Silent Calls and Spam from 0403 781 385
Six contributors have reported activity from 0403 781 385 (also written as 0403781385), a mobile number on the Optus network. The pattern shows a mix of silent calls, spam contact, and suspicious behaviour. One contributor specifically identified the caller as associated with IT Hero, a known spam operation. Others reported receiving calls that either went unanswered, left no message, or couldn't be returned, suggesting either automated calling or unwillingness to engage when contacted back.
The inconsistency in caller behaviour is notable. One contributor answered and spoke to someone named Jenny who provided no information about her organisation when asked, raising immediate red flags. Other contributors experienced the more typical spam pattern of missed calls with no voicemail, making it impossible to determine the caller's intent or legitimacy.
What Callers from 0403 781 385 Say
When 0403 781 385 reaches someone who answers, the interaction varies. One contributor reported a caller named Jenny who identified herself to Siri but refused to provide organisational affiliation or purpose for the call. This evasive behaviour is a common tactic used by spam and scam operations attempting to bypass screening.
Most calls from 0403781385 follow the silent call pattern, where the line connects but the caller either hangs up immediately or remains silent. Contributors who attempted to call back reported that the number would not accept incoming calls, confirming the one-way nature of the contact attempt.
Report Patterns and Timing
The six reports span from August 2025 to January 2026, showing persistent activity over several months. One contributor noted a call arriving at 9:15 am with no follow-up. Contributors received calls across different channels, including both answered calls and missed calls, suggesting either dialling from multiple attempts or involvement of automated systems.
Three separate reports specifically mention the caller leaving no voicemail message, which is consistent with robocall or auto-dialler behaviour rather than legitimate business contact. The contributor who received the call from Jenny noted the call came through despite not being in any obvious contact list, and the refusal to provide caller details strengthened the suspicion it was spam.

WRITE A REVIEWFrequently Asked Questions
Is 0403 781 385 a legitimate business number?
Based on community reports, 0403 781 385 (0403781385) appears to be associated with spam activity. One contributor identified it as linked to IT Hero, a known spam operation. The pattern of silent calls and refusal to identify the organisation suggests this is not a legitimate business contact. Block the number and avoid returning any calls.
Why do calls from 0403781385 leave no voicemail message?
Several contributors reported that 0403 781 385 left no voicemail despite ringing through. This is typical of automated spam or silent call systems, which may be testing whether a number is active rather than attempting genuine contact. These systems often don't leave messages because the goal is lead generation or validation, not communication.
What should I do if 0403 781 385 calls me back after I call the number?
Contributors who called back 0403781385 found the number would not accept incoming calls, which is a strong indicator of spam. If you're considering calling back to confirm, this is likely unnecessary and could add your number to an active list. Instead, block 0403 781 385 on your Optus mobile and report it to ACMA.
Can I block 0403 781 385 on my Optus mobile?
Yes. Since 0403781385 is a mobile number on the Optus network, you can block it directly through your phone's call filtering settings. You can also contact Optus customer service to request they block the number at the network level to prevent the calls reaching you.
Why did the caller from 0403 781 385 refuse to say which organisation they were from?
One contributor reported that a caller named Jenny identified herself to Siri but refused to disclose her organisation. This refusal is a red flag for spam and scam operations, which often avoid stating their affiliation because they're engaged in unauthorised marketing or are attempting a scam. Legitimate businesses always identify their organisation upfront.

Six contributors have reported activity from 0403 781 385 (0403781385) on Reverseau, with reports spanning from August 2025 to January 2026.
