Preventing Zoom Phone Calls from Being Marked as Spam
To ensure your Zoom Phone calls are received reliably, it’s important to understand how spam filters work and what steps you can take to avoid being flagged.
Why Do Some Calls Get Labeled as “Spam Likely”?
Phone carriers and analytics systems flag calls based on:
- High volume of short or repetitive calls
- Incomplete or inconsistent caller ID
- Numbers not registered with reputation services
- Negative recipient feedback (people marking calls as spam)
What You Can Do
1. Use a Recognizable Caller ID (CNAM)
Ensure your outgoing caller ID shows your department or Andrews University clearly.
Example: “AU Registrar” or “Andrews Univ”
If your Caller ID appears blank or confusing, recipients are more likely to ignore or block your call.
2. Avoid Spam-Like Call Patterns
- Don’t repeatedly call the same number in short timeframes
- Avoid excessive short-duration calls (under 30 seconds)
- Make calls during standard business hours when possible
3. Encourage Recipients to Save Your Number
Tell students, faculty, or external contacts to save your office number in their phones. This improves trust and helps bypass spam filters.
4. Report Call Labeling Issues
If your calls are marked as spam:
- Submit a request through Zoom Support (https://support.zoom.us/)
- Or email ITS Telecom Services at [Insert AU contact email here] with:
• Your phone number
• A brief explanation of the issue
• Screenshots (if possible)
