Immediate hang-ups often indicate the caller is using automated systems to test whether numbers are active. The contributor's report of 0383911504 hanging up right after they said hello is typical of this behaviour. It may also be a misdirected call or a system checking line validity.

A single hang-up is generally not cause for alarm, but it's worth noting. If you receive repeated calls from 03 8391 1504 that hang up, blocking the number and reporting to ACMA is reasonable. One contributor has already reported this behaviour, so monitoring for patterns is sensible.
Is 03 8391 1504 a legitimate Optus number?
The number 0383911504 is allocated to Optus Networks in Victoria. However, allocation does not guarantee legitimacy. If you expected a call from Optus, contact them directly using the number on your bill or their official website rather than returning a call to 03 8391 1504.
Can I block 0383911504 on my phone?
Yes, most modern phones allow you to block numbers. After receiving a call from 03 8391 1504, you can add it to your blocked contacts or use your phone's native call-blocking feature. Many service providers also offer filtering options for managing nuisance calls.

Could the hang-up from 03 8391 1504 be a callback scam?
Callback scams typically occur when callers encourage you to ring back a premium number. The contributor's report describes a straightforward hang-up, not a callback request. However, if you do receive any request to call back an unfamiliar number, avoid doing so and verify independently through official channels.
