Silent Calls and Spam from 03 9022 0403

Four contributors have reported unwanted contact from 03 9022 0403 (also written as 0390220403), a local service number registered to NetSIP Pty Ltd in Victoria. The reports paint a picture of mixed nuisance behaviour, ranging from hang-ups to automated calls requesting personal information. Unlike targeted scams with specific financial demands, this number appears associated with low-effort spam tactics designed to test numbers or harvest data.

The pattern from 0390220403 suggests multiple contact methods being tested on the same number, or potentially different campaigns cycling through the same line. One contributor describes a silent hang-up; another encountered an automated political survey; a third faced a health insurance market research call that pivoted toward collecting personal details.

What Callers from 03 9022 0403 Do

Contributors report varied caller behaviour, suggesting either different operators using the line or sequential spam campaigns:

• Silent calls: One contributor picked up to a greeting, only to be met with immediate silence and disconnection
• Robocalls: An automated voice conducting a political survey was described as "bit off" by the recipient
• Data harvesting: A caller claiming to conduct market research on private health cover switched tactics mid-call, requesting personal details for supposed health fund comparisons before being cut off

The progression in the health insurance call is telling-initial framing as "market research" followed by a pivot to collecting identifiable information. This is a common low-cost spam tactic designed to normalise the conversation before making the ask.

Report Patterns and Timing

The four reports for 03 9022 0403 span from late August 2025 through early February 2026, suggesting ongoing use of the number. Call attempts reached contributors across different scenarios:

• One caller reached someone who answered directly
• One call missed, with no voicemail left
• Two separate answered calls from different campaign types

The lack of voicemail messages aligns with typical spam behaviour-callers testing numbers for validity or running high-volume campaigns where leaving messages is inefficient. The earliest report dates to August 2025, indicating the number has been in active use for at least six months.
