Community reports for 03 4059 6545 (0340596545): Two contributors report disconnected/out-of-service responses when attempting to verify the number after receiving calls.
Suspicious Activity Reports for 03 4059 6545
Two contributors have flagged the number 03 4059 6545 (also written as 0340596545) for suspicious behaviour. Both reports involve attempts to call back after receiving incoming calls, with unusual responses suggesting the number may not be a legitimate active service.
The allocation data shows 03 4059 6545 is registered as a local service through Symbio Networks Pty Ltd in Victoria. However, contributor experiences suggest the number may be spoofed or inactive, which is a common tactic in scam operations.
What Contributors Experienced with 03 4059 6545
One contributor received a missed call from 03 4059 6545 with no voicemail left. When they attempted to call back, an Optus automated message indicated the number was disconnected. This pattern - incoming call followed by a "disconnected" response on callback - is often associated with caller ID spoofing, where scammers use fake numbers to initiate contact.
A second report described calling back 0340596545 and receiving an automated voice stating "number not in service." This response, combined with the earlier missed call, suggests the incoming call did not originate from an active service under that number.
Report Patterns and Timing
Both reports came from missed or answered calls rather than voicemail messages. The reports were submitted in early November 2025, spanning a week apart. Neither contributor provided detail about the time of day or frequency of calls, making it difficult to identify broader calling patterns.

WRITE A REVIEWFrequently Asked Questions
What does it mean when a callback to 03 4059 6545 says 'disconnected'?
When you call back 03 4059 6545 and receive a "disconnected" or "not in service" message, it typically indicates the incoming call was spoofed - meaning scammers used a fake number to appear on your caller ID. The number may not be active or may be registered to a different service. This is a red flag and you should not attempt further contact.
Why would someone call from 0340596545 if the number isn't in service?
Caller ID spoofing allows scammers to display any phone number on your screen, including 0340596545, even though the call didn't originate from that number. They use this tactic to appear legitimate or to make their calls harder to trace. If you call back and reach a disconnected message, this confirms spoofing.
Is 03 4059 6545 a real Symbio Networks number?
The number 03 4059 6545 is allocated to Symbio Networks Pty Ltd in Victoria, but that does not guarantee it's legitimate. Scammers often spoof allocated numbers to appear credible. The fact that contributors received "disconnected" responses when calling back suggests the incoming call was not genuinely from this allocation.
Should I call back a missed call from 03 4059 6545?
No - if you receive a missed call from 03 4059 6545 with no voicemail, do not call back. If the caller had a legitimate reason to reach you, they would leave a message. Calling back may confirm your number is active to scammers or incur costs. Instead, block the number and report it to ACMA.
How can I report calls from 0340596545?
You can report calls from 0340596545 to ACMA at acma.gov.au or phone 1300 850 115. If you suspect the call was a scam attempt, also report to Scamwatch at scamwatch.gov.au. Community reports on Reverseau also help other Australians identify this number.
What should I do if 03 4059 6545 keeps calling?
Block the number immediately in your phone's call settings. Each time you receive a call from 03 4059 6545, note the date and time, and whether a message was left. Report repeated calls to ACMA, as patterns of persistent calling from spoofed or inactive numbers may indicate organised scam activity.
