Silent Call Reports for 08 8166 5871
Seven contributors have reported activity from 08 8166 5871 (also written as 0881665871), with a consistent pattern of silent calls and suspicious missed calls. Two separate reports specifically mention silent calls where the caller hung up immediately after the recipient answered or call screening activated. The number is registered as a local service in South Australia through NetSIP Pty Ltd, yet multiple contributors encountered unexpected behaviour when attempting to verify the number.
What stands out across reports about 0881665871 is the persistent pattern of calling without leaving voicemail messages, coupled with the silence when calls are answered. One contributor who called back to investigate found that Optus reported the number as disconnected, raising questions about the legitimacy of the calling source.

Contributors who answered calls from 08 8166 5871 encountered complete silence on the line. One described it as "kinda dodgy," while another reported the line going silent when they picked up. Neither caller attempted any communication or left any voicemail message.
The calling behaviour suggests automated activity rather than a person attempting genuine contact. Several contributors received multiple calls from 0881665871 with no message left behind, described by one as a "ghosting move." One contributor reported using call screening, after which the caller hung up immediately when the call began to record, suggesting awareness of screening systems.
Call Patterns and Frequency
The reports span from September to November 2025, with most activity concentrated in early September. One contributor specifically noted that 08 8166 5871 was calling "suspiciously often," and several described missing multiple calls without voicemail follow-up. The mix of answered and missed calls suggests persistent attempt patterns rather than accidental dialling.
Contributors used phone features to protect themselves, with at least one using call screening that triggered the immediate hang-up, and others blocking the number after recognising the suspicious pattern. A phone alert system flagged the number as suspicious to at least one recipient before they even answered.
What to Do If You Receive a Call from 08 8166 5871
If 08 8166 5871 calls you:
- Do not: Answer if you don't recognise the number; return the call to verify legitimacy; engage with any message if one is left
- Do: Let it go to voicemail, enable call screening if your phone supports it, block the number if calls persist, and report it to your phone provider
- For callback verification: Do not call the number back directly; instead, contact your service provider (such as Optus) via their official customer service number to verify whether the number is legitimate or disconnected
Silent calls combined with disconnected number status suggest this may be an automated system that has failed or is being used to test active phone numbers. Do not return the call or provide any information if you accidentally answer.

WRITE A REVIEWFrequently Asked Questions
Why did I get a silent call from 08 8166 5871?
Multiple contributors to Reverseau received silent calls from 08 8166 5871 (0881665871) where the caller hung up immediately or said nothing when the call was answered. This pattern is typical of automated calling systems testing whether numbers are active, or potentially campaigns using silent calls to harvest active phone numbers for later scam attempts. One contributor's attempt to call back found the number reported as disconnected by Optus, which suggests the calling source may not be a legitimate business.
Should I answer if 08 8166 5871 calls again?
No. Contributors who answered calls from 08 8166 5871 experienced only silence, wasting their time. Let the call go to voicemail instead. If you have call screening enabled on your phone, use it - one contributor reported that the caller hung up immediately when their phone's recording system activated. The safest approach is to block 0881665871 after the first silent call.
Is 08 8166 5871 a scam number?
Based on community reports for 08 8166 5871, the behaviour is consistent with either spam automation or number-testing activity rather than a traditional scam. Silent calls combined with no voicemail messages suggest the caller isn't attempting actual contact. However, silent calls are sometimes used as preliminary steps before scam attempts. One contributor who called back was told by Optus that 0881665871 was disconnected, which is suspicious. It's safest to treat it as nuisance/spam and block it.
Why does Optus say 08 8166 5871 is disconnected?
One contributor called back 08 8166 5871 to verify the caller and was told by Optus that the number is disconnected. This is unusual given that the number is registered as a local service in South Australia and is clearly active enough to make outgoing calls. This contradiction raises concerns about the legitimacy of the calling source and may indicate the number is spoofed, reassigned, or being misused. You should not call 0881665871 back yourself to verify - instead, contact Optus directly through their official customer service number.
How often is 08 8166 5871 calling people?
At least one contributor to Reverseau reported that 08 8166 5871 (0881665871) was calling "suspiciously often," though specific frequencies weren't detailed in reports. Most reports show missed calls with no voicemail left behind, suggesting multiple attempts to reach numbers. The reports span from September to November 2025, indicating the number has been actively calling over several weeks.
What should I do if I already answered a call from 08 8166 5871?
If you already answered 08 8166 5871 and heard silence, you didn't provide any information, so there's minimal risk. The main step is to block the number going forward to prevent future calls. If you accidentally provided any personal information (name, date of birth, bank details), monitor your accounts for suspicious activity and consider reporting to relevant authorities. Block 0881665871 immediately and report it to ACMA at acma.gov.au. You can also file a report on Reverseau to help other Australians recognise this calling pattern.
