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.

- Add dynamic importing for routes.
- Added caching for `campaign`, `articles` and `inbox_members` API end
points.

In this PR https://github.com/chatwoot/chatwoot/pull/11139, if there is
an attempt to create a duplication session for the contact in the same
inbox, we will anonymize the old session.
This PR would prevent sending messages to the older sessions. The
support agents will have to create a new conversation to continue
messages with customer.
