One contributor noted that after answering a call from 03 7057 7071, they heard silence followed by a pre-recorded goodbye, then attempted to call back to identify the caller but received the Optus service message. Another report describes receiving an automated voicemail from this number flagged as robocall spam. The deliberate disconnect between the calling number and its actual service status indicates possible number spoofing.
Report Patterns and Timing
The three reports for 03 7057 7071 span late January through early February, with reports arriving via missed calls, answered calls, and voicemail. Two contributors explicitly identified robocall tactics. One report remains categorised as uncertain after a missed call was flagged as scam by the contributor's device. The consistency of robocall characteristics across multiple reports suggests this is not accidental caller behaviour but rather a pattern of automated dialling activity.
What to Do If You Receive a Call from 03 7057 7071
If 03 7057 7071 calls you:
- Do not: Answer if the number is unknown, engage with any automated message, or attempt to call back

WRITE A REVIEWFrequently Asked Questions
Why do calls from 03 7057 7071 disconnect with silence?
Robocalls often use silence as a filtering tactic to identify active phone numbers. When you answer, the robocall system records that your number is active, which can lead to more frequent contact. Contributors reporting 03 7057 7071 describe this exact pattern: silence followed by a recorded message or disconnect. The number may also be spoofed, meaning the caller is using 0370577071 as a false identity rather than a legitimate service number.
What does it mean when 03 7057 7071 says 'not in service' when you call back?
When you call back 03 7057 7071 and receive an Optus message that the number is not in service, this indicates the number may be spoofed or inactive between outbound calls. Robocall operations often use numbers that appear legitimate but cannot be reached, preventing call recipients from verifying the caller's identity. This is exactly what one contributor experienced with 0370577071, confirming the spoofing pattern.
Should I answer if I see 03 7057 7071 calling?
No. Contributors who answered calls from 03 7057 7071 reported only silence or automated messages, gaining no useful information. If you recognise the number from these reports, let it go to voicemail and block 0370577071 immediately. Do not attempt to engage with the call or call back the number.
Is 03 7057 7071 a legitimate Victoria business number?
The number is registered as a local service number in Victoria allocated to Symbio Networks Pty Ltd. However, the robocall reports from 03 7057 7071 suggest the number is being spoofed or misused. The Optus 'not in service' response when contributors attempted callbacks indicates the number is not functioning as a normal service line. If you believe this is your business number being spoofed, contact Symbio Networks directly using verified contact details from their official website.
Why are there so many robocalls from similar-looking numbers?
Robocall operators often spoof local numbers because people are more likely to answer calls from familiar area codes like 03 7057 XXXX (Victoria area). The number 0370577071 follows standard Australian phone patterns, making it appear trustworthy. Contributors report that the silence-then-message pattern is a common robocall filtering technique used across many numbers to identify active lines for future targeting.
What should I do if I keep getting calls from 03 7057 7071?
First, block 0370577071 in your phone settings. Second, report the number to ACMA at acma.gov.au if calls are frequent or harassing. Third, avoid answering calls from numbers you don't recognise. Fourth, do not attempt callbacks to 03 7057 7071. If the calls persist after blocking, contact your phone provider (in this case, potentially Optus or another provider) to request network-level filtering. Document each call with date and time for your report.
