Wires Meta's WhatsApp Cloud Calling APIs into the voice subsystem so agents can answer / place calls on WhatsApp Cloud inboxes from the existing Voice flow. Browser ↔ Meta WebRTC is direct (no media-server hop); Chatwoot owns the signalling, recording upload, and lifecycle state on the Call/Message records. Backend - API surface: new Api::V1::Accounts::WhatsappCallsController with show / accept / reject / terminate / initiate / upload_recording. Enforces conversation-level Pundit visibility, blocks initiate when the channel isn't embedded-signup voice-enabled, and surfaces the Meta 138006 (no-call-permission) flow as a throttled opt-in template send under a conversation lock so concurrent retries can't double-send. - Whatsapp::CallService — accept/reject/terminate state machine with call-level locking; wraps Meta API failures (transport or business) as Voice::CallErrors::CallFailed so the controller renders 422. - Whatsapp::IncomingCallService — handles Meta connect/terminate webhooks; pins setup:active on outbound answers, materialises a missed-call record when terminate arrives before connect, and broadcasts voice_call.* events to assignee or account streams. - Whatsapp::Providers::WhatsappCloudService — adds pre_accept/accept/ reject/terminate/initiate/permission-request endpoints. Uses configurable WHATSAPP_API_VERSION (default v22) since the Calls API needs v17+ and OSS phone_id_path is locked at v13. - Audio recordings: Attachment after_create_commit enqueues transcription and rebroadcasts the message so the FE bubble updates immediately. Active Storage initializer allows audio MIME types to serve inline. Audio transcription drops Whisper temperature to 0 to suppress hallucinations on silence. - Channel::Voice stub backs legacy inbox rows whose channel_type survived the DropChannelVoice migration so jbuilder .try chains short-circuit instead of raising. Routes / config - /api/v1/accounts/:id/whatsapp_calls/* (enterprise-only) - en.yml error strings under errors.whatsapp.calls.* The FE consumer of this API ships separately on feat/whatsapp-call-ui.
