Spam Reports for 03 9970 7639
A single contributor has reported receiving an unwanted call from 03 9970 7639 (also written as 0399707639). The caller did not leave a voicemail, and the contributor let the call go to voicemail rather than answering. This pattern suggests either a test call or automated dialling, both common in spam operations.
The number is allocated as a local service through NetSIP Pty Ltd in Victoria, which is a legitimate VoIP provider. However, legitimate service providers can have their systems compromised or numbers spoofed by spammers, so allocation data alone does not indicate whether the actual caller is legitimate.

WRITE A REVIEWFrequently Asked Questions
Should I answer if 03 9970 7639 calls me?
No. If you don't recognise the number, let it go to voicemail. One contributor reported receiving a call from 03 9970 7639 that left no message, which is typical of spam or robocall testing. If the call is legitimate, the caller will leave a voicemail or you can verify them independently before calling back.
What does it mean that 0399707639 is listed as a local service?
The number 0399707639 is allocated to NetSIP Pty Ltd as a local VoIP service, based in Victoria. However, this does not guarantee the caller is legitimate. Spammers frequently use VoIP numbers that appear to be local numbers, and sometimes compromise legitimate VoIP accounts. The fact that one contributor reported 03 9970 7639 as unwanted suggests the number may be misused regardless of its allocation.
Why didn't the caller from 03 9970 7639 leave a voicemail?
Spam and robocall operators often don't leave voicemail messages because they're calling thousands of numbers with automated systems. The contributor who received a call from 03 9970 7639 reported it as an unwanted ring with no voicemail, which is a common spam pattern. Legitimate businesses almost always leave a message explaining why they're calling.
Can I block 03 9970 7639 on my phone?
Yes. Most smartphones allow you to block specific numbers. If 0399707639 calls you more than once, blocking it will prevent future calls from reaching your phone. You can also report repeated calls from 03 9970 7639 to the ACMA (acma.gov.au) and register on the Do Not Call Register if it's a marketing call.
Should I call back 03 9970 7639 if they left a message?
Only if you recognise the caller or have independently verified who they are. Do not return a call to 0399707639 based solely on the number appearing on your phone. If it's a legitimate business, look up their official phone number online and call that instead. Calling back unknown numbers can expose you to additional unwanted contact.
How do I report unwanted calls from 0399707639 to authorities?
Report the call from 03 9970 7639 through these official Australian services: the Do Not Call Register (donotcall.gov.au) if it's marketing, the ACMA (acma.gov.au) for spam or harassment, or Scamwatch (scamwatch.gov.au) if it involved a scam attempt. You can also contribute your experience to Reverseau to help other Australians.
