Robocall and Silent Call Reports for 03 7048 3073
Ten contributors have reported suspicious activity from 03 7048 3073 (also written as 0370483073), with a clear pattern of automated robocalls and silent calls that disconnect within seconds. The number is registered as a local Melbourne service through Symbio Networks in Victoria, yet multiple callers who attempted to call back reported the number as not in service, suggesting the calls are being spoofed.
Community reports indicate two distinct behaviours: robocalls with automated messages or pre-recorded content, and silent calls where the line connects briefly before the caller hangs up. One contributor reported receiving a call from someone claiming to be "Tez from Australian Research Centre," but noted the voice sounded automated. Another described an automated call where they couldn't catch what was being discussed. These patterns are consistent with scam infrastructure designed to test active numbers or harvest personal data.
What Callers from 03 7048 3073 Do
The behaviour from 0370483073 falls into two categories. Some calls are silent - the phone rings, and when answered, the caller immediately disconnects. One contributor described: "Rang and hung up, seems like a scam based on others' reports." Another noted: "Phone rang and caller hung up quickly."
Other calls from 03 7048 3073 are robocalls with pre-recorded or automated messaging. A contributor who answered reported: "Automated call, didn't catch what it was about, seems dodgy." The caller claiming to be from "Australian Research Centre" with a voice that "sounded automated" suggests these may be scripted calls rather than live conversations. No contributor reported being asked for personal information, payments, or specific claims about debts or services.
Call Patterns and Timing
Reports of 03 7048 3073 span from July 2024 through March 2026, with several clusters in mid-2025 and early 2026. Many calls went unanswered and left no voicemail. One contributor specifically noted being on the Do Not Call Register and still receiving a call from this number in July 2025. Others reported calls arriving at varying times, including early morning hours (around 5 AM and 7 AM based on timestamps).
The pattern of brief or hang-up calls is typical of scammers testing whether a number is active before deploying more targeted scams. The fact that multiple contributors report the number as "not in service" when called back strongly suggests the calls are spoofed - the scammers are masking their actual number with 0370483073 to appear local.
What to Do If You Receive a Call from 03 7048 3073
If 03 7048 3073 calls you:
- Do not: Answer if you don't recognise the number; return a call to this number; engage with any voicemail or recorded message
- Do: Let it go to voicemail; block the number immediately on your phone; report it as spam or scam if your phone allows; note the time and date for your records
- Do not: Press any buttons during a recorded message, as this may confirm your number is active and lead to more calls
- Do: Be aware that even if you call back and hear "number not in service," this doesn't mean your original call was a misdialled customer - it indicates a spoofed number
Report 03 7048 3073 to Australian Authorities
Community reports are valuable, but also lodge formal complaints with Australian government agencies:
- ACMA (Australian Communications and Media Authority): Report unwanted calls and robocalls at acma.gov.au. ACMA tracks patterns across the network and can take enforcement action against repeat offenders.
- Scamwatch: Report suspected scams at scamwatch.gov.au. Even if no money was lost, reports help authorities understand emerging scam tactics.
- Do Not Call Register: If you're registered and still received a call, file a complaint at donotcall.gov.au. Breach of the register is enforceable.
- Reverseau: Report this number directly on Reverseau to help other Australians identify and avoid 0370483073.
Why Scammers Use Silent Calls and Robocalls
Silent calls and robocalls from spoofed numbers like 03 7048 3073 serve several purposes for scammers. Silent calls confirm to scammers that your number is active and monitored by a real person, making your number more valuable for sale on underground markets or for follow-up scam campaigns. Robocalls with vague messaging or difficult-to-understand content avoid triggering immediate fraud detection while still testing your number's status. The use of a spoofed local Melbourne number increases the likelihood you'll answer, as local calls feel more trustworthy than unknown area codes.

WRITE A REVIEWFrequently Asked Questions
Is 03 7048 3073 a real number or spoofed?
Multiple contributors reported that when they called 0370483073 back, they received a "number not in service" message. This strongly indicates the number is spoofed - scammers are masking their actual identity by displaying 03 7048 3073 on your caller ID. The number appears registered to Symbio Networks in Victoria, but the incoming calls are fraudulent.
Why do they hang up immediately when I answer 03 7048 3073?
Silent calls from 0370483073 are designed to confirm your number is active and monitored. When you answer, the scammer's goal is achieved - they now know a real person uses this number. That information can be sold to other scammers or used for follow-up attack waves. Hanging up immediately keeps call duration (and cost) minimal.
Should I call back 03 7048 3073?
No. Do not call back 0370483073. Several contributors who did call back found the number was "not in service," wasting their time. More importantly, calling back a spoofed number won't reach the scammer anyway - it will reach an innocent person whose number has been hijacked. Block 03 7048 3073 and move on.
What is 'Australian Research Centre' mentioned in reports from 0370483073?
One contributor reported receiving a robocall from 03 7048 3073 where someone claiming to be "Tez from Australian Research Centre" had a voice that "sounded automated." This is likely a spoofed company name used to appear legitimate. No such verified organisation appears to be calling Australian numbers through this number. If you receive this claim from 0370483073, treat it as a scam.
I'm on the Do Not Call Register - why did 03 7048 3073 call me?
A contributor reported receiving a call from 0370483073 in July 2025 despite being registered on the Do Not Call Register. Scammers deliberately ignore the register, as they operate outside the law. Report this breach at donotcall.gov.au and file a separate scam report at acma.gov.au. Both breaches are enforceable against the original caller.
What should I do if 03 7048 3073 keeps calling me?
Block 0370483073 immediately using your phone's built-in block feature. Do not engage or answer. If calls persist after blocking, file a formal complaint with ACMA (acma.gov.au) documenting dates and times. Consider registering with the Do Not Call Register if not already listed (donotcall.gov.au). Each new call can be logged with police (police.vic.gov.au) as harassment if the pattern continues.
