Silent Calls and Telstra Impersonation Reports for 03 9003 4594

Four contributors have reported activity from 03 9003 4594 (also written as 0390034594) involving silent calls, potential robocall behaviour, and at least one attempt to impersonate Telstra. The reports suggest this number is being used for multiple problematic calling tactics rather than a single scam campaign.

The most concerning pattern involves silent calls where recipients answer only to encounter silence or immediate disconnection. One contributor specifically noted the characteristic behaviour of automated number verification, where callers are testing whether a phone number is actively monitored by a person. Another report describes a caller claiming to represent Telstra and requesting assistance with IP address configuration, despite the recipient having no Telstra internet service.

What Callers from 03 9003 4594 Do

When recipients have answered calls from 03 9003 4594, the behaviour varies considerably. One contributor received a call where the caller claimed to be from Telstra and attempted to discuss configuring an IP address. This is a red flag because legitimate Telstra support would not call unsolicited to discuss IP configuration, and the caller's claim was immediately contradicted by the fact the recipient had no Telstra internet service.

In two separate instances, callers from 0390034594 have used the silent call tactic. One report describes silence followed by disconnection, consistent with automated systems testing whether a number belongs to an active subscriber. Another contributor answered to silence and the immediate hang-up, with the observation that this felt like machine-driven activity designed to identify which numbers are being actively answered.

A fourth report mentions the number is apparently linked to financial planners in Adelaide, though the contributor provided limited detail on the nature of this connection.

Report Patterns and Timing

The four reports from 03 9003 4594 span from late January through late February 2026. The most recent report occurred on 25 February, and another on 22 February, suggesting ongoing activity. Two reports came from answered calls and two from missed or ignored attempts.

One contributor noted the call came from a Melbourne number (though this may refer to the area code rather than origin). The mix of silent calls, robocall characteristics, and impersonation attempts suggests either multiple scammers using the same number or a single operation testing different tactics.

What to Do If You Receive a Call from 03 9003 4594

If 03 9003 4594 calls you:

• Do not: Answer and remain on the line if you hear silence, do not provide personal information or agree to any technical assistance, do not confirm your identity or availability
• Do: Let calls go to voicemail, block the number immediately after a suspicious call, hang up if a caller claims to be from Telstra or another company and discusses technical configuration you did not request
• Verify independently: If you receive a call about a service you use (like Telstra), hang up and call the official customer service number from the company's website or your bill to confirm whether they actually called you

Silent calls and robocalls of the type reported for 0390034594 often indicate your number is being harvested or tested for sale to scammers. Blocking prevents the caller from learning whether you actively monitor this line.
