What Happens with Silent Calls from 02 8317 1820
When a contributor answered 02 8317 1820, the line went dead instantly. No message was left, no callback occurred, and no follow-up contact has been reported. This immediate hang-up pattern is typical of robocall or automated dialling systems testing line validity rather than callers with a genuine message to deliver.
The use of a local NSW number (02 8317 1820) may be an attempt to appear legitimate or bypass call screening, as contributors are more likely to answer numbers with local area codes.
Silent Calls and Callback Scam Risks
While the single report of 0283171820 shows only a silent hang-up, contributors should be aware that silent calls sometimes precede callback scams. In these schemes, the initial silent call aims to provoke a return call to an unfamiliar number, which may connect to a premium-rate line or scam operation. Some contributors instinctively redial numbers that have called them, making callback baiting an effective tactic.
What to Do If You Receive a Call from 02 8317 1820
If 02 8317 1820 calls you:
- Do not: Return the call, especially if it disconnects or appears blank
- Do: Let unknown calls go to voicemail, block the number if calls repeat, and avoid pressing any keys or responding to prompts
- Do: Be suspicious of any follow-up contact claiming you called them - you didn't
Blocking 0283171820 after the first silent call prevents any repeated contact from this number.

WRITE A REVIEWFrequently Asked Questions
Why would a number like 02 8317 1820 call and then hang up immediately?
Silent calls from 02 8317 1820 are typically generated by automated dialling systems testing whether phone numbers are active and monitored. Once the system detects an answer, it may hang up or pass the call to an operator. These campaigns are often used to build lists of working numbers for future contact or resale. The contributor who answered 0283171820 experienced this exact pattern.
Should I call back a number like 0283171820 if it calls me silently?
No. Do not return calls to 0283171820 or similar numbers that call silently. Some silent call campaigns are callback scams - they deliberately provoke you to redial, connecting you to premium-rate lines or fraudulent operations. The fact that 02 8317 1820 hung up when answered suggests it was an automated system with no legitimate message to deliver.
Is 02 8317 1820 a scam or just a nuisance?
The single report of 0283171820 shows silent call behaviour consistent with automated dialling systems. While not necessarily a financial scam, silent calls are a nuisance and can indicate your number is being tested for callback schemes or sale to other contact lists.

What does it mean that 02 8317 1820 is a Symbio Networks local service number?
The 02 8317 1820 number is allocated to Symbio Networks, an Australian ISP and telecommunications provider. This does not mean Symbio itself made the call - the number may have been spoofed, reassigned to a customer, or used without authorisation. Many automated dialling campaigns use legitimate provider numbers to appear credible.
How can I stop calls from 02 8317 1820?

What should I do if 02 8317 1820 calls again?
