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

Comment Received Trigger

Triggered when a comment is received.

Action

Get Phone Number Information

Tool to retrieve detailed information about a specific phone number, including reputation, business and carrier details, and ftc complaints. use when the number is in e.164 format and set hlr=true to include hlr data (adds 1-3 seconds to response).

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

Build it in a few focused steps.

  • 1Integrate Linear and Callerapi with Notis (one-time setup)
  • 2Create an automation: 'When a comment is received that mentions a phone number, get phone number reputation from Callerapi'
  • 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.
