Repeated Calls from 02 8318 0865 with No Message
A contributor has reported receiving calls from 02 8318 0865 (also written as 0283180865) that follow an unusual pattern: exactly 2 calls each time, with no voicemail message left behind. The number is allocated to Symbio Networks Pty Ltd in NSW as a local service.
What makes this report notable is the contributor's observation of a broader pattern across related Sydney numbers. The same calling behaviour has been reported from other numbers in the 8318, 8317, and 8320 ranges, all within the same Sydney region. This consistency suggests a coordinated operation rather than random calling.
The Two-Call Pattern
The contributor describes receiving exactly 2 calls from 02 8318 0865 in succession, with silence on both occasions and no attempt to leave a voicemail message. This deliberate pattern of multiple calls without any voice message is unusual and can indicate several possibilities: callback scams attempting to trigger a return call, robocall testing, or deliberate harassment.
The fact that similar behaviour occurs across multiple numbers in the 8317, 8318, and 8320 ranges suggests the calling may be coordinated from a single operation using multiple lines. This technique distributes calls across numbers to avoid immediate blocking or complaints.
What to Do If You Receive a Call from 02 8318 0865
If 0283180865 calls you:
- Do not: Return the call or engage if you answer
- Do: Let it go to voicemail, block the number, and keep a record of the date and time
- Do: Be aware that callback scams rely on you initiating contact after a missed call
- Do: Report the pattern if you receive calls from related numbers in the 8317, 8318, or 8320 ranges

WRITE A REVIEWFrequently Asked Questions
Why would someone call twice and not leave a message from 02 8318 0865?
The two-call pattern from 0283180865 without voicemail often indicates a callback scam tactic. The caller hopes you'll return the call out of curiosity, generating revenue for them. Alternatively, it can be robocall testing to confirm active numbers. Avoid returning any call you don't recognise.
Is the pattern across 02 8318, 02 8317, and 02 8320 connected?
The contributor reporting 02 8318 0865 noted the same two-call, no-message pattern across related Sydney numbers in the 8317, 8318, and 8320 ranges. This consistency suggests a single operation using multiple lines to distribute calls and avoid being blocked or reported as a single number.
Should I block 02 8318 0865?
Yes. If 0283180865 calls you with no message, blocking is appropriate. Given the reported pattern across multiple similar numbers, you may also want to block the related numbers (02 8317 and 02 8320 ranges) if you receive the same behaviour.
What should I do if I answer a call from 02 8318 0865?
If you answer and hear silence or no clear purpose, hang up immediately. Do not stay on the line, do not provide any information, and do not ask questions. End the call and block 0283180865 in your phone settings.
Could 02 8318 0865 be a legitimate business?
The number is allocated to Symbio Networks Pty Ltd as a local service in NSW. However, legitimate businesses do not use the two-call, no-message tactic reported for 0283180865. If you have a genuine reason to contact Symbio, call their main business line rather than returning a missed call from this specific number.
How common are coordinated multi-number calling campaigns like the 8317, 8318, 8320 pattern?
Multi-number campaigns are increasingly common among scammers and harassment operators. By spreading calls across many numbers in the same range, as reported for 02 8318 0865, they reduce the visibility of any single number and make blocking more difficult. Reporting the pattern across all related numbers to ACMA helps authorities identify these operations.
