Browser Calls could miss trickled candidates, burst requests after a call, and show camera capture as shared before the phone acknowledged video. This draft binds signaling and media controls to the active connection and makes local/remote video state explicit. It adds group origination and re-ring, emoji reactions, raised hands, scoped call records and a picker among separately authorized outgoing Number clients. Incoming phone video is accepted without turning on the browser camera.

The TypeScript SDK now also exposes server-only WhatsApp call-link create/preview. Client tokens are refused, link tokens stay in explicit request/response fields, and ambiguous writes are not retried. The contract snapshots are byte-identical to merged API commit 5f6a2b1 recorded in contracts/source.json; strict coverage reports 519 operations, 387 covered, 132 intentional exclusions and no drift; the newly merged media download and campaign update operations remain owned by SDK PRs 316 and 307. SDK build, typecheck, format, strict coverage and full Node 20/22 suites (1,371 tests each) passed locally.

Six-part scope: API authority and OpenAPI are in API PR 337; SDK methods, browser and UI controls are updated here; CLI PR 44 keeps its older published SDK pin and refuses unavailable controls before transport; Calls/SDK guides and release records are updated without a shipped announcement; the existing Calls entitlement and operational disable still govern server access; existing Admin calling, SIP and retention controls suffice because this SDK adds no staff setting.

Source merge is gated by exact-head CI and review. SDK publication, CLI exact registry pin, deployment and real two-Number, phone-video, group and social-control acceptance are separate gates. Call-link join/approval, SIP H.264 video and orientation safety remain open. Call transfer was deferred by the owner.

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

This change adds group-call placement, participant ringing, media controls, social controls, and screen sharing. Browser Calls uses lifecycle-socket ICE candidate exchange with HTTP polling after disconnection. Final quality reports follow the five-second interval. The Calls example supports multiple authorized Numbers and displays call errors and failed-request details.

Changes

Calls APIs and browser calling

Layer / File(s) Summary
Call placement and interaction APIs
contracts/openapi.messaging.json, packages/calls/src/*, packages/typescript/src/messaging/*, packages/browser/src/calls/*
The APIs support participant-list and stored-group placement, participant ringing, reactions, and hand-state updates. Call placement validates destination forms and group identifiers.
Acknowledged media and social controls
packages/calls/src/media-state.ts, packages/calls/src/protocol.ts, packages/calls/src/media.ts, packages/calls/src/call.ts, related tests
Media updates are queued and resolved from matching acknowledgments. Calls expose media preferences, remote mute state, reactions, and hand-state events.
Browser media and screen sharing
packages/browser/src/calls/media.ts, packages/browser/src/calls/controller.ts, packages/browser/test/*
Browser media exchanges media-state controls and handles screen capture by replacing the outgoing video track. It restores the saved camera when sharing stops. Candidate polling avoids overlaps and backs off after a rate-limit response.
Call interfaces and localized status
packages/elements/src/calls.ts, packages/react/src/calls.tsx, packages/ui/src/locale.ts, related tests
The interfaces display remote-mute and video-delivery notices, screen-share controls, and social actions and status. The element also displays hand-raised participant labels and dedicated control-error headings.

Number selection and diagnostics

Layer / File(s) Summary
Authorized Number picker and example
packages/react/src/call-number-picker.tsx, packages/react/test/call-number-picker.test.tsx, examples/calls-example/src/*
The picker selects among supplied call controllers and disables changes during active calls. The example manages separate Number connections, selection, call state, and per-Number feedback.
Lifecycle candidate transport
packages/calls/src/client.ts, packages/browser/src/calls/client.ts, packages/browser/test/calls-candidate-integration.test.ts
Browser Calls uses lifecycle-socket candidate exchange by default. The integration test checks call scoping and HTTP candidate requests after socket disconnection.
Quality-report interval
packages/calls/src/diagnostics.ts, packages/calls/src/call.ts, packages/browser/src/calls/diagnostics.ts, related tests and documentation
Final quality reports follow the five-second interval. Tests cover delays below and at that interval.
Example guidance and status
examples/calls-example/README.md, examples/calls-example/src/main.tsx, CHANGELOG.md
The example displays call errors and failed VoIP request details. Its README documents destination restrictions and the multiple-Number flow.

Messaging and Platform contract updates

Layer / File(s) Summary
Messaging call and campaign contracts
contracts/openapi.messaging.json, packages/typescript/src/messaging/*, packages/typescript/src/webhooks/*, related tests
Messaging declarations add call-link operations and call controls. They also describe campaign rescheduling and the campaign.rescheduled webhook.
Platform rescheduling and call records
contracts/openapi.platform.json, packages/typescript/src/platform/calls.ts, packages/typescript/test/platform-calls.test.ts
Platform contracts add campaign rescheduling and call-record retrieval. The TypeScript client adds response models and validates call IDs and project scope.
Contract inventory and supporting descriptions
contracts/coverage.json, contracts/source.json, contracts/README.md, packages/typescript/src/platform/sip-trunks.ts, related tests
The contract source revision, snapshot hashes, and coverage inventory are updated. Documentation describes the refreshed operation counts and automatic SIP caller identity.

