## Linear ticket
https://linear.app/chatwoot/issue/CW-7187/voice-calls-followup-tasks
## Description
Improvements to the WhatsApp voice-calling experience plus a cheaper,
more accurate audio-transcription model.
- First-time callers now get a real name. An inbound WhatsApp call
creates the contact from the caller's WhatsApp profile name instead of
the bare phone number.
- Clear, consistent call attribution. Call bubbles show a unified
"Handled by {agent}"
- Cleaner call widget. The dismiss (✕) button is shown only for incoming
calls
- WhatsApp calling for manual inboxes. voice_calling_supported? now
covers any whatsapp_cloud inbox
- Transcription: whisper-1 → gpt-4o-mini-transcribe.

## Summary
Frontend for WhatsApp Cloud Calling: header / contact-panel call
buttons, ringing widget, accept/reject/hangup, mute, in-bubble audio
player + transcript, recording-on-hangup upload, mid-call reload
warning. WebRTC is browser-direct to Meta — no media server bridge.
## Closes
- https://linear.app/chatwoot/issue/PLA-150
## How to test
Requires backend support — the controller, services, model changes, and
routes ship in **#14334** (`feature/pla-150`). Merge / deploy that first
(or simultaneously); the FE alone won't function without those
endpoints.
Then on staging, for a WhatsApp Cloud + embedded-signup inbox with the
new \`Configuration → Enable voice calling\` toggle ON and webhook
registered:
1. **Outbound** — open a conversation, click the phone icon in the
conversation header (or contact panel), grant mic, your phone rings,
answer, audio both ways, hang up. Recording + transcript land in the
bubble within ~10s.
2. **Inbound** — call the business number from your phone. The
FloatingCallWidget appears bottom-right with caller name. Click accept,
audio both ways, hang up. Recording + transcript appear.
3. **Mute** — during an active WhatsApp call, click the mic icon next to
hangup. Speech stops reaching Meta until you click again.
4. **Mid-call reload guard** — try `Cmd-R` during an active call;
browser shows a confirm prompt.

