Robocall and Voice Recording Scam Reports for 03 8658 7309
Four contributors have flagged 03 8658 7309 (also written as 0386587309) for suspicious activity involving disconnected numbers and potential spoofing. One contributor received an automated call from 03 8658 7309 featuring an AI agent claiming to conduct cost-of-living research. When the contributor attempted to return the call to 0386587309, the line was no longer in service, raising concerns about voice recording harvesting or identity fraud.
The pattern across reports suggests this number may be used as a spoofed caller ID rather than a legitimate contact line. Multiple contributors who received missed calls from 03 8658 7309 discovered the number is not in service when attempting callbacks, which is a common indicator of spoofing tactics used in scam operations.
What Callers from 03 8658 7309 Claim
The one contributor who answered a call from 0386587309 reported an AI voice agent introducing itself as conducting cost-of-living research. The robocall did not appear to be a genuine survey operation, particularly given the number's immediate unavailability after the call. This pattern of research-themed pretexts combined with voice harvesting suspicions suggests the call was designed to record voice samples for potential fraud purposes, such as voice cloning or identity theft.
Contributors attempting callbacks to 03 8658 7309 consistently reached a "not in service" message, confirming the number cannot be reached through normal telephone channels. This behaviour is characteristic of spoofed numbers, where scammers use temporary or invalid caller IDs that appear on recipient phones but do not function as actual contact lines.
Call Patterns and Timing
Reports of calls from 03 8658 7309 span from late October 2025 through early January 2026, indicating ongoing activity over a three-month period. One call was reported at 7:30 PM in early November. The most recent report from January 2026 involved the AI robocall research pretence, while earlier reports from October and November recorded missed calls where 0386587309 appeared as the caller ID but disconnected immediately.
The Victoria-based allocation (Symbio Networks service) combined with the not-in-service status suggests either a compromised local number or spoofed caller ID masking the actual originating location of the calls.

WRITE A REVIEWFrequently Asked Questions
Why does 03 8658 7309 disconnect when I try to call back?
Multiple contributors report that 0386587309 is not in service when called back, which is a key indicator of spoofing. Scammers often use temporary caller IDs or spoofed numbers that appear on your phone but are not functional lines. This allows them to make outbound calls while remaining untraceable. Never attempt repeated callbacks to 03 8658 7309, as this confirms your number is active to scammers.
Is the cost-of-living research call from 03 8658 7309 legitimate?
No. The contributor who answered the call from 03 8658 7309 (0386587309) reported an AI voice agent, not a human researcher. Legitimate government and university surveys do not use AI robocalls and do not disconnect immediately after. The combination of an automated voice, generic research pretence, and the immediate unavailability of the number strongly indicates a voice harvesting scam.
What is voice recording harvesting, and why would 0386587309 do this?
Voice harvesting involves recording a target's voice responses to build samples that can be used for voice cloning, identity fraud, or deepfake audio. By asking you to respond to a survey question from 03 8658 7309, scammers capture your voice pattern. This can later be used to impersonate you in banking or legal transactions. Do not engage with any voice prompts from this number.
How common are spoofed numbers like 03 8658 7309?
Spoofed caller IDs are a widespread scam tactic in Australia. Scammers use software to mask their real number and display a legitimate-looking Victorian number like 03 8658 7309 instead. The fact that multiple contributors received calls from 0386587309 but found it not in service confirms this is a spoofed number, not a real business line.
Should I report 03 8658 7309 to my phone provider?
Yes. After blocking 03 8658 7309 on your phone, contact your provider (in this case, Symbio Networks if you are a customer) and report the spoofed number. You should also report it to ACMA at acma.gov.au so they can investigate the spoofing activity. The more reports ACMA receives about 0386587309, the more likely they are to take action against the scammer.
What should I do if I already answered and gave information to 03 8658 7309?
If you provided voice responses or personal information to a caller from 03 8658 7309 (0386587309), monitor your bank and credit accounts closely for suspicious activity. Change passwords on financial and government accounts (including myGov). Report the call to Scamwatch (scamwatch.gov.au) and ACMA immediately. If voice was recorded, contact Services Australia and your bank to flag potential identity fraud risks.
