Silent Call Reports for 04 8392 3599
Three contributors have reported unwanted contact from 04 8392 3599 (also written as 0483923599), a mobile number allocated to Optus. The most distinctive pattern involves silence on the line when calls are answered. One contributor specifically noted the caller as "a pest on the line, just hangs there in silence," indicating the number is actively being dialled rather than auto-generated mistakes.
The repeating behaviour across multiple reports suggests deliberate contact. Contributors report that 0483923599 rings persistently but never leaves a voicemail, making it impossible to determine the caller's identity or intent from a message. This silent-call tactic is often associated with callback scams or number verification, where the caller is testing whether a number is active.
Call Patterns from 04 8392 3599
All three reports to Reverseau came from answered or missed calls, with no SMS contact reported. The calls span across late November and early December 2025, showing ongoing activity. One contributor reported that 04 8392 3599 "keeps ringing but never leaves a message," indicating repeated attempts over time rather than a one-off misdial.
The lack of voicemail despite multiple contact attempts is a red flag. Legitimate callers typically leave a message explaining their purpose. The silent-call tactic used with 0483923599 is particularly concerning because it provides no way for the recipient to understand or address the reason for contact.
What to Do If You Receive a Call from 04 8392 3599
If 04 8392 3599 calls you:
- Do not: Answer if the caller ID is unknown, return the call, or provide any information if you do answer and hear silence
- Do: Let the call go to voicemail if possible, block the number immediately if calls repeat, and do not engage if silence persists on the line
- Callback risk: If you call back an unfamiliar number that called you silently, you may incur costs or enable scammers to confirm your number is active
Silent calls from 04 8392 3599 should be treated as potentially malicious. Hang up immediately if you answer to silence, do not stay on the line waiting for a response, and do not attempt to reach the number back.
