you see repeated calls from 0291298812 or similar patterns, your number has likely been flagged as active.
Should I call back 02 9129 8812?
No. Do not return calls to 02 9129 8812. Calling back 0291298812 confirms your number is active and monitored, increasing the likelihood of follow-up spam. If you receive calls from 02 9129 8812, block it and report the activity to ACMA via acma.gov.au instead of engaging with the caller.
