Silent Calls and Robocalls from 04 8583 7891

Four contributors have reported suspicious activity from 04 8583 7891 (also written as 0485837891), with a clear pattern of silent calls and automated robocalls. Two separate reports describe callers who say nothing after answering, while another contributor noted the number keeps ringing and hanging up with the last three digits changing between calls - a hallmark of robocall spoofing tactics.

The 0485837891 number is registered as a mobile service through Pivotel satellite, though contributors suspect the calls may be spoofed or originating from different sources given the number variation pattern. One report mentions similar calls from other numbers in the 837 range, suggesting a coordinated campaign rather than isolated nuisance calls.

What Callers from 04 8583 7891 Do

When answered, calls from 04 8583 7891 typically involve silence. One contributor reported hearing "g'day" twice followed by complete silence before the caller hung up. Another described the same pattern: the number calls, but the person on the line says nothing before disconnecting.

Beyond silent calls, one contributor reported that 0485837891 was used in a solar rebate scam attempt. The variation in tactics - from silent calls to scam pitches - suggests multiple uses of this number or related numbers in the 837 range by different actors. The robocall aspect is particularly concerning, as contributors noted the last three digits changing on repeated attempts, indicating automated systems cycling through number variations.

Report Patterns and Activity

The four reports span from late October to mid-November 2025, with calls occurring at various times including early morning hours (03:34) and mid-morning (10:54). Three reports came from answered calls, one from a missed call. The contributor who experienced repeated robocalls noted the pattern of ringing and hanging up, suggesting the system may be testing active numbers rather than attempting genuine contact.

One contributor observed that similar calls came from other numbers in the 837 range, indicating a larger network of problematic numbers operating simultaneously. This pattern is typical of automated scam or nuisance call operations that use number spoofing to increase call volume and evade blocking.

What to Do If You Receive a Call from 04 8583 7891

If 04 8583 7891 calls you:

• Do not: Answer if you don't recognise the number, engage with any pitch (especially solar or energy rebates), or provide any personal information
• Do: Let it go to voicemail, block the number immediately, and report it to your phone provider
• If you hear silence: Hang up immediately - this is a common robocall verification tactic to confirm your number is active
• If the pitch is solar rebates: Remember legitimate government rebate programs never cold-call and always verify through official channels like the relevant state energy regulator

Do not call the number back. Robocalls and silent call operations often use callback requests as part of their revenue model, either charging premium rates or using the return call to verify your number for further targeting.
