Community reports for 02 9145 8100 (0291458100): Silent calls that hang up immediately, brief rings with no voicemail, and spam offers from Sydney NSW.
Silent Calls and Nuisance Activity from 02 9145 8100
Three contributors have reported unwanted contact from 02 9145 8100 (also written as 0291458100), a Sydney NSW local number allocated to NetSIP Pty Ltd. The pattern centres on silent calls that disconnect without engagement, mixed with sporadic spam activity. One contributor specifically noted receiving a silent call from this number - the caller hung up immediately after they answered, with caller ID confirming the Sydney origin of 02 9145 8100.
The behaviour suggests a combination of nuisance calling tactics rather than a focused scam operation. Two of the three reports involve brief contact that leaves no voicemail, while one contributor described receiving what they characterised as a "dodgy deal" similar to other known spam numbers, indicating potential connection to broader telemarketing or promotional campaigns.
What Callers from 02 9145 8100 Do
Silent calls dominate the report pattern for 0291458100. One contributor described the caller hanging up immediately after the recipient answered - no greeting, no message, just disconnection. Another reported the number ringing for only 5 seconds before disconnecting automatically, leaving no voicemail message. This type of behaviour is typical of automated systems testing whether a number is active, or nuisance callers who disconnect when a real person answers.
A third report mentions spam activity with promotional content described as matching patterns from other flagged numbers, suggesting the line may be part of a wider telemarketing network rather than a standalone nuisance caller.
Report Patterns and Timing
The three reports for 02 9145 8100 span several months, with activity recorded as recently as March 2026. One call occurred during evening hours (20:39 on 31 March 2025), while another came through during early morning (05:32 on 26 March 2026). The varied timing suggests either automated systems running on set schedules or multiple operators using the same line.
All three reports originate from NSW, consistent with the number's Sydney local allocation. The mix of silent calls and spam activity indicates this line is not a simple one-off nuisance but part of ongoing problematic calling behaviour.

WRITE A REVIEWFrequently Asked Questions
Why does 02 9145 8100 hang up immediately when I answer?
This is a common nuisance tactic. Contributors report that 0291458100 either hangs up instantly or rings for only a few seconds before disconnecting. This type of behaviour typically indicates either an automated dialler testing if your number is active, or a caller who disconnects when a real person answers rather than an answering machine. Do not call the number back, as this confirms your number is monitored.
Is 02 9145 8100 a legitimate Sydney business?
The number is allocated to NetSIP Pty Ltd as a local Sydney service, but community reports indicate it is being used for silent calls and spam activity. While NetSIP is a telecommunications provider, this does not guarantee the caller using 02 9145 8100 is operating legitimately. Many spam and nuisance operators use legitimate telecom allocations to disguise their origin.
What should I do if I keep getting calls from 0291458100?
Block the number immediately on your phone. If calls persist after blocking, report the number to ACMA at acma.gov.au and lodge a complaint about repeated contact. You can also register on the Do Not Call Register at donotcall.gov.au, though this may not stop illegal nuisance callers using 02 9145 8100.
Are silent calls from 02 9145 8100 dangerous?
While silent calls from 02 9145 8100 are annoying rather than immediately dangerous, they indicate your number has been flagged as active. This can lead to more targeted spam or scam attempts in future. Never press keys or speak during silent calls, as this confirms your number to the caller and may increase contact frequency from 0291458100 and similar numbers.
Can I report 02 9145 8100 to my phone provider?
Yes. Contact your phone provider and report the number 0291458100 as a nuisance caller. Some providers offer enhanced call blocking features. You should also report to ACMA at acma.gov.au, as they have authority to investigate breaches of the Do Not Call Rules and can take action against operators misusing numbers like 02 9145 8100.
Why do nuisance callers use real business allocations like 02 9145 8100?
Operators using 0291458100 often source real telecom allocations to appear more legitimate and bypass initial caller ID filters. NetSIP Pty Ltd's legitimate allocation makes the number appear trustworthy at first glance, but this does not mean all calls from 02 9145 8100 are authorised by the company. Report suspicious activity to both ACMA and your provider so they can investigate misuse.
