Robocall Reports for 03 9003 3520
A contributor has reported receiving a robocall from 03 9003 3520 (also written as 0390033520). The call left a voicemail containing what the contributor described as a strange AI-generated message followed by silence. This pattern suggests automated calling activity rather than a live operator.
Robocalls to 0390033520 of this type often indicate either spam screening tests, abandoned dialler capacity, or early-stage scam probing. The AI voice combined with silence may be used to identify active phone numbers for later targeting with more sophisticated scam attempts.
What the Robocall from 03 9003 3520 Contained
The voicemail message was AI-generated rather than a recording of a human voice. After the initial message, the contributor noted silence on the line rather than further audio or a prompt to press a number. This combination is typical of robocalling systems that test number validity or gather engagement metrics.
The contributor did not report any claims, requests for money, or threats in the message left on 0390033520. However, the unusual nature of the call and the use of automated technology warrant caution if additional contact attempts occur from this number.

WRITE A REVIEWFrequently Asked Questions
What is a robocall and why did I receive one from 03 9003 3520?
A robocall is an automated phone call using pre-recorded messages or AI-generated speech rather than a live operator. The robocall to 03 9003 3520 (0390033520) in this case left an AI message followed by silence, which is typical of systems testing whether numbers are active. Scammers and spam operators use robocalls to identify valid phone numbers for later targeting with more complex scams.
Should I call back 03 9003 3520 to find out what the message said?
No. Do not call back 0390033520. Returning the call confirms to the robocaller that your number is monitored and active, which typically results in more frequent contact attempts. If you want to understand the message, listen to your voicemail recording again rather than calling the number that contacted you.
Is 03 9003 3520 definitely a scam?
Based on one report, 0390033520 displayed robocall characteristics (AI voice and silence) that are common in scam operations, but the single voicemail did not contain explicit scam claims or requests. The unusual nature of the call and automated origin warrant treating it with caution and blocking it. If you have additional information about 03 9003 3520, report it to help establish a clearer picture.
Why did the voicemail from 03 9003 3520 just contain silence after the AI message?
Silence after an AI message on robocalls often indicates that the calling system is waiting for input (like pressing a number) or that the dialler is low-quality or abandoned. The robocall to 0390033520 may have been testing your number's responsiveness, or it may have been a misfired attempt where the next stage of the call did not execute. Either way, it is not a legitimate business practice.
Can I block 03 9003 3520 on my phone?
Yes. Most Australian phones allow you to block numbers directly through your phone's settings or through your carrier. After blocking 0390033520, the number will go straight to voicemail or be rejected. If the robocall continues from 03 9003 3520 or similar numbers, contact your carrier (Telstra, Vodafone, etc.) to escalate the issue or request additional filtering.
What should I do if I receive more calls from 03 9003 3520 or similar robocalls?
Block each number immediately, do not answer or return calls, and report the robocall to the ACMA at acma.gov.au. If 0390033520 or similar numbers continue to contact you despite blocking, you can lodge a formal complaint with the ACMA about harassment. Keep records of call dates and times to support your complaint.
