Callback Lure Reports for 03 9996 8066

Two contributors have flagged 03 9996 8066 (also written as 0399968066) for suspicious calling behaviour typical of callback scams. The pattern involves repeated calls that terminate without voicemail, designed to prompt recipients to return the call. One contributor explicitly noted the calling strategy as a classic nuisance tactic aimed at enticing callback responses.

Both reports about 0399968066 indicate behaviour consistent with callback lure schemes, where the goal is to generate outbound calls that may trigger unexpected charges or lead to unwanted interaction with scammers or spammers.

What Callers from 03 9996 8066 Do

The first report describes multiple missed calls from 03 9996 8066 with no message left, followed by a hang-up when the line connected. The contributor noted this repetitive pattern as a deliberate tactic to provoke a callback.

The second report documents an automated greeting left on voicemail, asking the recipient to state their name. This type of recorded message is often used to verify active phone numbers or collect voice samples for social engineering purposes.

Both incidents were traced to Netsip (Netsip Pty Ltd), a Victoria-based provider. One contributor reported receiving the majority of their spam calls from Netsip-allocated numbers, suggesting systemic patterns with this provider's infrastructure.

Report Patterns and Timing

Reports span early August through late August 2026. The first callback lure incident involved repeated call attempts before disconnection, while the automated voicemail greeting arrived via a single contact attempt. Neither report specified the exact time of day, though both describe typical daytime or evening calling windows.

The clustering of reports within a four-week period, combined with mention of repeated daily calls from Netsip numbers, suggests ongoing activity from this provider's numbering space rather than isolated incidents.
