Robocall and Silent Call Reports for 07 3543 5247

Two contributors have reported calls from 07 3543 5247 (also written as 0735435247), a Brisbane-based local number allocated to NetSIP Pty Ltd. Both reports describe the same distinctive pattern: silence lasting a few seconds, followed by an automated voice message saying "Goodbye" before disconnecting. This behaviour is characteristic of robocall systems, often used to identify active phone numbers or test call completion rates.

The repeated identical script across both reports suggests an automated dialling system rather than a live operator. Contributors flagged 0735435247 as suspicious and unusual due to the abrupt automated farewell with no actual communication attempt.

What Callers from 07 3543 5247 Do

When answering calls from 07 3543 5247, contributors experienced an initial silence lasting several seconds. This pause is typical of automated dialling systems waiting for voice recognition or connection confirmation. After the silence, an automated voice immediately states "Goodbye" and terminates the call without any greeting, message, or opportunity for interaction.

This pattern differs from standard telemarketing or scam calls that attempt to engage the recipient. Instead, the caller from 0735435247 appears to be testing whether the number is active and monitored, a common reconnaissance tactic used by scammers, spam operators, or data brokers to validate contact lists for later exploitation.

Report Patterns and Timing

Both calls to 07 3543 5247 were answered by the recipients, occurring within a 7-hour window on 20 January 2026. The first call came through at 12:18 AM, followed by another at 7:35 AM. The rapid reoccurrence suggests the robocall system may be cycling through contact lists or confirming number validity across multiple time slots.

Reports indicate these were inbound calls rather than voicemails or missed calls, meaning the robocall system successfully connected to an active line both times. The fact that contributors chose to answer and documented the behaviour suggests recognition that this type of call pattern warrants caution.
