Impersonation and Robocall Reports for 03 4051 8571
Contributors have flagged 03 4051 8571 (also written as 0340518571) for suspicious activity involving number spoofing and automated calls. The reports indicate this number is being used as part of a coordinated impersonation scheme falsely claiming affiliation with Symbio Networks, a legitimate Australian telecommunications provider. One contributor identified a network of spoofed numbers allegedly linked to Symbio Networks, including 02 7241 3924, 03 4051 8571, and 03 8657 0597.
A separate report about 0340518571 describes an automated robocall delivering a recorded message in Mandarin, suggesting the caller network is targeting multilingual audiences with persistent contact attempts.
What Callers from 03 4051 8571 Are Doing
Reports about 03 4051 8571 reveal two distinct attack patterns. The first involves callers spoofing legitimate Symbio Networks numbers to add false credibility to their contact attempt. The contributor who received this call recognised the impersonation tactic and blocked the number immediately.
The second pattern involves automated robocalls in Mandarin language. The recorded message claims the caller has attempted contact multiple times regarding an unspecified document and prompts the recipient to press 1 for English or 2 for Chinese. This callback-request tactic is designed to create urgency and pressure recipients into responding to an unknown caller.
Report Patterns and Timing
Both reports came from answered calls to 03 4051 8571, indicating the number actively reaches through to recipients. The robocall report specifically mentions the automated system claims repeated previous contact attempts, a common pressure tactic used in scam campaigns to create a false sense of obligation. Contributors received these calls despite no prior legitimate business relationship with either the spoofed Symbio Networks or the actual caller organisation.

WRITE A REVIEWFrequently Asked Questions
Why would a scammer spoof a Symbio Networks number like 03 4051 8571?
Spoofing legitimate telecommunications provider numbers makes the scammer's call appear more credible and trustworthy. Recipients are more likely to answer or engage with a number they recognise as belonging to a real company. The contributor who reported 03 4051 8571 recognised this tactic and blocked the number, but others may not catch the impersonation immediately. Always verify by contacting the company directly using a number from their official website.
What does it mean when a robocall claims to have called me multiple times before?
This is a pressure tactic designed to make you feel obligated to respond. The automated message from 0340518571 claiming previous contact attempts creates artificial urgency. In reality, the robocall system likely hasn't called your number before, or if it has, the repeated attempts are intentional harassment. Do not press any buttons or return the call as this confirms your number is active and may result in more contact.
Is 03 4051 8571 actually owned by Symbio Networks?
The allocation data shows 03 4051 8571 is registered to Symbio Networks as a local service number in Victoria. However, one contributor specifically identified that this number (along with 02 7241 3924 and 03 8657 0597) is being spoofed by scammers. Number spoofing allows criminals to make their calls appear to come from legitimate numbers. If you receive a suspicious call claiming to be from Symbio Networks, hang up and call Symbio directly on their official number.
What document was the robocall from 0340518571 referring to?
The robocall message from 03 4051 8571 mentioned 'some document' but never specified what it was. This vagueness is intentional - scammers use generic references to documents, packages, accounts, or debts to prompt you to press a button or return their call. Once you respond, they can social engineer more specific information from you or attempt to access your personal details. Never engage with a robocall that won't clearly explain its purpose upfront.
Should I be concerned that the robocall was in Mandarin?
The Mandarin-language robocall from 03 4051 8571 indicates the scammer is targeting multilingual communities. This is a common tactic to reach specific populations and may suggest they have access to databases segmented by language preference or cultural background. The fact that the call offered English or Chinese options (press 1 or 2) shows this is a targeted campaign. Report this number to ACMA at acma.gov.au to help protect other Mandarin-speaking Australians from this scam.
What should I do if I already pressed a button on the 03 4051 8571 robocall?
If you pressed 1 or 2 on the robocall from 0340518571, hang up immediately if you haven't already. Do not provide any personal information, banking details, or passwords. Block the number and monitor your accounts for suspicious activity. If a live person answers after you press a button, hang up without speaking. Report the call to ACMA and Scamwatch. Consider placing a fraud alert with your bank if you're concerned, and monitor your credit file through equifax.com.au or other credit reporting bodies.
