Silent Call and Robocall Reports for 02 5350 6837

Three contributors have reported nuisance activity from 02 5350 6837 (also written as 0253506837), a NSW local number allocated to Symbio Networks. The pattern is distinctive: callers from this number appear to hang up immediately when reaching a voicemail system or when asked to leave a message. Two separate reports specifically mention automated robocall behaviour combined with instant call abandonment.

This behaviour is typical of callback scams or automated systems testing for active phone numbers. When a robocall detects voicemail or a request to record a message, it abandons the call rather than leave identifying information. The 0253506837 number shows a pattern of repeated attempts at odd hours, suggesting systematic dialling rather than legitimate contact attempts.

What Callers from 02 5350 6837 Do

One contributor reported receiving a call at 8pm with no discernible purpose, while another noted the caller "keeps calling at odd hours, instantly bails when answering machine picks up." A third contributor specifically flagged that the caller "hates answering machines" and hangs up when asked to leave a message. These responses are consistent with automated systems that prioritise live voice detection over message delivery.

The robocall nature of 02 5350 6837 is reinforced by the immediate disconnection when encountering voicemail prompts. This suggests the system is designed to generate callback lists of confirmed active numbers rather than deliver a sales pitch or scam message.

Call Patterns and Timing

Contributors report 02 5350 6837 calling at irregular times outside standard business hours, including evening periods around 8pm. One contributor specifically mentioned "odd hours" and another noted multiple call attempts, indicating repeated dialling campaigns. The abandonment pattern is consistent across reports: call connects, caller hears voicemail or message prompt, immediate disconnect without leaving information.

The frequency pattern suggests automated systems operating on a schedule rather than human decision-making about appropriate contact times.

What to Do If You Receive a Call from 02 5350 6837

If 02 5350 6837 calls you:

• Do: Let unknown calls go to voicemail, block the number if calls repeat, ignore any callback requests
• Do not: Return the call, as this confirms your number is active and may increase callback attempts
• Do not: Engage if you do answer - simply hang up immediately

Robocalls that disconnect when reaching voicemail are typically low-priority nuisance systems. Returning the call confirms your number for more aggressive campaigns later.
