Silent Call Reports for 08 7133 3603
One contributor has reported receiving repeated silent calls from 08 7133 3603 (also written as 0871333603). The caller made four consecutive calls in quick succession, with no one responding when the recipient answered twice before hanging up. This pattern is typical of silent call nuisance activity, where callers either hang up immediately or remain silent when a person picks up.
The number is allocated as a local service through Optus Networks in South Australia. Silent calls like those from 0871333603 can be particularly frustrating due to their repetitive nature and the uncertainty about intent - whether the calls are automated system testing, callback scams, or deliberate harassment.
Call Pattern from 08 7133 3603
The contributor described receiving four calls in a row from 08 7133 3603, suggesting the caller was persistent in attempting contact. After answering twice with no response from the other end, the recipient decided to block the number to prevent further calls. This rapid-fire calling pattern indicates the number may be involved in systematic dialling rather than a one-off wrong number.
What to Do If You Receive a Call from 08 7133 3603
If 08 7133 3603 calls you:
- Do not: Answer if the number is unknown, stay on the line if you hear silence, or call the number back
- Do: Let it ring through to voicemail, block the number immediately after the first silent call, and avoid pressing any numbers if prompted
- Note: If the caller remains silent and hangs up when challenged, do not attempt to return the call as this may confirm your number is active and lead to more calls
Blocking 0871333603 after experiencing silent calls is a sensible precaution, especially if the calls continue despite not answering.
Why Silent Calls Occur
Silent calls from numbers like 08 7133 3603 can result from several sources. Some are generated by automated systems testing line connectivity or conducting robocall campaigns. Others may be callback scam attempts, where silence indicates the system is waiting to see if you call back. Occasionally, silent calls result from predictive diallers used in legitimate telemarketing, which connect calls faster than operators can respond - but this does not excuse the nuisance.

WRITE A REVIEWFrequently Asked Questions
Why would someone call from 08 7133 3603 and then hang up?
Silent calls like those from 08 7133 3603 often come from automated systems, predictive diallers, or callback scam operations. Some systems dial more numbers than operators can handle, resulting in silence when you answer. Others may be testing whether your number is active. The pattern of four consecutive calls from 0871333603 suggests an automated system rather than a genuine misdial.
Should I call back 08 7133 3603?
No. Do not call back 08 7133 3603 (0871333603). Calling back a number that has made silent calls confirms your number is active and monitored, which can lead to more unwanted contact. This is especially true if the calls are part of a callback scam or aggressive telemarketing campaign.
Is 08 7133 3603 a scam?
The single report we have for 0871333603 describes silent calls rather than a financial scam or impersonation attempt. While the calls are certainly a nuisance, they have not been reported as an advance-fee fraud or credential theft scheme. However, persistent silent calls should still be reported to ACMA and blocked to protect your peace of mind.
Can I block 08 7133 3603 on my phone?
Yes. Most modern phones allow you to block numbers directly through your contacts or call history. On iPhones, swipe on the call history and select 'Block this Caller'. On Android, open the phone app, find the call from 08 7133 3603 or 0871333603, and select 'Block number'. You can also contact your provider (Optus, in this case) to request network-level blocking of the number.
What does it mean that 08 7133 3603 is an Optus local service?
The number 08 7133 3603 is allocated to Optus Networks as a local service in South Australia. This means it was issued as a legitimate local phone number, but does not guarantee the current user is legitimate. Numbers can be spoofed, reassigned, or misused, so the Optus allocation alone does not indicate the source of the silent calls from 0871333603.
