Silent Call and Robocall Reports for 03 6159 9499

Five contributors have reported suspicious activity from 03 6159 9499 (also written as 0361599499), with a distinct pattern of silent calls and robocall behaviour. The calls are allocated to Symbio Networks, a local service provider in Tasmania. Multiple reports describe the caller establishing connection, then remaining silent or cutting off abruptly before any conversation begins.

Contributors receiving calls from 0361599499 note varying tactics: some experience immediate silence followed by disconnection, while others report brief audio before the line drops. One contributor observed the caller attempting multiple numbers in the same 03 6159 94 range, suggesting systematic dialling patterns rather than random contact.

What Callers from 03 6159 9499 Do

The silent call pattern is consistent across reports of 03 6159 9499. One contributor answered and experienced silence for several seconds before a woman's voice briefly came through, then disconnected. Another described a similar sequence: dead air, then a voice attempting to engage before the call ended abruptly.

A contributor who received a voicemail from 0361599499 reported 30 seconds of heavy breathing with random background noises, then disconnection. This voicemail behaviour, combined with the silent call pattern, suggests automated systems testing line connectivity or attempting to verify active numbers.

One contributor who called back the number received a disconnection message from Optus, indicating the number may not accept return calls. The caller's apparent connection to a call centre environment (noted as sounding like an Indian call centre operation) combined with the systematic dialling of similar 03 6159 94 numbers raises concerns about coordinated contact attempts.

Call Patterns and Behaviour

Reports of 03 6159 9499 show activity spanning from August through November 2025, with missed calls, answered calls, and voicemail contact recorded. The reports cluster around two distinct patterns: brief answered calls with silence or hang-ups, and missed calls generating no connection opportunity.

One contributor received missed calls for two consecutive days from 0361599499 before attempting to return the call. The inability to reach the number through standard callback suggests the calls originate from automated systems rather than a standard phone line. Multiple contributors noted the calls consistently disconnected before or immediately after they picked up, preventing any actual conversation.
