Silent Call Reports for 02 8004 3611
Two contributors have reported receiving calls from 02 8004 3611 (also written as 0280043611) where no message was left and the caller did not engage. Both reports describe a pattern of repeated contact with no voicemail, suggesting automated dialling or callback scam probing behaviour.
The number is allocated to Symbio Networks, a local service provider in NSW. While the allocation itself is legitimate, the calling pattern reported by contributors suggests the number may have been spoofed or misused for unwanted contact campaigns.
Call Pattern and Frequency
One contributor noted that 02 8004 3611 was part of a broader issue: "This and other numbers with 8004 are constantly ringing, leaving no messages either." This suggests the contributor may be experiencing repeated contact attempts from multiple numbers in the same range, which is typical of robocall or callback scam operations that test numbers for active status.
The second report from April 2026 describes a single missed call with no message, recorded as deleted without further investigation. Neither contributor returned the call, which is the correct response to unknown missed calls.

What does a silent call or callback scam from 02 8004 3611 mean?
Silent calls with no message from 02 8004 3611 (0280043611) are often robocalls or callback scams testing whether your number is active and monitored. If you return the call, you may be connected to a scammer or charged a premium rate. The correct response is to not return the call and block the number.
Should I answer or return a call from 0280043611?
No. If 02 8004 3611 calls and leaves no message, do not return the call. This is a common callback scam tactic. Returning calls to unknown numbers can result in premium charges or connecting you to scammers posing as government agencies or utilities.
Why is 02 8004 3611 calling me if it's a legitimate Symbio Networks number?
While 0280043611 is allocated to Symbio Networks (a real NSW provider), the number may be spoofed by scammers or misused by third parties for robocalling campaigns.

On most Australian phones, you can block 02 8004 3611 by opening the call log, selecting the number 0280043611, and choosing 'Block' or 'Add to Reject List.' For older landlines, contact your provider about blocking options. Registering at donotcall.gov.au also helps reduce unwanted calls.
What should I do if I keep getting calls from 02 8004 3611 or similar 8004 numbers?
