Silent Calls and Property Spam from 04 4013 6141
Eight contributors have reported activity from 04 4013 6141 (also written as 0440136141), with a pattern emerging around silent calls paired with unsolicited property sales pitches. Three separate reports specifically mention the caller hanging up immediately or after silence when answered, suggesting 0440136141 operates as a verification or "probe" call to confirm active phone numbers. One contributor noted this tactic: "0440136141 is used to test the receiver so phone. It'll hang up when I picked it up. Later there'll be a local landline phone call, trying sell sth."
The remaining activity from this Optus mobile number centres on property-related spam, with callers offering house valuations and property sales information without consent. Multiple contributors on the Do Not Call Register have received calls from 04 4013 6141 attempting to collect personal information for valuation purposes.
What Callers from 04 4013 6141 Say
Reports indicate two distinct caller patterns associated with 0440136141. The first involves silent calls where the line goes dead immediately or after a few seconds of silence. Contributors describe picking up to silence, attempting to respond, and the caller disconnecting within seconds. This behaviour is consistent with automated verification systems testing number validity.
The second pattern involves direct sales pitches about property in the local area. One caller claiming to represent "Tony Walker from Shead Property" left contact information via voicemail. Another contributor received a call offering house valuation services and requesting personal details, despite being registered on the Do Not Call Register. The pitch appears generic, mentioning property nearby and requesting contact information to proceed.
Report Patterns and Timing
The 8 reports span from January 2025 through November 2025, with activity concentrated in the first half of the year. All reports involve answered calls or voicemails rather than missed calls, suggesting persistence in connection attempts. The silent call tactic appears in 3 reports, indicating this is a deliberate strategy rather than technical fault. One contributor described receiving multiple calls daily following the initial silent call contact.
A voicemail containing only repeated "thank you" phrases with no identifying information adds to the uncertainty about 0440136141's true origin, though the property sales context suggests real estate marketing rather than organised fraud.

WRITE A REVIEWFrequently Asked Questions
What does it mean if 04 4013 6141 calls and hangs up immediately?
Three contributors reported this pattern with 0440136141. It's commonly used as a "verification call" to confirm your number is active before sending sales pitches via a different number. One contributor described receiving a follow-up local landline call minutes later with a property sales pitch. Do not engage - simply hang up and block 04 4013 6141 if it repeats.
Is 04 4013 6141 a legitimate property inquiry?
Possibly, but unlikely. While one voicemail mentioned "Shead Property," most reports describe unsolicited contact offering valuations and requesting personal information. Contributors registered on the Do Not Call Register have received calls from 0440136141, which is illegal. If genuinely interested in a valuation, always initiate contact yourself rather than responding to cold calls from 04 4013 6141.
Can I block 04 4013 6141 on my phone?
Yes. All modern Australian phones allow you to block numbers. Add 0440136141 to your blocked list to prevent calls from 04 4013 6141 reaching you. If the number uses similar variations, your phone's settings may allow you to block numbers containing "4013 6141" patterns.
Why do contributors receive silence when answering 0440136141?
One contributor explained: 0440136141 appears to be used as a testing number to verify your phone is active, then a separate landline number calls with the actual sales pitch. This two-stage approach is designed to identify working numbers before sending costly follow-up calls. It's a common spam tactic to validate contact lists.
What should I do if 04 4013 6141 calls asking for property information?
Do not provide any details. Hang up immediately. If the caller claims to represent a specific real estate agency, contact that agency directly using their official website or published phone number to verify the inquiry. Never share personal information, property address, or contact details with unsolicited callers from 0440136141.
Is 04 4013 6141 breaking the law by calling registered numbers?
Yes. Multiple contributors reported receiving calls from 0440136141 despite being registered on Australia's Do Not Call Register. This violates the Spam Act 2003. You can lodge a formal complaint with the Australian Communications and Media Authority (ACMA) at acma.gov.au, including the date and time of the call from 04 4013 6141.
