One contributor reports daily calls from 07 3543 7380 (0735437380) with varying numbers sharing the (07) 3543 prefix, allocated to Netsip Pty Ltd in Queensland.
Recurring Calls from 07 3543 7380
A contributor has reported receiving almost daily calls from 07 3543 7380 (also written as 0735437380), a number allocated to Netsip Pty Ltd in Queensland. What makes this pattern notable is that while the calls consistently originate from numbers sharing the (07) 3543 or (07) 3507 prefix, the specific number changes frequently. The contributor notes that callers never leave voicemail messages, making it impossible to understand the purpose of the contact.
The systematic use of different numbers within the same prefix suggests either a rotating dialling campaign or a multi-line operation using the same service provider. This behaviour is typical of operations attempting to evade blocking by spreading contact attempts across multiple numbers rather than repeating a single caller ID.
What to Do If You Receive Calls from 07 3543 7380
If 0735437380 calls you:
- Do not: Answer calls from unknown numbers, return the call, or provide any personal information if you do answer
- Do: Let calls go to voicemail, block the number immediately after the first call, and note the pattern if multiple related numbers contact you
- Document the pattern: Record the dates and times of calls from 07 3543 7380 and any related numbers sharing the (07) 3543 or (07) 3507 prefix for reference
- Check your accounts: Verify you have not signed up for any services from this provider and confirm no unauthorised accounts exist in your name
How to Report 07 3543 7380

What Our Users Reviewed
Almost every day I get a call from a number that when I Google them they say they are provided by Netsip Pty Ltd. No idea who they are, different number every day, which I then block and delete because they do not leave a message.
Prefix is always (07) 3507 or (07) 3543.

WRITE A REVIEWFrequently Asked Questions
Why do I receive calls from 07 3543 7380 with no voicemail?
Calls that don't leave messages often indicate either automated systems testing for active numbers, or contact attempts where the caller has no specific message to convey. The contributor reporting 0735437380 experienced this pattern almost daily without any voicemail left, which is consistent with systematic number validation rather than legitimate customer service outreach. If you receive calls from 07 3543 7380 with no message, blocking the number is appropriate.
What does Netsip Pty Ltd do?
Netsip Pty Ltd is a Queensland-based telecommunications service provider that allocates phone numbers to customers. The fact that 07 3543 7380 is allocated to Netsip does not necessarily mean Netsip itself is calling you - the number may be assigned to a customer of theirs. However, if calls from 0735437380 are unwanted, you can report this to the ACMA and request investigation into who is using this number.
Should I be concerned about the rotating numbers from the same prefix?
The pattern of calls from 07 3543 7380 and related (07) 3543 or (07) 3507 numbers suggests a deliberate strategy to contact you from multiple numbers, likely to evade blocking. This behaviour is more concerning than a single repeated number, as it indicates intentional persistence. If you continue receiving calls from different numbers within the same prefix, document the pattern and report it to the ACMA at acma.gov.au.
How do I block numbers from 07 3543 7380 and the (07) 3543 prefix?
On most Australian phones, you can block individual numbers directly through your call log or contacts. However, blocking an entire prefix like (07) 3543 may not be possible on standard phones. Instead, block each specific number as it contacts you. If you receive an excessive number of calls from 0735437380 and related numbers, contact your phone service provider - they may be able to apply prefix-level blocking or investigate the source of the calls.
Is this a scam or spam?
Based on the single report, 07 3543 7380 is categorised as uncertain rather than confirmed scam or spam. The lack of voicemail and the rotating numbers suggest unwanted contact, but the specific purpose remains unknown. The contributor has not reported financial loss, threats, or impersonation. To clarify the intent, you could try answering the next call and asking directly, though this is not recommended for unknown numbers. Instead, report the pattern to the ACMA.
Can I find out who is using 07 3543 7380?
While 0735437380 is allocated to Netsip Pty Ltd, the actual caller could be any customer or partner of Netsip. Reverseau's community reports may provide clues if other contributors have answered calls from 07 3543 7380 and identified the caller. You can also contact Netsip directly at their official website to inquire, though they may not disclose customer details. The ACMA can investigate on your behalf if you lodge a formal complaint.
