Silent Call Reports for 0400 247 493
One contributor has reported a silent call from 0400 247 493 (also written as 0400247493). When the call was answered, the contributor could hear voices in the background but received no response or greeting from the caller. This type of behaviour is characteristic of robocall systems testing active numbers or callback scam operations attempting to verify contact details.
The number is allocated to Telstra Limited as a mobile service, which is commonly spoofed or reassigned in nuisance call campaigns.
What Callers from 0400 247 493 Do
Silent calls typically occur in a few scenarios. The contributor's experience of hearing background voices but no direct engagement suggests automated systems or call centre operations rather than a direct scam attempt. These calls often serve as number verification tools - if you answer, the caller's system confirms the number is active and likely to be monitored by a person, making it a target for future calls.
Some silent calls are generated by predictive diallers used in telemarketing campaigns that connect to the next available operator only when a person answers. Others may be callback scams where the system simply records that a live person answered 0400247493 for later contact.
Call Patterns and Timing
The reported call from 0400 247 493 came in during early morning hours (07:49 UTC), which is outside typical business hours in most Australian time zones. This timing pattern is sometimes associated with overseas call centres operating to Australian hours, though a single report provides limited pattern data.

WRITE A REVIEWFrequently Asked Questions
Why did 0400 247 493 call me and stay silent?
Silent calls from 0400247493 are typically generated by automated systems testing whether your number is active and answered by a real person. The background voices heard by the contributor suggest a call centre environment, indicating the system may be confirming your number for future marketing or scam contact attempts. Legitimate businesses always identify themselves when you answer.
Should I call back 0400 247 493?
No. Do not call back 0400247493. Callback scams deliberately trigger silent calls to make recipients curious enough to return the call, generating revenue for overseas operators or capturing your number for repeated contact. Any legitimate caller will leave a voicemail message.
Is 0400 247 493 a scam or just nuisance?
One community report describes 0400247493 as a silent call - a nuisance behaviour that may be part of a larger scam operation. Silent calls alone aren't always scams, but they're used by scammers and robocallers to verify active numbers. If calls from 0400 247 493 repeat or escalate to actual contact attempts, report it to ACMA.
Can I block 0400 247 493 on my phone?
Yes. Most Australian phones allow you to block numbers in your call settings or contacts app. After blocking 0400247493, future calls will go directly to voicemail. If multiple silent calls from 0400 247 493 arrive in quick succession, blocking is recommended before reporting to ACMA.
Why is 0400 247 493 a Telstra number if it's suspicious?
Telstra mobile numbers like 0400247493 are legitimate allocations, but they can be spoofed (caller ID faked) or compromised through account misuse. The allocation data shows the number is registered to Telstra Limited, but this doesn't guarantee the actual caller is Telstra or using it legitimately. Always verify any caller claiming to be from a company by calling their official number directly.
What should I do if 0400 247 493 calls me again?
If you receive repeated calls from 0400247493, block the number immediately and report it to ACMA at acma.gov.au. Include the date, time, and description of the call. If you answer and hear silence again, hang up without responding. Do not try to communicate or call back - this only encourages further contact.
