Silent Call Reports for 04 2397 2866
Two contributors have reported receiving silent calls from 04 2397 2866 (also written as 0423972866), a mobile number allocated to Optus Mobile. Both reports describe the same pattern: when the recipient answered, there was complete silence on the line with no response or hangup delay.
This behaviour is commonly associated with callback scams, where automated systems test whether a number is active and monitored. If you answer, the scammer's system flags your number as "live" for follow-up contact attempts, often from spoofed numbers impersonating government agencies, banks, or utilities.
What Contributors Experienced with 04 2397 2866
One contributor described the call from 0423972866 as "a silent split second call most likely a scam caller." The second report noted simply "dead silence when I answered." Both calls connected but produced no audible response, no breathing, and no background noise - consistent with an automated detection system rather than a human caller.
Silent calls from 04 2397 2866 hung up immediately after the recipient picked up, leaving no opportunity to interact with or identify the caller. Neither contributor heard any robotic voice, music, or mechanical sound that might indicate an answering machine or IVR system.
Why Silent Calls Happen
Silent calls from numbers like 04 2397 2866 serve as "ping" tests in the scam pipeline. By detecting that 0423972866 reaches an active, monitored line, the system marks your number for secondary scam attempts. These follow-up calls often impersonate the ATO, NBN, delivery services, or banks, armed with the knowledge that you answer your phone.
The Optus Mobile allocation of 04 2397 2866 does not guarantee the caller is legitimate, as mobile numbers are frequently spoofed or hijacked for scam campaigns.
