Use a voice AI agent to replace slow IVR authentication with a natural verification flow connected to your identity systems. Start building in Mission Control with usage-based pricing. introduction ## What this voice AI agent does Build a voice AI agent that authenticates callers quickly and securely with Telnyx. The agent replaces traditional IVR authentication flows where customers enter account numbers and answer security questions with a natural conversation that verifies identity using multi-factor checks, account data lookups, and configurable security policies. The authentication agent works across high-trust industries. Banks can verify account holders before transferring to advisors, healthcare providers can confirm patient identity before sharing records, and ecommerce teams can validate customers before processing high-value changes. The workflow can connect to your identity provider, CRM, or account system to perform real-time verification and log authentication attempts for review. There is no exact pre-configured Mission Control authentication template yet. The Multi-Department Router template is a related routing layer you can combine with authentication logic, but the authentication workflow itself should be built as a custom voice AI agent. **features** ## Core components of the customer authentication agent ### Identity verification flow Collect caller identifiers, confirm ownership, and validate one-time passcodes or account signals before protected information is shared. ### System lookup and OTP validation Connect to your CRM, identity provider, or account database so the agent can verify details and validate one-time passcodes in real time. ### Secure routing and audit trail Route verified callers to the right team with context, block unverified callers from protected workflows, and log outcomes for compliance review. how to ## Build and deploy your agent in 5 easy steps Use this workflow to build a custom authentication agent in Mission Control. **time** 5-7 minutes **pre-requisites** A Telnyx account, a phone number, a Voice AI Agent, and access to your identity or account system. **Step 1 of 5** ### 1. Create the agent in Mission Control Open Mission Control, go to AI Assistants, and create a new voice AI agent from Blank. ### 2. Add authentication instructions Define what the agent can ask for, what it must verify, and what information it must never disclose before verification. ### 3. Connect verification tools Add webhook tools for sending one-time codes, validating codes, and looking up caller records in your identity system. ### 4. Choose voice and transcription Select the voice provider, voice, and transcription model that fit your caller experience. ### 5. Assign a phone number and test Assign a Telnyx number, run test calls with successful and failed verification paths, and confirm the agent transfers only after verification. **tips and insights** ## Voice AI authentication best practices ### Use step-up checks for riskier calls Require stronger verification before account changes, financial details, protected health information, or high-value transactions. Require stronger verification before account changes, financial details, protected health information, or high-value transactions. ### Keep failure handling short If verification fails twice, stop the protected flow and route to a person or ask the caller to try again later. If verification fails twice, stop the protected flow and route to a person or ask the caller to try again later. ### Confirm sensitive digits clearly When confirming phone numbers, account numbers, or one-time codes, have the agent read digits in small groups and confirm accuracy.
