Robocall Reports for 04 8500 7751
Two contributors have reported receiving robocalls from 04 8500 7751 (also written as 0485007751), a mobile number on the Optus network. Both reports describe automated calls with American-accented voices claiming affiliation with obscure companies and attempting to prompt button presses for unknown purposes.
The pattern suggests an international robocalling operation using Australian mobile numbers as spoofing points. Contributors who called back 0485007751 encountered a fully automated system, indicating no genuine customer service capability behind this number.
What Callers from 04 8500 7751 Say
According to community reports, the robocall system references a company with an unclear name (reported phonetically as "kock-eyn" or similar). The automated voice requests callers to press buttons to proceed, but neither contributor disclosed what action they were being prompted to take.
The key indicator of scam activity is that 04 8500 7751 exhibits zero human interaction capability. When contributors called back the number, they reached only the robotic system - no customer service, no operator transfer, and no ability to speak with a real person or verify the company's legitimacy. This is a hallmark of illegitimate robocalling operations.
Report Patterns
Both reports of 0485007751 came within hours of each other in early January 2026, suggesting a concentrated calling campaign. Each contributor who answered received an automated message with poor call quality, making the initial contact difficult to understand - likely intentional to discourage detailed attention.
The robocall system appears designed to harvest responses from people willing to press buttons, often an indicator that subsequent calls will target the same number with refinement of the scam pitch or escalation to financial requests.

WRITE A REVIEWFrequently Asked Questions
Why does a robocall use an Australian mobile number like 04 8500 7751?
Scammers spoof local numbers because Australians are more likely to answer calls from domestic mobile numbers than international ones. The number 0485007751 may be compromised, inactive, or sold to robocalling operators. Reporting 04 8500 7751 to Optus and ACMA helps shut down the abuse.
What happens if I press the buttons the robocall from 04 8500 7751 requests?
Contributors to Reverseau didn't disclose what button presses on 0485007751 would trigger, but robocalls typically use button responses to: confirm your number is active (leading to more calls), route you to a live scammer, or charge fees. Never press buttons on any unsolicited robocall.
Should I call 04 8500 7751 back to find out who it is?
No. Calling back 0485007751 confirms your number is monitored and active, which often increases robocall frequency. Both contributors who called back 04 8500 7751 reached only automated systems with no legitimate business information available.
Could 04 8500 7751 be a legitimate company with a technical issue?
Unlikely. Legitimate Australian businesses use professional phone systems with human operators, proper call quality, and clear identification. The robocall from 0485007751 has none of these. Real companies don't ask callers to press buttons without explaining why.
How do I stop robocalls to my number after receiving one from 04 8500 7751?
Block 0485007751 immediately in your phone settings. Register your number with the Do Not Call Register at donotcall.gov.au - this applies to legitimate telemarketers but won't stop illegal robocallers. Report the number to ACMA (acma.gov.au) to help authorities track the operation.
Is the Optus mobile number 04 8500 7751 actually owned by the company calling?
Not necessarily. Optus numbers like 0485007751 can be compromised, reassigned, or illegally spoofed. This is why reporting to both ACMA and Optus is important - they can investigate whether the number was stolen, sold, or misused by the robocalling operation.