Merge Risk: 🟡 Moderate · up to dcaaa

The published OpenAPI contract for previewing a call link rejects every valid request. Spec-driven validators, mocks and generated clients will fail on that endpoint. Fix the schema in the API source and regenerate the snapshot before merging. A few smaller contract and validation concerns from earlier reviews have not been confirmed as fixed.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Add uniqueItems: true to participants.

The request description at Line 10001 requires "2 to 31 distinct recipients". The schema does not enforce that the recipients are distinct. Clients that validate against this contract accept a list such as ["+15550100","+15550100"]. Generated SDK types also accept that list, and the server then rejects it at runtime.

Document unsupported_for_connection in the new 409 responses.

The reaction and hand operations state that unsupported backends return 409 unsupported_for_connection. The ring operation states that Cloud API calls do not support it. However, each 409 response describes only state_conflict ("Call not ready"). Clients that read the response docs will not expect the other code. Change each 409 description to list both codes, as voipAddParticipant already does.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The duplicate check trims values, but the request sends the untrimmed values.

valid and the Set comparison both use value.trim(). body is still sent unchanged. A value such as " +15550100" passes validation, and the platform then receives the value with its whitespace. Reject values that contain surrounding whitespace, or send the normalized values.

Proposed fix

P1 Badge Disable the picker during pending placement

While CallsController.place() is awaiting the backend, it only sets the private #placing flag and leaves the public snapshot in ready, so this predicate remains false despite the component's promise to lock while a client places. Under ordinary request latency, the user can switch to another Number and start a second call—or the example can disconnect the first Number—before the original placement resolves, potentially leaving an unintended call active. Expose placement-in-progress in the snapshot and include it here.

P2 Badge Accept call IDs allowed by the retrieval contract

The new /platform/calls/{callId} contract in contracts/openapi.platform.json permits any 1–128 printable ASCII characters, but this validator rejects valid IDs containing characters such as . or : (and even /, which the following encodeURIComponent safely escapes). Such records therefore cannot be retrieved through the SDK even though the API accepts their identifiers; validate against the contract's printable-ASCII range rather than this narrower character set.

Move the place doc comment below placeGroup.

The new placeGroup sits between the existing place JSDoc block (Lines 249-252) and place. TypeScript attaches only the nearest JSDoc block to a declaration. As a result, place has lost its documentation, and placeGroup sits under the wrong block. Move the older comment down so that it sits directly above place.

P2 Badge Define the preview request as one closed object

The allOf makes every preview body invalid under OpenAPI 3.0 validation: the referenced VoipCreateCallLinkRequest has additionalProperties: false, so it rejects the required token, while this second closed object rejects the required session. Consequently, validators and clients generated from this contract cannot send the documented { session, token } request. Define all three properties on one closed schema, or remove the per-branch additionalProperties: false constraints.

P2 Badge Remove participants whose state is left

When the data channel sends a valid participant_state frame whose participant has state: "left", Call._remoteParticipant correctly treats it as a departure, but this parallel snapshot update checks only the frame type and therefore appends the departed participant back to current.participants. The UI then continues showing someone who left; treat a participant state of left like participant_left or derive the snapshot from the shared call roster.

P1 Badge Treat pending placement as an active call

Although CallNumberPicker now checks snapshot.placing, the fresh example-wide guard still does not. Both the disconnect button's busy state and disconnect() itself use hasActiveCall, so while the placement POST is pending and the status remains ready, the user can disconnect the Number; if the server accepted the request before the abort, the client has no returned call ID with which to end it, potentially leaving an untracked call ringing. Include snapshot.placing in this predicate as the example README promises.

P1 Badge Drain queued REST candidates after socket reconnection

When the lifecycle socket drops and reconnects before the next 5-second poll, remote ICE candidates queued during the outage are never retrieved: this condition resumes skipping every poll as soon as transport.connected becomes true, while /messaging/voip/calls/{id}/candidates is explicitly a queue that is drained only on read (contracts/openapi.messaging.json). A short socket interruption during ICE trickling can therefore leave WebRTC without required candidates and cause an otherwise recoverable call to fail; perform at least one drain after each disconnected interval before pausing polling again.

P2 Badge Ignore stale video-control failures

When the user changes video state again before the previous media-state command settles, local tracks update immediately while the commands are serialized. If the earlier command then rejects or times out, this callback invokes failedControl, disabling every local video track; the later videoEnabled: true command can subsequently succeed, but no success path re-enables the track or repairs the snapshot. A rapid mute→unmute during a transient control failure can therefore leave the camera off despite the latest state being confirmed. Gate failure cleanup by the current video-action generation or reconcile the track after each confirmed reply.
