02 4216 8901 (0242168901): 2 reports of suspicious calls including robocall activity and impersonation of a national security company.

Suspicious Activity Reports for 02 4216 8901

Two contributors have reported suspicious calls from 02 4216 8901 (also written as 0242168901), a local NSW number allocated to Symbio Networks. The reports describe two distinct types of problematic activity: robocall behaviour and impersonation tactics.

The first report documents a call where the contributor heard call centre background noise followed by silence before the line dropped. This pattern is typical of automated dialling systems testing for active numbers. The contributor blocked the number and reported it immediately. A second report from May 2025 describes a caller claiming affiliation with a national security company, a common impersonation tactic used to establish false credibility and lower a recipient's defences.

What Callers from 02 4216 8901 Have Claimed

One contributor received a call where the person claimed to represent a national security company. This type of impersonation is designed to create urgency and authority, making it harder for recipients to question requests or hang up. The use of security-related authority is particularly effective because it implies legal backing or official oversight.

The robocall report from 02 4216 8901 reveals another concerning pattern: automated systems are contacting this number, which suggests it may be part of a larger calling campaign. When you hear call centre noise and then silence after answering, it typically indicates an automated dialler has connected you but no operator is immediately available.

Report Patterns and Timing

The two reports span several months, with the impersonation call occurring in May 2025 and the robocall activity documented in November 2025. The robocall report describes immediate blocking and reporting by the contributor, which is the appropriate response to this type of activity.

Both reports originated from answered calls, meaning the contributors actually engaged with the caller or dialling system before recognising the suspicious behaviour. This suggests the number may be actively used in calling campaigns rather than being dormant.
