Nuisance Call Reports for 02 9159 9831
A single contributor has reported receiving a call from 02 9159 9831 (also written as 0291599831) that left a puzzling voicemail. The call came through to a NSW local service number allocated to Symbio Networks Pty Ltd, but the message left behind consisted only of indistinct mechanical noise with no intelligible content or clear purpose.
The contributor received both a call and an SMS notification indicating a voicemail had been left, but when they retrieved the message from 02 9159 9831, it proved entirely useless. The nature of the noise and the deliberate notification suggest this may be an automated system test, a network issue, or potentially a nuisance caller using mechanical sounds to probe active numbers.
Call Details and Timing
The call from 02 9159 9831 arrived at 1:14 PM, during business hours. The contributor noted the call was anomalous enough to warrant blocking the number, indicating the experience was frustrating or unsettling rather than a standard misdial or network glitch.
The use of both a voice call and SMS notification to alert about the voicemail suggests this may originate from an automated system rather than a human caller, though the purpose remains unclear. Whether 0291599831 is being used intentionally for nuisance purposes or represents a misconfiguration on the provider's network is difficult to determine from a single report.

What Our Users Reviewed
Got a call from this number earlier today (1:14 PM) and an SMS indicating a message had been left. When I listened to the message later, it turned out to be just a short, indistinct mechanical noise. It was of no use whatsoever.
Not just your usual timewaster, but one with a dark sense of humour as well perhaps. Definitely a number to block.

A contributor received a call from 02 9159 9831 (0291599831) with a voicemail containing only indistinct mechanical noise.
