Suspicious Activity Reported for 03 8747 3377
A contributor has flagged 03 8747 3377 (also written as 0387473377) as part of a pattern of suspicious calling activity. The report indicates multiple calls arriving weekly, originating from different Sunbury-based numbers, with blank voicemail messages left each time. This coordinated approach from varying numbers suggests potential automated or organised calling behaviour rather than isolated misdials.
The allocated service type for 0387473377 is a local service provider based in Victoria, registered to Symbio Networks Pty Ltd. The use of multiple Sunbury numbers in conjunction with silent voicemails is a tactic sometimes employed to bypass call filtering systems or to probe active phone numbers before escalating contact attempts.
Call Pattern and Behaviour
The contributor experiencing calls from 03 8747 3377 reports receiving several calls per week, consistent enough to warrant attention but not yet at harassment levels. The defining characteristic is the silence on voicemail - no message content, no callback request, no indication of legitimate business purpose. This contrasts sharply with genuine service providers, who typically leave identifiable messages.
The use of multiple Sunbury phone numbers rather than a single repeating number suggests either a deliberate strategy to circumvent call-blocking or a sign of robocall network activity where different numbers are used to increase answer rates.
What to Do If You Receive Calls from 03 8747 3377
If 0387473377 or related Sunbury numbers continue to call you:
- Do not: Return any missed calls, as this confirms your number is active and monitored
- Do: Block the number immediately in your phone settings
- Do: Let future calls go to voicemail without answering
- Do: Note the frequency and dates if calls persist, as this documentation strengthens reports
- Do: If the pattern escalates to multiple calls daily, escalate your report to ACMA
Blank voicemail messages combined with repeated calls from different numbers is a red flag for either robocall testing or preparation for a larger scam attempt. Engagement (answering or returning the call) is unlikely to stop the behaviour and may increase contact frequency.

WRITE A REVIEWFrequently Asked Questions
Why are calls from 03 8747 3377 leaving blank voicemails?
Blank voicemail messages are often used to verify that a phone number is active without revealing the caller's identity or intent. This is a common tactic in robocall campaigns where different numbers (including 03 8747 3377) are used to test lists of valid phone numbers before launching a larger scam or spam operation. The silence indicates intentional non-communication rather than a technical fault.
Should I call back 0387473377 to find out who's calling?
No. Calling back 0387473377 or any related Sunbury number confirms your phone is monitored and actively used, which can increase the frequency of future calls. This is exactly what blank voicemail callers want to establish. Let missed calls go to voicemail instead.
Why are multiple Sunbury numbers calling instead of one number?
The use of multiple numbers from 03 8747 3377's area code is a deliberate strategy. Callers using different numbers can bypass call-blocking software designed to block a single repeating number. Sunbury-based numbers give the impression of local calling, which increases answer rates compared to national or overseas numbers.
What should I do if calls from 03 8747 3377 escalate?
If the frequency of calls from 0387473377 increases significantly (moving from weekly to daily), or if calls start leaving actual messages with demands or offers, report the activity immediately to ACMA at acma.gov.au. Document dates, times, and any content from voicemails. This documentation is critical for investigations.
Is 03 8747 3377 a known scam number?
Based on current community reports, 03 8747 3377 (0387473377) is flagged as suspicious rather than a confirmed active scam. The blank voicemail pattern suggests probe calls or testing behaviour rather than a live scam operation. However, numbers used this way often precede scam attempts, so early blocking is prudent.
Can I block 03 8747 3377 and related Sunbury numbers on my phone?
Yes. Most Australian phones allow you to block individual numbers through settings. For 0387473377, add it to your blocked list. You may also want to enable 'Silence Unknown Callers' on iPhone or use Google Call Screen on Android. For ongoing nuisance from multiple Sunbury numbers, consider registering with the Do Not Call Register at donotcall.gov.au.
