Silent Calls and Spam from 02 5350 6864

Four contributors have reported calls from 02 5350 6864 (also written as 0253506864), a local service number registered in NSW. The primary pattern involves silent calls where the line connects but no one speaks, alongside unsolicited calls from call centres and charity fundraising organisations. One contributor received a silent call from 02 5350 6864 that prompted them to block the number immediately, while others experienced typical call centre activity.

The number is allocated to Symbio Networks Pty Ltd as a local NSW service, but the reported behaviour suggests it may be misused for unwanted outbound calling activity. Contributors describe the silent calls as particularly frustrating, with the line ringing through but disconnecting without any message or purpose.

What Callers from 02 5350 6864 Do

Reports about 0253506864 describe two distinct patterns. The silent call tactic involves the number connecting and then going quiet with no explanation or voicemail left behind. One contributor noted that when they answered, there was simply silence on the line. This behaviour is consistent with callback scams or testing active phone numbers for targeting.

When the line is not silent, callers from 02 5350 6864 identify themselves as representatives of fundraising or charity organisations. One contributor who called back found this to be the case, though they chose to block the number. Other reports mention general call centre activity without specific claims or sales pitches, suggesting the number may be used for outbound dialling campaigns by multiple organisations or contractors.

Report Patterns and Timing

The four reports span from July 2025 to January 2026, indicating ongoing activity from 02 5350 6864. One silent call was logged during business hours (around 9 AM), while others came in during mid-morning and early morning slots. Contributors have consistently chosen to block the number rather than engage further, suggesting the repeated or unwanted nature of contact. The mix of silent calls, charity pitches, and generic call centre activity suggests the number may be shared across different campaign operators or used for testing.
