Silent Call and Spam Reports for 02 5350 6861
Five contributors have reported activity from 02 5350 6861 (also written as 0253506861), a local NSW number allocated to Symbio Networks Pty Ltd. The reports describe a pattern of unwanted calls characterised by immediate hang-ups and prolonged silence, with some contributors noting repeated contact over several months.
Two explicit silent call reports indicate the caller remains on the line without speaking when the recipient answers. The remaining reports describe calls that disconnect as soon as the recipient engages, or calls that leave no voicemail message. One contributor noted the behaviour as particularly strange, suggesting deliberate contact rather than accidental dialling.
What Callers from 02 5350 6861 Do
Contributors report two distinct patterns from 0253506861. The first involves silent calls where the line stays open but no one speaks, even after the recipient greets the caller. One contributor described answering to find only silence with no message left afterward. Another reported the same experience, receiving a call from 02 5350 6861 that produced only quiet on the line.
The second pattern involves immediate disconnection. One contributor noted that as soon as they said hello, the caller hung up without explanation. Another report describes the number calling and hanging up without leaving a message. These rapid disconnections without attempted communication distinguish 0253506861 from standard telemarketing calls where callers typically attempt a sales pitch or leave recorded messages.
Report Patterns and Timing
Community reports for 02 5350 6861 span from August 2025 through February 2026, indicating sustained activity over at least six months.

No specific time-of-day patterns emerge from the available reports, though calls occurred across different hours including early morning (06:42, 07:37) and mid-morning (09:19, 10:19).

WRITE A REVIEWFrequently Asked Questions
Why would someone call from 02 5350 6861 and stay silent?
Silent calls from 0253506861 are often used to verify that a phone number is active and monitored by a real person. This information is then sold to other scammers or used to target the number with more sophisticated scams later. The contributor reports of hang-ups and silence from 02 5350 6861 suggest automated verification activity rather than accidental dialling.
Is 02 5350 6861 a dangerous scam?
Current reports for 0253506861 describe nuisance and spam behaviour rather than active financial scams. However, silent calls are a recognised warning sign that your number has been flagged as active. If silent calls from 02 5350 6861 escalate to other unwanted contact, it may indicate your number has been compromised or sold to scam operators.
Should I call back 0253506861?
No. Do not attempt to call back 02 5350 6861. Callback attempts from silent call numbers can confirm your number is monitored and trigger additional unwanted contact. Blocking the number and reporting it to ACMA is the recommended approach instead of engaging.
Why do I keep getting calls from 02 5350 6861?
One contributor reported being hit repeatedly with spam calls from this number over several months, suggesting 0253506861 is part of a sustained calling campaign. Silent calls and hang-ups may indicate automated dialling targeting multiple numbers in batches. Blocking and reporting to the Do Not Call Register (donotcall.gov.au) are the most effective ways to stop repeated contact.
What should I do if 02 5350 6861 keeps calling me?
If calls from 0253506861 continue, block the number immediately in your phone settings. Register with the Do Not Call Register at donotcall.gov.au and report the repeated calls to ACMA at acma.gov.au. If the pattern escalates or changes, document the dates and times, then report again to both agencies. Contributing your experience to Reverseau also helps warn other Australians about this number.
Is 02 5350 6861 a legitimate business number?
