In today’s communication landscape, legitimate outbound calls are often mistakenly labeled as spam, damaging brand trust and impacting connection rates. To combat this, Twilio offers a solution through Voice Integrity and SHAKEN/STIR registration, empowering businesses to maintain their reputation and ensure calls reach customers.

What Is Twilio Voice Integrity?

Twilio’s Voice Integrity is a reputation monitoring program that proactively registers your business phone numbers with major carrier analytics providers such as TNS (Verizon), First Orion (T-Mobile), and Hiya (AT&T). These services flag suspicious calling behavior and label spam—sometimes incorrectly. By registering, Twilio can help protect your numbers from false spam labels and monitor their reputations across networks.

Why Should You Care?

If your calls are being flagged as spam, they’re likely going unanswered—or worse, damaging your brand's credibility.

With Voice Integrity:

  • Your numbers are registered and monitored with the top reputation monitoring vendors.

  • You gain visibility into any reputation risks before they become costly.

  • Proactive remediation becomes possible if your number is flagged.

What Is SHAKEN/STIR?

SHAKEN/STIR is a caller ID authentication framework designed to combat spoofing.

When enabled:

  • Your outbound calls display as "Caller Verified" on supported devices.

  • Your calls receive A-level attestation, increasing customer trust and pickup rates.

Additional Resources to Help Improve Call Answer Rates

To further support successful connections, we offer a couple of tools that can increase the chances your calls are answered and captured in BrightHire:

  • Text Before Call
    Automatically send a quick message to let the candidate know you're about to call. This heads-up increases pickup rates and reduces the chance of your call being mistaken for spam.

  • Text to Call Back
    If the call goes to voicemail, follow up with a text prompting the candidate to return your call. When they do, the conversation will still be recorded and captured in BrightHire.
