Silent Call Reports for 03 9003 9391

Three contributors have reported suspicious behaviour from 03 9003 9391 (also written as 0390039391). The most recent report describes a silent call where the contributor answered but heard only silence on the line - no background noise, no greeting, no attempt to communicate. This pattern is characteristic of automated systems testing whether a number is active and monitored.

Two additional reports about 0390039391 describe calls that either dropped immediately upon connection or went unanswered with no voicemail left behind. The absence of any voicemail message is notable, as legitimate callers almost always leave a brief explanation of their purpose when unable to reach someone.

Call Patterns from 03 9003 9391

All three reports involving 03 9003 9391 occurred within a single month (late February to late March 2026). One contributor received the silent call during early morning hours (1:01 AM), while another answered a dropped call around mid-morning (11:09 AM). This varied timing suggests the calls may be part of automated dialling campaigns rather than attempts by a specific person trying to reach you.

The pattern of silent calls followed by dropped connections is consistent with robocall or callback-request scam systems. These systems dial large numbers of contacts to verify active phone lines, then either remain silent if someone answers, or disconnect and attempt follow-up contact later when the line is more likely to be monitored.

What to Do If You Receive a Call from 03 9003 9391

If 0390039391 calls you:

• Do not: Answer the call if you don't recognise the number, return a missed call to this number, or provide any personal information if you do answer
• Do: Let unknown calls go to voicemail, block the number on your phone immediately after receiving it, and note the date and time if you answer and experience silence or a dropped connection
• Know the risk: Silent calls and immediate disconnections are often used by scammers to identify active phone numbers before launching follow-up scams. Once they confirm your line is active, they may call back impersonating utilities, banks, or government agencies

Silent Calls and Callback Scams

The silent call tactic serves a specific purpose in scam operations. When you answer 03 9003 9391 and encounter silence, automated systems are recording that your number reached a real person. This data is then sold or used internally to refine targeting for more intensive scam campaigns. Dropped calls may be part of the same verification process or could indicate callback-request fraud, where the goal is to have you return the call to an expensive premium line.

Contributors who receive repeated calls from 0390039391 or similar silent numbers should remain cautious about any subsequent contact, even if it appears to come from a known organisation. Scammers frequently follow silent calls with impersonation attempts targeting banks, utilities, or tax authorities.
