WRITE A REVIEWFrequently Asked Questions
Why do I keep getting silent calls from 02 7247 5451?
Silent calls with hold music are typically automated callback scams testing if your number is active. Once confirmed, scammers may target the number with follow-up calls claiming to be from banks, government agencies, or tech support. The callback scam profit model relies on recipients dialling back a premium rate line. Block 0272475451 immediately to avoid further contact.
Is 02 7247 5451 a legitimate business number?
The number 02 7247 5451 is allocated as a local NSW service through Symbio Networks, but a legitimate business would never call without leaving a message or identifying themselves. The silent call with hold music pattern reported by the contributor is a hallmark of scam activity, not standard business practice. If you're expecting a call from a genuine business, ring them back using a number you find independently on their official website.
What happens if I return a call to 0272475451?
Returning a call to 0272475451 after a silent call is exactly what callback scammers want. You may be connected to a premium rate line that charges you per minute, or the call may be recorded to verify your number is active for future scam targeting. Never return calls from numbers that contacted you with only silence or hold music.
How do I block 02 7247 5451 on my phone?
On most Australian phones, you can block 02 7247 5451 by opening the recent calls list, selecting the number 0272475451, and choosing 'Block' or 'Report as Spam'. iPhone users can add the number to their blocked contacts; Android users can enable 'Block Unknown' in call settings. Check your phone provider's support page for specific blocking instructions, as older landlines may require different steps.
Should I report 02 7247 5451 to the ACMA?
Yes. If you receive multiple calls from 02 7247 5451 or 0272475451, report it to the Australian Communications and Media Authority (ACMA) via acma.gov.au. Even a single silent call is worth reporting, as patterns emerge when many contributors file complaints about the same number. ACMA uses these reports to investigate and take action against repeat offenders.
