Tech Support Impersonation Reports for 02 7239 9010
Two contributors have flagged calls from 02 7239 9010 (also written as 0272399010) for suspicious activity. One report describes a caller claiming to be a Telstra employee, referencing technical issues with the recipient's IP address to create a false sense of urgency. Another contributor received a call from 02 7239 9010 where no one responded when they answered, a common tactic used to verify active phone numbers for follow-up scam attempts.
The impersonation report about 0272399010 is particularly concerning because the caller used specific technical terminology (IP address status changes) to sound legitimate. This type of social engineering preys on people's unfamiliarity with network terminology and creates panic about their internet connection being compromised.
What Callers from 02 7239 9010 Claim
According to the scam report, the caller from 02 7239 9010 claimed to be contacting from Telstra and stated that the recipient's IP address had switched from private to public. The caller then offered to help resolve this alleged issue. This is a classic tech support scam opener designed to create technical-sounding urgency without requiring the victim to understand what an IP address actually is.
The silent call from 0272399010 involved no voice interaction - the caller simply hung up or remained silent when the number was answered. Contributors experiencing this pattern often report a strong intuition that the call was malicious, which frequently aligns with robocall or callback verification tactics used by scammers.

The two reports for 02 7239 9010 occurred within a short timeframe in mid-January, with the Telstra impersonation call arriving in the early morning hours (around 1am) and the silent call occurring the following morning. This timing pattern is typical of automated calling systems that operate across different batches of phone numbers.
The provider allocation data shows 02 7239 9010 is registered to Symbio Networks in NSW as a local service number, which makes the Telstra impersonation claim particularly suspect - legitimate Telstra support would typically display as an official Telstra number.

WRITE A REVIEWFrequently Asked Questions
What does it mean if a caller claims my IP address switched from private to public?
It's almost certainly a scam. One contributor who received a call from 02 7239 9010 reported exactly this claim. Telstra and other legitimate ISPs don't call customers about IP address status changes, and the technical language is designed to confuse and create false urgency. Hang up immediately and contact Telstra directly using the number on your bill to verify your account is fine.
Why would someone call me from 02 7239 9010 and then hang up?
A silent call from 0272399010 is typically used to verify your phone number is active and answered by a real person. Scammers and spam operations use these to confirm they have valid numbers before launching follow-up scam campaigns. If you answer and hear silence, don't say anything - just hang up and block the number.
Is 02 7239 9010 actually a Telstra number?
No. The number 02 7239 9010 is registered to Symbio Networks as a local service number in NSW, not Telstra. This is why the Telstra impersonation claim in the scam report is so suspicious - scammers often spoof or use unrelated numbers to seem legitimate. Always verify by calling Telstra directly on a known official number.
What should I do if I already gave information to the caller from 02 7239 9010?
If you provided personal details, account information, or agreed to remote access, contact your internet provider immediately using the official number on your bill. Monitor your accounts for suspicious activity and consider changing passwords. Report the incident to Scamwatch at scamwatch.gov.au and ACMA at acma.gov.au so they can track 0272399010.

Will blocking 02 7239 9010 prevent future calls from this number?
Blocking 0272399010 will stop calls from this specific number, but scammers often use multiple numbers in sequence. After receiving a call from 02 7239 9010, expect similar calls from other similar numbers.
