Robocall Reports for 03 9039 2778
A contributor has flagged 03 9039 2778 (also written as 0390392778) for suspicious robocall behaviour. The caller triggered an automated response immediately upon connection, delivering only the word "Goodbye" before disconnecting. This pattern is typical of robocall systems testing active numbers or harvesting contact information for follow-up scam attempts.
The number is allocated to an Optus local service in Victoria, making it appear legitimate at first glance. However, the automated hang-up after a single robotic utterance is a strong indicator of malicious intent rather than legitimate business communication.
What Happened on the Call from 03 9039 2778
The contributor answered when 0390392778 called. Instead of a live person or standard voicemail greeting, they heard a synthesised voice say "Goodbye" followed by immediate disconnection. No business name was offered, no message was left, and the call ended within seconds.
This behaviour suggests the robocall system was designed to confirm the number answers calls, marking it as "active" in a database for future scam campaigns. Robocalls of this type often precede more aggressive follow-up attempts from the same number or related numbers days or weeks later.
Why Robocalls Use This Tactic
Automated "ping" calls from 03 9039 2778 serve a specific purpose in scammer workflows. By triggering a response and immediately hanging up, the system confirms your number is monitored by a real person.

Contributors who answer such calls from 0390392778 are essentially confirming their number to criminal operations. The brevity and automation suggest this wasn't human-initiated fraud, but rather the first mechanical probe in a multi-layered attack sequence.
