One contributor reports repeated silent calls from 08 6328 1831 (0863281831) and related numbers starting with 08 6328, checking if the line is active before hanging up.
Repeated Silent Calls from 08 6328 1831
A contributor has reported receiving silent calls from 08 6328 1831 (also written as 0863281831) as part of a pattern of daily harassment from multiple numbers all beginning with 08 6328. The caller remains silent for a few seconds after connection, then disconnects without speaking. This behaviour is characteristic of number-checking scams, where callers verify that a phone line is active before selling that information to other scammers or launching targeted attacks.
What makes 0863281831 particularly concerning is that it forms part of a larger cluster of similar numbers. The contributor notes that calls are coming from different numbers within the 08 6328 range every day, suggesting a coordinated operation rather than isolated nuisance calls. This pattern indicates the contributor's number has likely been added to a "live numbers" list used by multiple callers.
What Callers from 08 6328 1831 Do
When the contributor answered calls from 08 6328 1831, the caller said nothing and remained silent for a brief moment before ending the call. No attempt was made to deliver a sales pitch, collect information, or engage in conversation. This silent-then-hang-up pattern is a deliberate tactic used to confirm that a number is actively monitored, making it a valuable target for future scams.
The repeated nature of calls from numbers in the 08 6328 series suggests the caller is systematically working through a list. Each call from a different number in the same prefix may be an attempt to bypass blocking - if the contributor blocks 08 6328 1831, the next call comes from 08 6328 (different final digits), forcing the recipient to block multiple numbers.
Report Timing and Pattern
The contributor reported this issue on 13 October 2026 after experiencing multiple calls over an unspecified period. The pattern of daily calls from different numbers within the 08 6328 range indicates an ongoing campaign rather than a one-off call. The frequency and deliberate use of different numbers suggest this is an active nuisance operation targeting Western Australian numbers through Symbio Networks.
What to Do If You Receive a Call from 08 6328 1831
If 08 6328 1831 or related numbers starting with 08 6328 call you:
- Do not: Answer if you don't recognise the number, return any missed calls, or engage with callers who remain silent
- Do: Let calls go to voicemail, block each new number as it appears, and use your phone's native call-blocking features to filter calls from the 08 6328 prefix if your phone supports prefix-based blocking
- Do: Report the numbers to your phone provider - Symbio Networks may be able to investigate usage of their allocated numbers
Silent calls that check if a line is active are often the first stage in a scam pipeline. Once your number is confirmed as active, it may be sold to other scammers or used for future phishing attempts. Blocking the numbers stops them from gathering confirmation, but the underlying issue is that your number is already on a target list.
How to Report 08 6328 1831
Silent and nuisance calls can be reported to the Australian Communications and Media Authority (ACMA), which investigates complaints about unwanted calls and can take action against providers or carriers facilitating the calls.
- Report to ACMA: Visit acma.gov.au and use their complaint form to report silent calls from 08 6328 1831 and related numbers. Provide details of the dates, times, and numbers involved.
- Register with Do Not Call: Add your number to the Do Not Call Register at donotcall.gov.au. While this won't stop scammers, it helps ACMA identify illegal calling campaigns.
- Report on Reverseau: If you receive calls from 08 6328 1831 or other numbers in the 08 6328 range, contribute your experience on Reverseau. Community reports help identify broader calling patterns and alert other Australians to active campaigns.
- Contact your provider: Inform Symbio Networks that their allocated numbers (starting with 08 6328) are being used for silent nuisance calls. They may be able to suspend service or investigate the account.
Understanding the 08 6328 Cluster
The contributor's observation that multiple numbers all beginning with 08 6328 are being used is important context. This suggests the numbers are allocated to the same account or operation. When a scammer uses multiple numbers from the same exchange (08 6328), it often indicates they have access to a block of numbers or are using a VoIP service that assigns them sequentially. Reporting the pattern to ACMA and your provider is more effective than blocking individual numbers, as it flags the entire block as problematic.

Why would someone call and stay silent when I answer 08 6328 1831?
Silent calls from 08 6328 1831 are typically used to verify that your phone number is active and monitored.

Should I answer calls from 08 6328 1831 to find out who's calling?
No. Answering the call from 08 6328 1831 confirms that your number is active and monitored, which is exactly what the caller wants. This makes your number more attractive for future scams. The contributor who received silent calls from 0863281831 and related numbers found that answering did not result in any useful information - the caller simply remained silent and hung up. Let the call go to voicemail instead.
What does the 08 area code for 0863281831 mean?
08 is the area code for Western Australia. The contributor's report indicates that 08 6328 1831 (0863281831) is allocated to Symbio Networks Pty Ltd as a local service number in Western Australia. However, the fact that it is a legitimate-looking WA number does not mean the caller is legitimate - scammers frequently use spoofed or legitimately allocated numbers to appear genuine. The contributor noted that multiple different numbers in the 08 6328 range were being used, suggesting a coordinated operation using the same number block.
If I block 08 6328 1831, will the calls stop?
Blocking 0863281831 may help temporarily, but the contributor reported that calls continued to come from different numbers all starting with 08 6328 every day. Blocking individual numbers in the 08 6328 series is not a long-term solution because the scammer uses multiple numbers from the same prefix. If your phone supports prefix-based blocking, you may be able to block all calls starting with 08 6328. However, the most effective approach is to report the entire number block to ACMA and your phone provider.
Should I contact Symbio Networks about 08 6328 1831?
Yes. Since 08 6328 1831 (0863281831) is allocated to Symbio Networks Pty Ltd, contacting them to report the number is worthwhile. Provide details of the silent calls and the pattern of repeated calls from numbers in the 08 6328 range. Symbio Networks may be able to investigate whether the account holder is authorised to use the numbers for this purpose and take action to suspend service if the numbers are being misused.

08 6328 1831 (with spaces) and 0863281831 (without spaces) are the same phone number - just formatted differently. The spaced version is easier to read and is commonly used when displaying numbers to people. The non-spaced version is used for database lookups and technical systems.
