Robocall Reports for 07 3543 6704
A contributor has flagged 07 3543 6704 (also written as 0735436704) for persistent robocall activity. The reports indicate a pattern of automated or semi-automated calling behaviour, with the caller systematically varying the last two digits of the number, suggesting a spoofed or randomised dialling campaign originating from Queensland.
The contributor receiving calls from 0735436704 describes a concerning pattern: daily calls that frequently drop to silence when answered, occasional voicemails containing unintelligible audio or "someone babbling", and no coherent message or purpose. This behaviour is typical of robocall operations used to test active phone numbers or harvest data for resale.
Call Patterns and Behaviour
Calls from 07 3543 6704 are occurring daily, with the caller manipulating the final digits to bypass call blocking. This tactic, known as "neighbour spoofing", is designed to make the number appear legitimate and increase answer rates. When the contributor answered calls from 0735436704, the line remained silent rather than connecting to a live operator or recorded message.
The voicemail messages left on 07 3543 6704 calls do not contain coherent speech or a recognisable company name, which distinguishes this from targeted scam campaigns. Instead, the audio appears to be test recordings or a byproduct of automated systems attempting to gather information about the recipient's phone activity.
What to Do If You Receive a Call from 07 3543 6704
If 0735436704 calls you:
- Do not: Answer repeated calls from this number, return the call, or engage with any voicemail content
- Do: Block 07 3543 6704 immediately in your phone's contacts, let calls go to voicemail, and do not respond to callback requests
- Do: Report the number to the Australian Communications and Media Authority if calls continue after blocking
Robocalls from numbers like 0735436704 rely on high call volumes and low engagement rates. Blocking and not answering is the most effective response, as it signals to automated systems that your number should be deprioritised.

WRITE A REVIEWFrequently Asked Questions
Why does 07 3543 6704 keep changing the last digits?
Robocall operations use software to automatically vary phone numbers during dialling campaigns. When you report 0735436704, scammers simply shift to a similar number like 07 3543 6705 to evade blocks. This is called "neighbour spoofing". Report the entire pattern to ACMA rather than individual variations.
Should I answer calls from 07 3543 6704 to find out who's calling?
No. Do not answer calls from 0735436704. Robocall operators use answer rates to validate phone numbers for resale to other scammers. Answering confirms your number is active and increases call volume. Block and ignore instead.
What does the garbled voicemail from 07 3543 6704 mean?
The babbling or unintelligible audio from 0735436704 is typically a test recording used by robocall systems to check if voicemail is active on your line. It has no scam message or demand-it's an automated probe. Delete and report to ACMA.
Is 07 3543 6704 a legitimate Queensland business number?
The number 0735436704 is allocated to a local service provider (NetSIP Pty Ltd in Queensland), but this does not mean the calls are legitimate. Robocall services often use compromised or spoofed business allocations. The caller behaviour-daily silent calls and garbled audio-confirms this is not a genuine business outreach.
How do I block 07 3543 6704 and similar numbers?
On most Australian phones, you can block 0735436704 directly in your Contacts app or Phone settings. For systematic blocking of neighbour spoofing, enable "Filter Unknown Senders" (iPhone) or "Spam Protection" (Android). Some telcos like Telstra and Optus offer free call filtering services. Report the pattern to ACMA so they can take action at network level.
What should I do if I accidentally called back 07 3543 6704?
If you returned a call to 0735436704, do not provide any personal information. Hang up immediately if someone answers. Monitor your phone bill for unexpected charges. If the number was truly a robocall service, calling back simply confirms your number is monitored and may increase contact attempts. Block the number and move on.
