# rlm_axiom_025

**principle**: Async webhook pattern prevents voice AI freeze: CRM lookups that take >2 seconds will freeze the AI during a call. Always configure Telnyx tool webhooks as async (request_mode: async). AI keeps talking while data fetches in background, then injects result.

**evidence**: Telnyx async webhook axiom from telnyx_mastery.jsonl. Live call experience: AI assistant must keep speaking while GHL CRM lookup happens. 2+ second silence = terrible UX. Async mode = seamless.

**strength**: high
