Verify Phone Numbers in Comments Before Calling
Your team mentions callback numbers in comments. Notis instantly checks if they're spam so no one wastes time on bad calls.
Trigger

Why this helps
Team members comment with a phone number to call back, but there's no quick way to verify if it's spam before the call is made
- Catch spam numbers before callbacks
- Prevent team from calling bad numbers
- Reduce wasted call attempts
- Protect team security
Setup

- 3Set the trigger to 'Comment Received' and route notifications to your team channel
- 4Notis will now scan each comment for phone numbers and validate them automatically
- 5Try adding a test callback number in a comment to see the spam/reputation check appear
Questions about this workflow
Do I need to format the phone number specially?
No. Notis looks for phone numbers in standard formats. Just mention the number naturally in the comment.
What if the number is a false positive?
Notis returns reputation data including carrier and business details. You can make the judgment call safely.
Can this work in private team comments?
Yes. Use the 'Private Team Comment Created' trigger for the same automation in private Linear teams.
