WRITE A REVIEWFrequently Asked Questions
What does it mean if someone calls from 03 9771 7954 and hangs up immediately?
One contributor experienced this exact behaviour from 0397717954. An immediate hang-up after you answer is often a fishing tactic to confirm your number is active and answered by a real person. Scammers use this information to target the number later with actual scam calls or to sell the number to other scammers. Do not call the number back.
Is 03 9771 7954 a legitimate Optus number?
While 0397717954 is allocated to Optus Networks as a local service number in Victoria, the allocation itself does not guarantee legitimacy. Scammers can use legitimate phone number ranges by spoofing or through compromised accounts. Community reports about 03 9771 7954 suggest it is being used for scam or suspicious activity.
Should I answer calls from 03 9771 7954?
No. Contributors who answered 0397717954 experienced either a hang-up (fishing attempt) or were targeted with a scam call. If you do not recognise the number, let it go to voicemail. If it calls again, block 03 9771 7954 immediately.
What should I do if I answered 03 9771 7954 and just said hello?
Saying hello to 0397717954 does not put you at immediate risk, but it does confirm to the caller that your line is active. This is why they may have hung up. Block the number now and monitor for follow-up calls. If 03 9771 7954 continues to call, report it to ACMA at acma.gov.au.
Can I report 03 9771 7954 to the Do Not Call Register?
The Do Not Call Register (donotcall.gov.au) applies to legitimate telemarketing. Scam calls like those from 0397717954 often use spoofed or temporary numbers and ignore the register entirely. Instead, report 03 9771 7954 directly to ACMA or Scamwatch, and block the number on your phone.
Why would a scammer use a legitimate-looking Optus number like 03 9771 7954?
Legitimate Australian number ranges like 0397717954 appear more trustworthy to callers than overseas numbers or obvious spoofs.

This is why 03 9771 7954 may be used for fishing attempts or scam calls - the format itself is designed to bypass your initial caution.
