Two contributors have reported receiving calls from 04 9987 5998 (also written as 0499875998) where no voicemail was left behind. Both reports came from missed calls on this Telstra mobile number, with callers making no attempt to communicate beyond the initial contact.

Should I be concerned about missed calls from 04 9987 5998 with no voicemail?
Missed calls with no voicemail from 04 9987 5998 are not necessarily malicious, but they warrant caution. Two Reverseau contributors reported this pattern - both received calls but no message was left. Legitimate callers usually leave voicemail. If calls from 0499875998 persist, blocking is recommended.
What should I do if 04 9987 5998 keeps calling me?
If you receive repeated calls from 04 9987 5998 without messages, block the number on your phone. Most modern phones allow blocking via the call history or contacts app. If you're a Telstra customer, you can also enable network-level blocking through your account or request assistance from Telstra support.
Is 0499875998 a known scam number?
Based on current Reverseau community reports, 0499875998 has only two reports, both describing mystery missed calls with no voicemail. This does not match the pattern of active scams, which typically involve repeated contact and specific claims. However, if your experience differs, please report it to help identify any emerging activity from this Telstra number.
Why would someone call from 04 9987 5998 and not leave a message?
There are several possible explanations: accidental dialling, automated systems testing number validity, or reconnaissance calls. Contributors who reported 04 9987 5998 did not provide additional context. If the calls are infrequent one-offs, accidental contact is most likely. Persistent calls suggest intentional contact.
Can I report 04 9987 5998 to authorities?
Yes. If calls from 0499875998 become harassing or frequent, report to the Australian Communications and Media Authority (acma.gov.au).

You can also contribute your experience to Reverseau to help identify the caller's purpose.
Is 04 9987 5998 a scammer using a spoofed Telstra number?

If 0499875998 calls again, note the exact time and contact Telstra directly to verify if the call originated from their network.
