Silent Call Reports for 02 9053 6743
Two contributors have reported receiving silent calls from 02 9053 6743 (also written as 0290536743), a local service number allocated to Symbio Networks in NSW. The pattern is consistent: the caller answers when picked up, but remains silent, with background noise audible before the line disconnects. Both reports describe hearing a baby crying in the background during these silent moments.
This type of call behaviour is commonly associated with robocall testing or callback scam verification. Silent calls serve no legitimate purpose and are frequently used to identify active phone numbers for follow-up scam attempts.
What Contributors Experienced with 02 9053 6743
The first contributor answered 0290536743 with a greeting, only to encounter silence on the other end. Rather than hanging up immediately, the caller remained on the line long enough for background noise - specifically a baby crying - to become audible before disconnecting. The contributor received a second call from 02 9053 6743 using the identical pattern: silence followed by baby crying sounds, then disconnection.
A separate report noted a missed call from this number with no voicemail left, further suggesting the caller had no legitimate message to convey. The calculated silence and background audio may be deliberate attempts to trigger a callback or confirm the number's active status.

WRITE A REVIEWFrequently Asked Questions
Why am I getting silent calls from 02 9053 6743?
Silent calls from 02 9053 6743 are typically used to test whether your number is active and monitored by a real person. Once confirmed, your number may be sold to other call centres or used for follow-up scam attempts. The background noise and baby crying reported by contributors suggest the calls may originate from a call centre with poor quality control or are deliberately configured to seem legitimately called.
What does it mean if I hear background noise during a silent call from 0290536743?
Background noise like baby crying during a silent call from 0290536743 indicates the caller is likely in a shared space such as a call centre. It does not indicate a legitimate caller trying to reach you. Silent calls combined with background audio are a known pattern used by scammers or robocall operations to confirm active numbers for later targeting.
Should I call back 02 9053 6743?
No. Do not return calls to 02 9053 6743 under any circumstances. Returning the call confirms your number is active and monitored, making it more attractive to scammers. The pattern of silent calls from 0290536743 indicates the caller has no legitimate reason to reach you and is testing your number only.
Is 0290536743 a legitimate business number?
02 9053 6743 is registered as a local service number with Symbio Networks in NSW, but this allocation does not mean the current caller is using it legitimately. Scammers and robocall operations frequently spoof or misuse allocated numbers. The silent-call pattern reported for 0290536743 is not consistent with legitimate business communication.
Why did 02 9053 6743 call multiple times with the same pattern?
Repeated silent calls from 02 9053 6743 using the same pattern suggest automated dialling or deliberate testing by a call centre. The identical behaviour across multiple calls from 0290536743 - silence, background noise, then disconnection - indicates a configured process rather than individual caller error.
What should I do after blocking 02 9053 6743?
After blocking 0290536743, monitor your phone for similar calls from other numbers, as scam operations often use multiple numbers. Report your experience with 02 9053 6743 to ACMA and Reverseau so the pattern is documented. If you receive escalating calls or harassment from related numbers, contact local police.
