Route an inbound SIP trunk to OpenAI Realtime, verify incoming-call webhooks, disclose AI processing and obtain explicit consent before transcript or CRM use, operate a server-side sideband channel for bounded read-only tools, support natural interruption, transfer confirmed calls to allowlisted human queues, create reviewable call summaries, and require a named human before any CRM summary write.
