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

Requirements Before You Start

To use Voice Integrity, you’ll need the following:

• SHAKEN/STIR Certification (Required)
  This protocol verifies that your call is authentic and hasn’t been spoofed.

• CNAM (Recommended)
  A branded caller name (like your business name) further improves trust.

• US Phone Numbers Only
  This feature only applies to U.S.-based traffic. International numbers are currently not supported.

What Happens After You Register?

Once you submit your information, each of the analytics providers—Hiya, TNS, and First Orion—will review your registration separately.

• Expect to receive confirmation emails within 2 business days

• Label removal may take time to propagate across all networks

• Contact the analytics providers directly if you don’t receive a response:

  1. First Orion: [email protected]

  2. Hiya: [email protected]

  3. TNS: [email protected]

Note-To get started with Voice Integrity, your business must first be registered for SHAKEN/STIR, which requires a valid Employer Identification Number (EIN). However, if you’re a sole proprietor or do not yet have an EIN, you can still improve your phone number reputation using the Free Caller Registry.

What is the Free Caller Registry?

The Free Caller Registry is a centralized platform that allows businesses to submit their phone numbers for review by the three major U.S. providers. These providers determine how your calls are labeled on recipients’ devices. Registering your numbers helps establish your legitimacy and reduce the chances of your calls being marked as “Spam Likely.” The Free Caller Registry is specifically designed for use within the United States and is intended to support U.S. domestic phone numbers.

Frequently Asked Questions

Q: How long does registration take?
Usually 3–7 business days. Each provider works independently, so timing may vary.

Q: What if I don’t get a confirmation?
Check your spam/junk folders. If still missing after a week, contact the analytics provider directly.

Q: Will registration guarantee that my number won’t be marked as spam?
Not guaranteed, but it significantly reduces the risk. Consistent and responsible call behavior is also important.

Q: Can I register VoIP or toll-free numbers?
Yes, just ensure the service provider is accurately listed.

Q: Do I need to update my registration?
Yes, if your call patterns or numbers change significantly.

Q: Does this affect SMS spam labels too?
No. This registry only affects voice calls. For SMS, ensure you’re registered under A2P 10DLC compliance.
