WRITE A REVIEWFrequently Asked Questions
What is a robocall and why did 03 9111 2442 leave a voicemail saying 'bye'?
A robocall is an automated call using pre-recorded messages or text-to-speech technology. The voicemail from 0391112442 saying only 'bye' is unusual and likely either a system malfunction or an intentional nuisance tactic. Legitimate businesses do not leave voicemails with single words; this suggests the call from 03 9111 2442 was not a genuine business inquiry.
What does a silent call mean, and why did I hear background chatter when 0391112442 called?
A silent call is when someone calls but hangs up immediately, often without saying anything. The background chatter reported during the call from 03 9111 2442 suggests a call centre environment, which is typical of firms using silent calls to verify working phone numbers for future targeting or to build lists of active numbers for scams.
Should I call back 03 9111 2442 if they leave a voicemail?
No. Do not call back 0391112442. Returning the call confirms your number is active and monitored, which may lead to more calls. If you receive another call from 03 9111 2442, block the number and report it rather than engaging.
Is 03 9111 2442 a legitimate business number?
The number 0391112442 is registered as a local service with Symbio Networks Pty Ltd in Victoria, which is a legitimate internet and telecommunications provider. However, the number's allocation does not guarantee legitimate use - it may have been compromised, spoofed, or misused by scammers. The reports indicate the number is being used for nuisance calling, not legitimate business.
How can I block 03 9111 2442 permanently on my phone?
On most Australian phones, open your recent calls list, find 03 9111 2442 (0391112442), and select 'Block' or 'Add to Blocklist'. iPhone users can use the Silence Unknown Callers feature in Settings.

If I received a call from 03 9111 2442, what information should I report?
When reporting 0391112442 to ACMA or Scamwatch, provide the date and time of the call, whether you answered or it was voicemail, any words spoken (like the 'bye' message), and the caller's behaviour (silent call, hang-up, background noise). This information helps authorities identify patterns and track the source of calls from 03 9111 2442.
