Overview

In this article, we will learn how we can increase our call answer rates by remediating 'spam likely' / 'potential spam' / 'scam likely' on the caller ID in the US (US only).

If the phone number flagged as 'spam likely' is relatively new or not critical to your business or has a FTC complaint, we recommend trashing the phone number and getting a new one. It's faster, easier and more convenient for you as compared to remediating the 'spam likely' tag.

If you have an EIN and your number is flagged as ‘Spam Likely’, we recommend registering through Voice Integrity, available in the HighLevel portal. For full steps, see our article: Why are my Calls marked as Spam, and How can I avoid it ?

If you don’t have an EIN, we suggest registering your number with the Free call registry instead.

What is Voice Integrity?

Voice Integrity is a game-changing feature that helps protect your business calls from being flagged as “Spam Likely.” By registering your U.S.-based phone numbers with top caller ID analytics providers—First Orion, Hiya, and TNS—you can improve pickup rates and reinforce your brand’s trustworthiness.

Why Turn On Voice Integrity?

If your business numbers are flagged or blocked, Voice Integrity helps you:

• Fix bad reputations and clear “Spam Likely” labels from legitimate calls.

• Increase pickup rates—recipients are more likely to answer when your caller ID shows a verified, trusted name.

• Ensure your calls are seen as authentic, not suspicious.

• Boost call answer rates with a verified and trusted caller ID

• Help prevent your numbers from being blocked or ignored

• Maintain a positive caller reputation over time

• Establish trust and credibility with recipients

• Support consistent branding through accurate caller ID display

What You Need to Get Started

Before activating Voice Integrity, ensure you meet these requirements:

• SHAKEN/STIR Certification (Required):
  Confirms your calls are legitimate and not spoofed.

• CNAM Registration (Recommended):
  Displays your business name as the caller ID, increasing credibility.

• U.S. Phone Numbers Only:
  Currently, Voice Integrity applies only to U.S.-based numbers. International traffic is not supported.
  
  

Note- An EIN (Employer Identification Number) is required to complete SHAKEN/STIR registration. If you don’t have an EIN, we recommend registering your number with the Free call registry instead.
