Silent Call Reports for 03 8654 0000

Two contributors have reported receiving silent calls from 03 8654 0000 (also written as 0386540000), a Victorian local service number allocated to Optus Networks. Both reports describe the same pattern: the call connects but no voice is audible, replaced instead by unexplained background chatter or noise. This type of calling behaviour often indicates robocall systems testing lines or callback scam operations that disconnect when a human answers.

One earlier report from May 2024 notes that 0386540000 was used by ANZ Bank for outbound marketing calls about banking opportunities. This suggests the number may be legitimately allocated, though the recent silent call reports indicate it could now be used for nuisance calling or has been spoofed by third parties.

What Callers from 03 8654 0000 Do

Contributors receiving calls from 03 8654 0000 describe silence upon answering, with faint or odd background noise in the background rather than a greeting or recorded message. One contributor noted the number "keeps calling" with this same silent pattern, suggesting either a robocall system cycling through numbers or a deliberate callback scam strategy where silence is used to trigger a return call.

Unlike typical telemarketing or scam calls where a message plays immediately, these silent calls from 03 8654 0000 suggest an automated system that may be:

• Testing whether a line is active (number validation for later scam targeting)
• Waiting for the recipient to speak first, then attempting a callback scam
• A malfunctioning robocall system

Report Patterns and Timing

Both silent call reports for 03 8654 0000 were received recently, within the same day in January 2026. The calls were answered by contributors, meaning they picked up the line directly rather than missing the call. One contributor mentioned the number calls repeatedly, indicating a pattern of persistence rather than a one-off misdial.

The earlier legitimate report about ANZ Bank using 0386540000 for marketing calls occurred in May 2024, suggesting the number has shifted from legitimate business use to silent/nuisance calling activity, or has been compromised for spoofing.

What to Do If You Receive a Call from 03 8654 0000

If 03 8654 0000 calls you:

• Do not: Speak, confirm your name, or stay on the line waiting for a response
• Do not: Return the call or press any keys
• Do: Hang up immediately and block the number
• Do: Let repeated calls go to voicemail rather than answering
• Do: Report the number to ACMA if calls persist after blocking

Silent calls are often used in callback scams where the perpetrator records your voice saying "yes" or similar, then uses that recording to falsely authorize transactions. Do not engage with silence on the line.
