What Is a STIR/SHAKEN App?
A STIR/SHAKEN app is a cloud-based solution that digitally verifies your outbound caller ID to prevent spoofing and unauthorized number use. It works by attaching a secure digital signature to each outgoing call, confirming your business identity before the call even connects.
With CloudTalk’s STIR/SHAKEN app, your outbound calls are trusted, verified, and far less likely to be flagged as spam, boosting answer rates and protecting your brand.

How Does STIR/SHAKEN Work?
Every time you place a call, CloudTalk’s STIR/SHAKEN verification app digitally signs your outbound caller ID using an encrypted certificate. The recipient’s carrier then verifies this signature, confirming the call’s authenticity and ensuring it hasn’t been spoofed.
Legitimate, verified calls get delivered smoothly, while spoofed or unverified numbers are filtered out—protecting customers and strengthening your outreach.

Where Can You Use a STIR/SHAKEN App?
- Outbound Business Calls: Ensure your outbound sales, service, and notification calls aren’t flagged as spam. Verified numbers improve pick-up rates and customer trust.
- Call Centers: Verify your identity on every call, giving customers confidence they’re speaking with a legitimate call center business. Reduce manual ID checks and streamline call handling.
- VoIP and Telecom Providers: Protect your network from spoofed calls. STIR/SHAKEN verification secures outbound traffic, reduces fraud, and improves service quality.
- High-Risk Industries: Guarantee sensitive, urgent calls get through without being blocked in healthcare and finance industries. Verified numbers help protect private information and ensure critical updates are delivered securely and reliably.
