WRITE A REVIEWFrequently Asked Questions
Why would someone call from 0400 611 708 and leave a silent voicemail?
Silent calls followed by blank voicemails are typically callback scams or automated systems confirming active numbers. Callers from 0400 611 708 may be testing whether your number will respond to return calls, which they can then exploit by claiming you called them first. This is a common opening tactic in callback scams.
Is 0400611708 a real Telstra number or is it spoofed?
The number 0400 611 708 is allocated to Telstra as a mobile service. However, that doesn't guarantee the caller is actually using a legitimate Telstra account - the number may be spoofed using VoIP technology or the account itself may be compromised. Either way, the silent call pattern suggests scam activity rather than legitimate contact.
What should I do if I already called back 0400611708?
If you've already called back 0400 611 708, avoid providing any personal information, bank details, or passwords. If you're concerned about what information you may have shared, contact your bank and monitor your accounts for suspicious activity. Report the number to ACMA at acma.gov.au and consider blocking 0400611708 on your phone.
Why did 0400 611 708 call twice in quick succession?
Multiple calls from 0400611708 in quick succession often indicate an automated callback scam system attempting to reach different numbers or testing whether your line is active. This persistence is designed to increase the likelihood that you'll notice the missed calls and become curious enough to call back.
Can I block 0400 611 708 on my phone?
Yes, most Australian mobile phones allow you to block numbers directly. Add 0400 611 708 to your blocked contacts or use your phone's built-in spam filtering. If you have a Telstra service, you can also ask Telstra support to help block 0400611708 at the network level.
Should I delete the voicemail from 0400611708 or keep it as evidence?
If you want to report the calls from 0400 611 708 to authorities like ACMA or police, saving the voicemail and noting the exact time and date of the silent call can serve as documentation. However, there's no safety benefit to keeping it - once documented, you can safely delete the empty message from 0400611708 and block the number.
