Silent Call Reports for 04 8398 1013

Three contributors have reported activity from 04 8398 1013 (also written as 0483981013), all involving silent or unanswered calls without voicemail content. The pattern suggests automated dialling behaviour rather than a genuine caller attempting to reach the recipient. One contributor described the calls as "giving off scammy vibes," while another noted the voicemail was left but contained only silence.

This Optus mobile number has been flagged for suspicious calling patterns typical of callback scams or test dialling used by threat actors to verify active numbers for later exploitation.

What Reports Indicate About 04 8398 1013

Contributors describe the behaviour as follows: One person received a missed call from 0483981013 with no message left. Another was contacted via voicemail, but when they checked the message, only silence played back. A third contributor answered the call from 04 8398 1013 but the caller hung up without speaking.

This silent calling pattern is consistent with callback scams, where automated systems dial numbers to identify active lines. When victims call back out of curiosity or concern, they may be connected to scammers operating investment schemes, tax impersonation, or other fraud. The fact that no message is left suggests the caller's goal is not to communicate directly, but to trigger a return call.

Report Patterns and Timing

The three reports span four days in late December 2025 and early January 2026, with calls occurring during standard business hours (9:06 AM and 10:55 AM). This timing is consistent with robocall or automated dialling campaigns that operate during peak contact windows.

All reports came through different channels: a missed call with no voicemail, a silent voicemail message, and a call the recipient answered (resulting in immediate hangup). The lack of message content across all three reports strongly suggests the same automated system or campaign testing the number's validity.

What to Do If You Receive a Call from 04 8398 1013

If 04 8398 1013 calls you:

• Do not: Return the call, answer if it keeps ringing, or engage if they do speak
• Do: Let calls go to voicemail, block the number immediately, and consider registering with the Do Not Call Register
• If you answered: Hang up without providing any information or confirming your name
• Do not: Press any numbers in response to recorded messages asking you to confirm you are home, press 1 to speak to someone, or any other prompt

Silent or callback scam calls often aim to identify active phone numbers for targeted fraud campaigns. Do not return the call under any circumstances, as you may be connected to organised scammers.
