Call Authentication

Call Authentication spoof-proofs your outbound calling numbers. This end-to-end secure feature is included in the delivery of our INFORM with Logo and SENTRY Call Blocking, ensuring your customized display appears only on verified calls and/or unverified calls are blocked from reaching the end user

Benefits

Vetted Businesses Only Platform – Businesses are vetted by First Orion before branding or blocking is enabled
End-To-End Call Authentication - Prior to the call "originating" enterprises "signal" to First Orion. Branding is then "set" in network for finite amount of time by First Orion. The terminated phone call that passes end-to-end check will be "authenticated" and branded or spoofed accordingly.
Consistent Attestation Level - Successful, authenticated phone calls terminate with "A-Level" attestation. Enterprises unlikely to become OSP for enterprise-level Stir/Shaken. (Some calling platforms obfuscate originating carrier resulting in inconsistent attestation levels)

Treatment of the authenticated call is dependent on the purchased service of INFORM with Call Authentication, INFORM with Logo or SENTRY Call Blocking and the creation of a calling program.
