Nuisance Call Report for 02 9933 3301
A single contributor has reported receiving a nuisance call from 02 9933 3301 (also written as 0299333301). The caller said hello, but when the contributor responded, there was silence on the line, prompting an immediate hang-up. This type of call pattern is commonly associated with either accidental dialling, callback scam testing, or automated systems fishing for active phone numbers.
What Happened on the Call
The contributor who answered 02 9933 3301 described a brief interaction where the caller simply said hello. Rather than continuing conversation or identifying themselves, the line went silent when the recipient replied. This behaviour is typical of nuisance calls where the caller appears uncertain or where automated systems are testing line validity. The contributor's quick action to hang up prevented any further interaction.
Call Timing and Source
The call to 0299333301 was received and answered, with the report lodged in April 2026. The number is allocated as a local Telstra service in NSW, which means it appears to originate from a standard Australian phone line rather than an overseas source or obvious VOIP service. However, legitimate numbers can be spoofed, so allocation data alone does not guarantee authenticity.
What to Do If You Receive a Call from 02 9933 3301
If 02 9933 3301 calls you:
- Do not: Provide personal information, return the call, or engage in lengthy conversation
- Do: Let unknown calls go to voicemail, block the number if calls repeat, and verify any claimed identity through official channels using a separate phone line

Understanding Nuisance Calls
Nuisance calls come in many forms. Some are accidental misdials, others are deliberate testing calls checking whether your phone number is monitored or active. Silent calls where someone hangs up after you answer can indicate callback scam preparation, where scammers are building lists of working numbers to contact later with a specific pitch. The fact that 02 9933 3301 produced silence rather than a sales pitch or scam narrative suggests this may be reconnaissance rather than an active scam attempt at the time of the call.

WRITE A REVIEWFrequently Asked Questions
What does it mean when someone calls from 02 9933 3301 and just says hello then goes silent?
Silent calls after initial greeting are often used to test whether your number is active and monitored. Scammers and automated systems use this tactic to build lists of working phone numbers for follow-up contact. The contributor who received this call from 02 9933 3301 did the right thing by hanging up immediately rather than responding further.
Should I call back 0299333301 if they don't leave a voicemail?
No. Never return calls to unknown numbers, especially those that hang up on you. Calling back 0299333301 could confirm your number to a scammer or activate premium services. If the call was legitimate, they will leave a voicemail or try again.
Is 02 9933 3301 definitely a scam because it's a local NSW Telstra number?
Not necessarily. The fact that 02 9933 3301 shows as a Telstra local number in NSW does not prove legitimacy. Legitimate numbers are frequently spoofed by scammers, and actual local numbers can be compromised. Judge the call by behaviour and context, not by how it appears to be allocated.
What should I do if 0299333301 keeps calling me?
If calls from 02 9933 3301 become repeated or harassing, block the number on your phone immediately. You can also report it to ACMA at acma.gov.au or lodge a complaint with your phone provider, Telstra. Share your experience on Reverseau so other contributors know about 0299333301.
Could the call from 02 9933 3301 have been accidental?
It's possible. Accidental misdials do happen, and one silent call does not indicate a pattern. However, if you receive multiple calls from 0299333301 with the same behaviour, it's more likely to be deliberate testing or scammer reconnaissance rather than repeated accidents.
How do I block 02 9933 3301 on my phone?
Most Australian mobile phones allow you to block numbers through Settings. On iPhone, use the Phone app to find 02 9933 3301 in recent calls, tap it, and select 'Block this Caller'. On Android, open Phone app, find 0299333301 in call history, press and hold, then select 'Block number'. You can also ask your provider, Telstra, to block 02 9933 3301 at the network level.
