Silent Call and Robocall Reports for 02 7241 7525
Two contributors have reported calls from 02 7241 7525 (also written as 0272417525) displaying characteristics of automated calling systems. The most recent report describes a silent call where the recipient answered to complete dead air before disconnection - a hallmark of robocall technology testing active numbers. This number is allocated as a local Sydney service through Symbio Networks Pty Ltd in NSW.
One contributor noted that 0272417525 appears to be spoofing a legitimate Sydney area code, using the 02 7241 prefix to present as a local contact. This spoofing tactic exploits caller ID trust, increasing the likelihood that recipients will answer.
What Callers from 02 7241 7525 Do
The behaviour reported from 02 7241 7525 is characteristic of unattended robocall systems rather than human-initiated contact. When answered, callers experienced immediate dead air with no voice prompt, no company identification, and no callback message - the call simply disconnected.
A separate voicemail from this number contained only a female voice speaking in Chinese. Apple's automated transcription could not reliably interpret the content, suggesting either poor audio quality, regional dialect variation, or deliberately obscured messaging. The contributor was unable to determine the caller's identity or purpose from the voicemail on 0272417525.
Report Patterns and Timing
Both reports arrived within a year of each other, with the silent call occurring most recently in February 2026. The voicemail was received in March 2025. The timing gap and different communication methods (live call versus voicemail) suggest either repeated calling campaigns or multiple sources using spoofed Sydney numbers in the 02 7241 range.
Contributors did not report multiple calls from the same number, though silent call campaigns typically involve high-volume dialling across many numbers to identify active lines for follow-up targeting.
What to Do If You Receive a Call from 02 7241 7525
If 02 7241 7525 calls you:
- Do not: Answer if you don't recognise the number, return the call, or press keys to "speak to someone" (confirms your number is active)
- Do: Let it ring to voicemail, block the number immediately, and do not engage with any follow-up contact
- Silent calls: Hanging up is correct - do not wait on the line or respond to prompts
- Unknown voicemails: Do not return the call; instead, block and report the number
Robocalls that result in dead air are often part of automated dialling systems that test which numbers are connected to active accounts. Responding to or engaging with such calls confirms your number is monitored and may lead to escalated targeting.

WRITE A REVIEWFrequently Asked Questions
What is a silent call from 02 7241 7525?
A silent call occurs when you answer 02 7241 7525 and hear only dead air before the line disconnects. This is typically generated by robocall systems that automatically dial numbers to detect active accounts. The system hangs up because no human operator is assigned to handle the call. Do not respond or remain on the line - simply hang up and block 0272417525.
Why did I get a voicemail in Chinese from 02 7241 7525?
The voicemail from 02 7241 7525 was in Chinese and unintelligible to the recipient, even with automated transcription. This could indicate a misdirected call, spoofed number, or deliberately obscured messaging. Without understanding the content, you cannot verify the caller's identity. The safest approach is to treat it as unverified contact - do not return the call. If you receive similar calls, block 0272417525 and report to ACMA.
Is 02 7241 7525 spoofing a real Sydney number?
Yes. The number 02 7241 7525 is allocated as a local Sydney service through Symbio Networks, but contributors report it appears to be spoofed for robocalling purposes. Scammers and robocallers often use legitimate-looking local numbers to increase answer rates. Just because 0272417525 displays as a Sydney number does not mean the actual caller is in Sydney or represents the listed provider. Do not assume legitimacy based on the area code.
Should I call back 02 7241 7525 to find out who it is?
No. Do not call back 02 7241 7525 or 0272417525. If it was a silent call, calling back will connect you to an unattended robocall system or not reach anyone. If you want to verify a legitimate contact, call the organisation directly using a phone number from their official website - never use a number from an unknown caller. Calling back unknown numbers also confirms to the caller that your number is active.
What should I do if I keep receiving calls from 02 7241 7525?
Block 02 7241 7525 on your phone immediately. Register your number at donotcall.gov.au to reduce telemarketing and automated calls (though silent calls may persist). Report the number to ACMA at acma.gov.au if calls are repeated. Report your experience with 0272417525 on Reverseau to help other Australians. Most robocall campaigns move through numbers quickly once they confirm you are monitoring - blocking and not engaging will discourage further attempts.
Why is 02 7241 7525 making robocalls if it's allocated to Symbio Networks?
The allocation to Symbio Networks is what the phone number is registered to, but this does not mean Symbio Networks is making the calls. Robocallers frequently spoof legitimate provider numbers or compromise accounts to send calls. Symbio Networks is not responsible for the behaviour reported. If you believe the provider's account has been compromised, you can contact them directly to report 0272417525 abuse, but your primary action should be blocking the number and reporting to ACMA.
