Silent Call Reports for 08 7534 5964
Three contributors have reported receiving repeated calls from 08 7534 5964 (also written as 0875345964), a South Australian local number allocated to Symbio Networks. Each report describes the same pattern: calls that arrive with no voicemail message left behind, and callers who do not respond when contacted back.
The most recent report from January 2026 describes the calls as "super annoying," while an earlier contributor noted receiving "a few calls" from 0875345964 with persistence over time. A third report from December 2025 similarly mentions multiple calls from this number without any message left on voicemail.
Call Patterns and Frequency
All three reports of 08 7534 5964 involve missed calls rather than answered conversations, making it difficult for contributors to identify who is calling. The pattern across the reports suggests repeated dialling behaviour - at least two contributors explicitly mention receiving multiple calls from this number over time.
These silent calls typically fall into one of two categories: either accidental misdials that reach the wrong number repeatedly, or deliberate callback scams where callers hope recipients will return the call to an expensive premium service. The fact that 0875345964 has generated three separate reports within six weeks suggests this is not a one-off occurrence.
What to Do If You Receive a Call from 08 7534 5964
If 08 7534 5964 continues to call you:
- Do not: Return the call to this number, as silent calls often lead to expensive premium-rate services
- Do: Block the number on your phone to prevent further calls
- Do: Let calls go to voicemail - if it is a legitimate caller, they will leave a message
- Do: Check your phone settings to filter calls from unknown numbers
If you answer and hear silence or a dial tone, hang up immediately. Do not press any numbers or stay on the line, as this can trigger additional calls or charges.

WRITE A REVIEWFrequently Asked Questions
Why do I keep getting silent calls from 08 7534 5964?
Silent calls from 08 7534 5964 can occur for several reasons: the caller may be using an automated dialling system that connects to a live operator only when someone answers, or it could be a callback scam hoping you'll return the call. Three contributors have reported repeated silent calls from 0875345964, all with no voicemail message, which is typical of these patterns. If it continues, block the number.
Is 08 7534 5964 a scam?
Three reports of 08 7534 5964 describe silent calls with no messages, making it impossible to confirm intent from the reports alone. The silent call pattern is consistent with either misdials or callback scams. What's clear from contributor feedback is that 0875345964 repeatedly calls without leaving a message, which is a red flag. Block it and report any resumed calls.
What should I do if I accidentally call 08 7534 5964 back?
If you call 0875345964 back out of curiosity, hang up immediately if you reach an automated system or hear silence. Do not press any keypad numbers or stay on the line. Silent call numbers sometimes connect to premium-rate services designed to charge your phone account. If you've called back and incurred charges, contact your phone provider to dispute them.
Can I block 08 7534 5964 on my mobile?
Yes. Most Australian mobile phones allow you to block incoming calls from specific numbers. Go to your Phone app, find 08 7534 5964 in your call history or contacts, and select "Block" or "Add to Blocked List." Once 0875345964 is blocked, calls from that number will go straight to voicemail or be rejected silently.
Who is the provider behind 08 7534 5964?
08 7534 5964 is allocated to Symbio Networks Pty Ltd as a South Australian local service number. However, allocation data does not identify who is actually making calls from 0875345964. The three contributors reporting this number have not identified a caller, only that calls come through repeatedly with no message. Reverseau's community reports indicate this pattern is suspicious.
Should I report 08 7534 5964 to ACMA?
Yes. If 08 7534 5964 calls you repeatedly without leaving a message, report it to ACMA at acma.gov.au. ACMA investigates patterns of silent and nuisance calls, and multiple reports about 0875345964 strengthen the evidence. You can also report the number here on Reverseau to warn other South Australian residents about this pattern.