Adds the server-side flow that turns Meta WhatsApp Cloud Calling
webhooks into Chatwoot Calls, conversations, voice_call message bubbles,
and ActionCable broadcasts. Stacked on top of #14312 (PR-2 — provider
methods); intentionally does not include the HTTP controller, routes, or
frontend (those land in PR-4 and PR-9).
## Closes
- Part of the WhatsApp Cloud Calling rollout. Linear: TBD
## What changed
**Webhook routing**
- `app/jobs/webhooks/whatsapp_events_job.rb` — append
`prepend_mod_with('Webhooks::WhatsappEventsJob')` so EE can extend it
without forking.
- `enterprise/app/jobs/enterprise/webhooks/whatsapp_events_job.rb` (new)
— overlay that prepends `handle_message_events` to intercept `field:
'calls'` payloads (route to `Whatsapp::IncomingCallService`) and
`interactive.call_permission_reply` messages (route to
`Whatsapp::CallPermissionReplyService`); falls through with `super` for
regular messages.
**Services**
- `enterprise/app/services/whatsapp/incoming_call_service.rb` (new) —
gated on `provider_config['calling_enabled']`; processes `connect`
(creates inbound call via `Voice::InboundCallBuilder` or transitions an
existing outbound call to `in_progress`) and `terminate` events; updates
conversation `additional_attributes` and broadcasts
`voice_call.incoming`/`voice_call.outbound_connected`/`voice_call.ended`.
- `enterprise/app/services/whatsapp/call_permission_reply_service.rb`
(new) — handles WhatsApp interactive `call_permission_reply` replies;
clears the conversation's `call_permission_requested_at` flag and
broadcasts `voice_call.permission_granted` so the agent UI can re-enable
the call button.
**Builder/model adjustments**
- `enterprise/app/services/voice/inbound_call_builder.rb` —
provider-agnostic; accepts `provider:` and `extra_meta:` kwargs, drops
`account:` (now derived from `inbox.account` to keep the param count
under rubocop's ceiling without disabling cops), uses digits-only
`source_id` for WhatsApp ContactInbox (validation requires
`^\d{1,15}\z`), skips Twilio-only `conference_sid` for non-Twilio
providers.
- `enterprise/app/services/voice/call_message_builder.rb` — adds
`create!`/`update_status!` API and `CALL_TO_VOICE_STATUS` map; uses
direct `Message.create!` (bypasses `Messages::MessageBuilder`'s
incoming-on-non-Api-inbox guard, which would otherwise reject the system
bubble); content is `'WhatsApp Call'` for WhatsApp and `'Voice Call'`
for Twilio. Backwards-compatible `perform!` retained for the existing
Twilio call sites.
- `enterprise/app/models/call.rb` — adds `default_ice_servers` (driven
by `VOICE_CALL_STUN_URLS` env), `direction_label` alias for the
`inbound`/`outbound` strings the FE expects, and
`ringing?`/`in_progress?`/`terminal?` predicates used throughout the
pipeline.
**Outgoing-channel guard**
- `app/services/base/send_on_channel_service.rb` — extends
`invalid_message?` to skip messages with `content_type == 'voice_call'`.
Without this, agent-initiated outbound calls (PR-4) would deliver
\"WhatsApp Call\" as a text message to the contact every time.
**Twilio call-site update**
- `enterprise/app/controllers/twilio/voice_controller.rb` — drops the
now-redundant `account: current_account` kwarg from the
`Voice::InboundCallBuilder.perform!` call.
**Tests**
- New: `spec/enterprise/services/whatsapp/incoming_call_service_spec.rb`
(5 examples — calling-disabled, inbound connect, outbound connect,
terminate completed, terminate no-answer, unknown event).
- New:
`spec/enterprise/services/whatsapp/call_permission_reply_service_spec.rb`
(3 examples — accept, reject, calling-disabled).
- Updated: `spec/enterprise/services/voice/inbound_call_builder_spec.rb`
and `spec/enterprise/controllers/twilio/voice_controller_spec.rb` to
drop the `account:` kwarg from call expectations.
## How to test
In `rails console` against an account with a WhatsApp inbox where
`provider_config['calling_enabled']` is true:
```ruby
inbox = Inbox.find(<id>)
params = { calls: [{ id: 'wacid_test', from: '15550001111', event: 'connect',
session: { sdp: 'v=0...', sdp_type: 'offer' } }] }
Whatsapp::IncomingCallService.new(inbox: inbox, params: params).perform
# => Conversation + Call (status: 'ringing', provider: 'whatsapp') + voice_call message bubble
# => ActionCable broadcasts `voice_call.incoming` to the assignee or account-wide
# Then terminate it:
Whatsapp::IncomingCallService.new(inbox: inbox,
params: { calls: [{ id: 'wacid_test', event: 'terminate', duration: 0, terminate_reason: 'no_answer' }] }
).perform
# => Call status flips to 'no_answer', message bubble updates, `voice_call.ended` broadcast fires
```
End-to-end browser flow (Meta → cable → UI) requires the controller from
PR-4 and the frontend from PR-9.

Twilio voice now uses first-class `Call` records as the source of truth
for call state, instead of storing it on
`conversation.additional_attributes` and `conversation.identifier`. Each
call gets its own record, its own `voice_call` bubble matched by
`call_sid`, and its own conference name keyed off `Call.id`. Multiple
calls on the same conversation (for `lock_to_single_conversation`
inboxes) now work correctly, and the conversation card stays in sync
with the real latest message.

This PR delivers the first slice of the voice channel: inbound call
handling. When a customer calls a configured voice
number, Chatwoot now creates a new conversation and shows a dedicated
call bubble in the UI. As the call progresses
(ringing, answered, completed), its status updates in real time in both
the conversation list and the call bubble, so
agents can instantly see what’s happening. This focuses on the inbound
flow and is part of breaking the larger voice
feature into smaller, functional, and testable units; further
enhancements will follow in subsequent PRs.

## Testing
- Configure a Voice inbox in Chatwoot with your Twilio number.
- Place a call to that number.
- Verify a new conversation appears in the Voice inbox for the call.
- Open it and confirm a dedicated voice call message bubble is shown.
- Watch status update live (ringing/answered); hang up and see it change
to completed in both the bubble and conversation
list.
- to test missed call status, make sure to hangup the call before the
please wait while we connect you to an agent message plays
