Why Silent Calls from 03 9003 6688 Occur
Silent calls serve several purposes for bad actors. Some are used to verify whether a number is active and monitored by a real person, feeding that data back into scam or spam databases.

The silence itself is intentional, designed to provoke curiosity and a return call.

Block 0390036688 in your phone settings immediately. Do not return the call under any circumstances, as this confirms your number is active and may result in more calls. If the calls persist after blocking, report the number to the ACMA at acma.gov.au.
Why would someone call from 03 9003 6688 and say nothing?
Silent calls from 0390036688 are typically used to verify whether your phone number is in use. This data is sold to spam and scam operations or used in callback scam schemes where they hope you'll call back out of curiosity, potentially incurring charges.
Is it safe to call back a number like 03 9003 6688 that called me silently?
No. Never call back 0390036688 or any silent caller. Returning the call confirms your number is active and monitored, making you a target for future campaigns. It may also connect you to a premium service with associated charges.
Could 03 9003 6688 be a legitimate business testing their phone system?
Legitimate businesses do not conduct silent call testing from random numbers. If a business needs to contact you, they will identify themselves when you answer. Silent calls from 0390036688 are not standard practice for any reputable organisation.
Should I report silent calls from 03 9003 6688 to anyone besides the ACMA?
