Phishing Reports for 07 3507 1212
Two contributors have reported suspicious activity from 07 3507 1212 (also written as 0735071212), a Queensland-based local service number. The reports suggest coordinated phishing behaviour rather than standard telemarketing, with one contributor specifically noting the caller attempted to extract information through invalid extension prompts before disconnecting.
The pattern indicates 0735071212 may be part of a phishing operation designed to identify active numbers or gather personal data during brief interactions. One report mentions the caller provided no business context before attempting the invalid extension tactic, a common technique used to confuse or stall recipients while capturing information.
What Callers from 07 3507 1212 Say and Do
When a contributor answered the call from 07 3507 1212, the caller responded with "that is not a valid extension" before immediately hanging up. This tactic is characteristic of phishing attempts designed to prompt the recipient to provide information or identify themselves while explaining the situation.
The second contributor who tried to return the call found 0735071212 was disconnected or not accepting inbound calls, suggesting the number may have been temporarily active or spoofed. This behaviour pattern-incoming call followed by inability to callback-is typical of phishing operations that don't expect or want return contact.
Report Timeline and Patterns

The missed call report shows the contributor took precaution by not immediately returning the call, but found 07 3507 1212 disconnected when they attempted contact later.
The Queensland allocation for 0735071212 through NetSIP Pty Ltd indicates a VoIP service rather than traditional landline infrastructure, which aligns with phishing operation patterns that use cloud-based calling systems to avoid traditional carrier accountability.

WRITE A REVIEWFrequently Asked Questions
What does 'invalid extension' mean when calling 07 3507 1212?
One contributor reported the caller from 07 3507 1212 said "that is not a valid extension" immediately upon answering, then hung up. This is a phishing tactic designed to prompt you to explain yourself or provide information about who you are. Do not engage-hang up immediately. The caller has no legitimate reason to reference extensions when you didn't mention one.
Why is 0735071212 disconnected when I try to call back?
A contributor who attempted to callback 0735071212 found the number disconnected or not accepting calls. This is typical of phishing operations that use temporary or spoofed VoIP numbers. They expect one-way calling only and don't want return contact. Never assume a disconnected callback means the number is inactive-it often indicates deliberate avoidance.
Is 07 3507 1212 a real business number?
The allocation data shows 07 3507 1212 (0735071212) is registered to NetSIP Pty Ltd as a VoIP local service in Queensland. While the allocation is registered, the reports suggest it's being used for phishing rather than legitimate business. Do not assume a valid allocation means safe communication-scammers frequently use legitimate VoIP providers.
What should I do if 0735071212 calls and asks about extensions?
If you receive a call from 0735071212 asking about extensions or providing confusing messages, hang up immediately. Do not provide your name, department, role, or any identifying information. Block the number and do not attempt to return the call. Report it to ACMA at acma.gov.au if you believe it's a phishing attempt.
Should I answer calls from Queensland number 07 3507 1212?
If 07 3507 1212 is unknown to you, do not answer. Both community reports about 0735071212 suggest phishing activity rather than legitimate calling. Let unknown calls go to voicemail. If the call is legitimate, the caller will leave a message or contact you through verified channels.

Report 07 3507 1212 (0735071212) to ReportCyber at cyber.gov.au if personal or financial data was requested, or to ACMA at acma.gov.au for general phishing activity.
