How to Improve Phone Number Reputation with Voice Integrity

Voice Integrity registers your US phone numbers with the three caller-ID analytics networks – First Orion, Hiya, and TNS – to remove spam labels and rebuild answer rates on flagged numbers.

Why register

• Clear spam flags. Direct registration with the analytics networks lets you challenge existing "spam likely" labels.
• Higher answer rates. Calls displaying a recognized branded name pick up far more often than unlabeled calls.
• Better deliverability. Legitimate calls avoid blocks at the carrier and handset level.

Sparkforge may prompt you to register after an unanswered outbound call from the web dialer. The prompt is a shortcut to the same registration form covered below.

Before you register

• SHAKEN/STIR registration is required. Voice Integrity needs valid attestation on every outgoing call. Complete SHAKEN/STIR first.
• CNAM is recommended. Submitting a branded caller name alongside the number increases trust scoring.
• US numbers only. International numbers cannot register through Voice Integrity today.

Enable Voice Integrity

1. Open the Trust Center in your Sparkforge account.
2. Go to the Voice Integrity tab.
3. Fill in the registration form:
   • Use Case – sales outreach, customer support, or whatever fits.
   • Employee Count.
   • Average Business Day Call Volume.
   • CNAM Details – optional branded name.
4. Click Submit.

Track the application from the Submitted Applications tab in the Trust Center.

What happens after submission

Each analytics network reviews the registration on its own.

• Most applications clear in two business days.
• You receive a notification once a network approves.
• Label removal can take additional time to propagate across carriers and handsets.

If you do not have an EIN

SHAKEN/STIR registration requires an EIN. Sole proprietors without an EIN can still improve reputation through the Free Caller Registry as an interim option.
