AI Robocall and Callback Scam Reports for 04 8391 3411
Three contributors have flagged 04 8391 3411 (also written as 0483913411) for automated robocalls using artificial intelligence technology. The reports indicate a coordinated campaign involving realistic-sounding AI voices and callback request tactics. This Optus mobile number has triggered multiple reports within a short timeframe, suggesting an active campaign targeting Australian phone numbers.
What makes these calls distinctive is the sophistication of the AI voice quality. One contributor described the caller as "incredibly real" with an American accent, pitching for an outsourcing firm. The realistic presentation appears designed to bypass initial caller suspicion, making it more likely recipients will engage or return calls.
What Callers from 04 8391 3411 Say
Reports about 0483913411 describe two primary call patterns. In one scenario, an AI bot identified as "Ryan" called the same person twice, promoting outsourcing services with a convincing American accent. The caller's persistence across multiple attempts suggests automated dialling with callback targeting.
A second report mentions a robocall voicemail message that simply requests the recipient call back, with no introductory content or legitimate business purpose stated. This callback request tactic is particularly concerning because it aims to trick recipients into initiating contact, potentially incurring costs or exposing themselves to follow-up scams. The voicemail approach represents a common evasion technique where scammers avoid leaving identifying information, making it harder to trace the original purpose.
Report Patterns and Timing
Contributors received calls from 04 8391 3411 across different channels and timeframes. One person answered the call directly and heard the AI bot pitch twice from the same number. Another received a robocall voicemail requesting a callback. A third contributor answered and reported the interaction as a nuisance AI robocaller.
The reports span from August 2025 through April 2026, indicating sustained activity rather than isolated incidents. The repeated-calls tactic documented in one report suggests this number may be part of a list of Australian mobile numbers targeted for sequential contact attempts, a common strategy for outsourcing scams and investment fraud campaigns.

WRITE A REVIEWFrequently Asked Questions
Why is the AI voice on calls from 04 8391 3411 so realistic?
One contributor noted the AI bot named "Ryan" sounded "incredibly real and American," which is a deliberate tactic. Modern AI voice technology (text-to-speech synthesis) can now produce near-human speech quality, making it harder for recipients to immediately recognise they're talking to a bot. Scammers use realistic voices to bypass initial scepticism and keep people on the line longer. If you notice the caller doesn't respond naturally to questions or repeats phrases, or if the call sounds too polished, it's likely an AI robocall from 0483913411 or similar numbers.
What should I do if 04 8391 3411 keeps calling me multiple times?
One contributor received calls from 04 8391 3411 multiple times, which indicates the number is using automated dialling lists. Block the number immediately in your phone settings after the first call. If it continues from different numbers, contact your mobile provider (Optus) and ask about call filtering or spam-blocking tools. Report the repeated calls to ACMA at acma.gov.au, as multiple calls from the same number within a short timeframe is a pattern they monitor for active scam campaigns.
Is it safe to return a call to a voicemail from 0483913411?
No. Reports about 04 8391 3411 include voicemails requesting callbacks with no clear business purpose or introduction. This is a deliberate scam tactic designed to make you initiate the contact, which can incur costs or expose you to follow-up fraud attempts. Never return calls from 0483913411 voicemails. Delete them and block the number.
How can I tell if a call from 04 8391 3411 is an AI robocall?
Several signs indicate you're dealing with an AI robocall from 0483913411: the voice sounds very smooth and polished with an accent (reports describe an American accent), there are slight delays or unnatural pauses between your words and the response, the caller repeats phrases or doesn't respond naturally to interruptions, or the call transitions abruptly between different topics or to recorded messaging. If you suspect it's a bot, hang up immediately.
What outsourcing scams use numbers like 04 8391 3411?
One contributor reported an AI bot from 04 8391 3411 pitching "for an outsourcing firm," but didn't provide details about the specific company name or offer. Outsourcing scams often target business owners and self-employed people, claiming to offer cost-saving services or overseas staffing solutions. They're frequently the entry point for follow-up investment or employment scams. If contacted from 0483913411 or similar numbers with outsourcing pitches, do not engage, hang up, and report to Scamwatch at scamwatch.gov.au.
Should I report 04 8391 3411 to my mobile provider?
Yes. Since 04 8391 3411 is an Optus mobile number, contact Optus customer service and report the robocalls. Optus has spam-filtering tools and can flag the number for investigation. Additionally, report to ACMA (acma.gov.au) and Scamwatch (scamwatch.gov.au) so the reports are centrally tracked. When you report 0483913411, mention the AI bot name "Ryan," the repeated calls, and the callback request voicemail so authorities understand the full scope of the campaign.
