Robocall and Silent Call Reports for 02 7234 1800
Four contributors have reported calls from 02 7234 1800 (also written as 0272341800) exhibiting robocall and silent call behaviour. The number is registered as a local service with NetSIP Pty Ltd in NSW. Reports describe a consistent pattern where the number rings repeatedly but disconnects immediately when answered, or remains silent before the call drops, with no voicemail ever left behind.
The behaviour suggests an automated calling system rather than a person attempting to reach the recipient. Contributors note that 0272341800 continues to call despite never communicating any message or purpose, which is characteristic of callback scam systems or abandoned outbound dialling campaigns.
What Happens When You Answer Calls from 02 7234 1800
When contributors pick up calls from 02 7234 1800, they encounter either complete silence or the line disconnects within seconds. One contributor described the brief sound as "sounds like dodgy call centre," suggesting possible automated systems or poorly managed outbound dialling infrastructure on the other end.
The absence of any voicemail or callback information indicates this is not a legitimate business trying to reach you. Legitimate callers leave messages or provide contact details. The repeated nature of calls from 0272341800 combined with instant disconnection is a known tactic used by scammers testing whether a number is active and will answer calls, feeding those details back into callback scam databases.
Calling Patterns and Frequency
Reports about 02 7234 1800 span from late January through early February 2026. One contributor reported "keeps ringing off the hook," indicating multiple calls over a short period. The calls arrive at varied times including early morning (05:23) and mid-morning (10:13, 10:42), suggesting automated systems rather than human operators working standard business hours.
Contributors receiving calls from 0272341800 describe the experience as persistent and frustrating, with each attempt following the same pattern: ring through, hang up on answer, no message. This repetition without variation is typical of callback verification systems used in scam operations to confirm active phone numbers.
What to Do If You Receive a Call from 02 7234 1800
If 02 7234 1800 calls you:
- Do not: Answer the call or return it, as this confirms your number is active to scammers
- Do: Let it go to voicemail, block the number immediately, and do not engage if you answer by mistake
- Do: Hang up instantly if you hear silence or automated sounds
- Do: Never press any buttons or speak, as this may activate callback protocols
- Do: Consider enabling "Unknown Callers" blocking on your phone if available
The key strategy is to avoid confirming your number is active. Once a scammer's automated system determines 0272341800 reaches a live person, your number may be circulated within scam networks and sold to multiple operations.

WRITE A REVIEWFrequently Asked Questions
Why does 02 7234 1800 keep calling but hang up when I answer?
Robocall systems like the one calling from 02 7234 1800 (0272341800) are designed to test whether phone numbers are active and will answer calls. When you pick up, the system knows your number is real and you respond to calls, which increases its value in scam databases. The automated system then disconnects and moves to the next number. This is called "call verification" or a callback scam probe. Do not answer future calls from 0272341800.
Should I try to call back 02 7234 1800?
No. Never call back 02 7234 1800 or 0272341800. If you return the call, you confirm to the robocall system that your number is active and that you will initiate contact, which makes your number even more valuable for sale to scammers. Calling back also exposes you to potential fraud or unexpected charges. Block the number and let it go to voicemail if it calls again.
What does it mean if 02 7234 1800 leaves no voicemail?
Legitimate businesses always leave voicemail messages explaining why they called. The fact that 02 7234 1800 (also 0272341800) calls repeatedly but never leaves a message is a strong sign it's an automated robocall or callback scam system with no legitimate purpose. Real creditors, services, or organisations need to communicate a reason for calling. The silence indicates the caller does not want to be identified or does not have a genuine customer service reason.
Is 02 7234 1800 a callback scam?
The behaviour reported by contributors about 02 7234 1800 is consistent with callback scam probing. These systems automatically dial thousands of numbers to identify which ones are active and will answer. When you respond, the system confirms your number works and sells that data to scammers who later call back claiming to be from banks, the ATO, or NBN. Block 0272341800 and do not engage with any follow-up calls.
Can I block 02 7234 1800 on my phone?
Yes. On most smartphones, you can block 02 7234 1800 directly from your call log or contacts. In Australia, your phone provider may also offer call filtering options that block suspected robocalls and spam. Contact your provider to ask about free robocall filtering. Additionally, register your number on the Do Not Call Register at donotcall.gov.au, though robocall systems often ignore this list. Blocking 0272341800 is your most effective immediate defence.
