Telstra Impersonation Scam on 03 8747 3591
A contributor received a call from 03 8747 3591 (also written as 0387473591) where the caller impersonated a Telstra representative. The caller claimed the recipient's IP address was open and exposed, a common social engineering tactic designed to create urgency and concern about network security.
What's notable about this 0387473591 call is the caller's immediate exit when challenged. The contributor wisely suggested they would verify the claim by calling official Telstra back directly. Rather than continue the conversation or provide verification details, the caller simply hung up. This behaviour is consistent with scammers who cannot withstand basic authentication checks.
What the Caller from 03 8747 3591 Claimed
The contributor reported that the caller from 03 8747 3591 used a technical pretext, stating the recipient had an open IP address. This claim was designed to prompt the recipient to take immediate action, likely to download remote access software, share login credentials, or provide payment for a fake security fix.
The brevity of the interaction with this number (0387473591) suggests the caller was testing whether the recipient would engage with the premise. Once resistance appeared, the scammer disconnected rather than escalate or attempt persuasion tactics typical of more persistent fraud campaigns.
Why This Telstra Impersonation Matters
Telstra impersonation scams targeting 03 8747 3591 callers rely on legitimate consumer concerns about internet security and network safety. By claiming to represent Australia's largest telecommunications provider, scammers leverage the trust associated with the Telstra brand. The technical jargon about IP addresses adds false credibility.
The allocation data shows 0387473591 is registered as a local service through Symbio Networks in Victoria. This legitimate infrastructure makes the impersonation more convincing, as the call appears to originate from within Australia rather than offshore.

WRITE A REVIEWFrequently Asked Questions
Why did the caller from 03 8747 3591 hang up so quickly?
Scammers often disconnect immediately when challenged or asked to verify through official channels. The caller from 03 8747 3591 (0387473591) could not provide legitimate verification because the claim was false. This behaviour - hanging up when confronted - is a strong indicator of a scam and differs from genuine Telstra support, who would have verification procedures and would not disconnect.
Is 0387473591 really a Telstra number?
No. While 03 8747 3591 is allocated as a local service in Victoria through Symbio Networks, this does not mean it is a legitimate Telstra line. Scammers can use any phone number to call and claim any identity. Telstra will never call you unsolicited about security issues. Always hang up and call Telstra back using the official number on your bill or telstra.com.au.
What does 'open IP address' mean, and should I be concerned?
An open IP address is technical jargon used to create false urgency. Callers from 03 8747 3591 use this claim because it sounds technical and serious, even though it rarely requires emergency action. Legitimate technology providers do not contact customers unsolicited about IP security issues. If you have genuine security concerns, contact your service provider directly using their official website, not by calling back a number that just called you.
Should I call 03 8747 3591 back to verify the caller's claims?
No. Never call back the number that called you about a security issue. Scammers may have spoofed 0387473591 or use it as a callback trap. If you're concerned about a legitimate security claim, independently contact your service provider using the number on your bill or their official website. This ensures you reach genuine support staff, not the scammer.
What should I do if I already engaged with the caller from 0387473591?
If you provided personal information, passwords, or allowed remote access during a call from 03 8747 3591, take immediate action: change your passwords, contact your bank and service providers, monitor your accounts for suspicious activity, and consider enabling two-factor authentication. Report the incident to Scamwatch (scamwatch.gov.au) and ACMA (acma.gov.au). Document the exact time and details of the call from 0387473591 for your records.
How can I block 03 8747 3591 on my phone?
Most Australian phones allow you to block numbers directly. In your phone's call history or contacts, select the number 03 8747 3591 (0387473591), choose 'Block' or 'Block this number,' and confirm. You can also add it to a spam filter if your phone has one. Once blocked, calls from 03 8747 3591 will not ring through, though you may still receive voicemails. If the scammer calls from a different number, repeat the blocking process.
