Suspicious Activity Reports for 31673655083
Two contributors have reported receiving missed calls from 31673655083 on their Australian landlines. Both instances involved the same behaviour pattern: incoming calls with no voicemail message left behind. The lack of communication attempt suggests the caller may be testing line validity or conducting number harvesting.
31673655083 appears to be an international number outside standard Australian dialling codes, which raises additional questions about call origin and intent. Contributors flagged 31673655083 as suspicious based on the silent call behaviour rather than any direct interaction with the caller.
Call Patterns and Behaviour
Both reports of 31673655083 occurred within two seconds of each other on 22 June 2026, suggesting either automated dialling or rapid sequential calls to multiple numbers. The fact that neither call generated a voicemail is notable - legitimate businesses typically leave messages when reaching voicemail, while suspected scam or robocall operations often do not.
The targeting of landline numbers (rather than mobile) is consistent with batch calling campaigns that use automated systems to identify active phone lines. Contributors who received calls from 31673655083 did not answer, which prevented any direct contact or social engineering attempt.

WRITE A REVIEWFrequently Asked Questions
Is 31673655083 a real Australian phone number?
No. 31673655083 does not follow Australian phone number formats (which start with 02, 03, 04, 07, 08, or 1800/1300 prefixes). This appears to be an international number, possibly from Europe based on the digit pattern. International calls making no attempt to leave messages are often associated with scam or robocall operations.
Why would 31673655083 call and not leave a voicemail?
Silent or callback scams frequently use this tactic to identify valid, active phone numbers without leaving evidence. The caller from 31673655083 may be testing which numbers are monitored, planning a follow-up attempt, or attempting to provoke a callback that generates charges on your line. Legitimate callers almost always leave messages.
Should I call 31673655083 back?
No. Do not return calls to 31673655083 or any unknown international number. Callback scams deliberately omit voicemail messages to encourage you to ring back, which can result in premium rate charges. If the call was important, the caller would leave a message or contact you through official channels.
How can I block 31673655083 on my landline?
Most modern landline phones and routers include call-blocking features. You can add 31673655083 to a blacklist or contact your phone provider (Telstra, Optus, Vodafone, or NBN provider) to request blocking of the number. Some providers offer free spam/scam call filtering services.
What should I do if 31673655083 calls repeatedly?
If 31673655083 continues calling after you've blocked it, report the number to ACMA at acma.gov.au and document each call with date and time. Persistent international calls may indicate your number has been sold to scam operations. Consider registering with the Do Not Call Register at donotcall.gov.au to reduce unwanted calls generally.
Could 31673655083 be a legitimate overseas business trying to reach me?
Possibly, but unlikely without a voicemail. Legitimate international businesses leave messages explaining who they are and why they're calling. The pattern reported for 31673655083-multiple calls with no message-is typical of automated scam or robocall systems, not genuine business enquiries. If you're expecting a call from overseas, you would likely recognise the context or have a prior arrangement.
