Proposed changes (including videos or screenshots)

Apps cannot see or influence media calls — the 1:1 direct audio/video calls, not video conferences. This PR adds Phase 1 ("Observe") of ADR 0003, the generic event-return protocol of ADR 0002, and the caller-facing feedback for a call an app blocks.

IMediaCallHandler

One new AppInterface with one optional method per event, shaped like IUIKitActionHandler. The interface is the subscription; each implemented method subscribes to that event.

Method When Semantics
executePreMediaCallCreated? before a call is created awaited; may pass, patch features, or prevent
executePostMediaCallStarted? media flows fire-and-forget
executePostMediaCallParticipantJoined? callee accepts fire-and-forget
executePostMediaCallEnded? call ends, any reason fire-and-forget

Decisions:

  • Contacts pass through an allow-list (type, id, username, displayName, sipExtension), so contractId — a per-session signing credential — never reaches an app.
  • The pre-create context carries origin (internal / sip-inbound / sip-outbound), derived from the two contacts, plus createdBy, parentCallId and divertedBy. Apps classify a call without reimplementing the routing rules.
  • hangupReason is a documented list plus sip-error-*, but typed open, because the stored field is free-form. helpers.ts ships isAnsweredCall / isRejectedCall / isMissedCall and isKnownMediaCallHangupReason instead of a separate missed-call event.
  • The join event needs no participant field: media calls are two-party, so the side that joins is always call.callee.

EventResult return protocol

@rocket.chat/apps-engine/definition/eventResult adds a marker-branded union: EventResult.pass() / .patch() / .prevent(). The prompt variant of ADR 0002 is specified but not shipped — no event permits it today.

Non-breaking: isEventResult() checks a reserved @kind discriminator, and consumption sites run that guard before any legacy truthiness branch.

Per-event capability is a restricted type alias, not a runtime check: MediaCallCreateEventResult = pass | patch<MediaCallCreatePatch> | prevent, where MediaCallCreatePatch = Pick<IPreMediaCallCreatedContext, 'features'>. Contacts are not patchable — they are the outcome of routing and of permission checks that already ran.

Wiring

ee/packages/media-calls must not know the Apps-Engine exists, and the pre event must be awaited. The EE package therefore declares a hook bus that the host injects into:

apps-engine definitions (IMediaCallHandler, MediaCallEvent, EventResult)
        ↓
AppListenerManager.executeMediaCallEvent      packages/apps
        ↓   pre: awaited + chained across apps; post: dispatched unawaited
appEvents.ts (toAppContact / toAppMediaCall)  apps/meteor
        ↓
MediaCallServer.setHooks({ onPreCallCreated }) ee/packages/media-calls
        ↓
CallDirector.createCall → runPreCallCreatedHook → CallRejectedError('forbidden')

First prevent wins; patches chain; workspace feature rules apply after the event, so a patch cannot bypass configuration. Post events are dispatched with void behind setImmediate, and one app that fails never blocks the others. The pre event fails closed: a throwing handler rejects the call. Only JSONRPC_METHOD_NOT_FOUND is swallowed, since every method is optional.

The caller learns why the call failed

Previously the only feedback was the call widget appearing and vanishing, which reads as a glitch.

  • CallRejectionMessage (text or i18n with a namespace) travels on the rejected-call-request signal, beside the machine-readable CallRejectedReason.
  • ClientMediaCall emits rejected only on the session that requested the call — the same signal reaches every session of the user, and the rest are hidden.
  • useCallRejectionToast shows it. An app's i18n key resolves under app-<appId>; an unresolvable key falls back to a generic message rather than rendering the key. A text message is truncated to 200 characters.
  • Reasons the server was already sending (busy, unavailable, forbidden, unsupported, invalid-call-params) now get their own strings. The four that mean "a client sent a request it should not have" stay silent.

An inbound SIP call that an app blocks is answered with 403 Forbidden instead of surfacing the error.

Drive-by fix

A call's createdBy was stored with an id and nothing else on every call that was not a transfer. It now carries the same contact information as caller and callee, which also fixes the transferredBy sent to clients.

Tests

  • AppListenerManager.mediaCalls.test.ts (node:test) — 14 tests: pass/patch/prevent, patch chaining, unsupported patch keys, non-EventResult values, fail-closed, post-event routing.
  • appEvents.spec.ts (mocha) — 37 tests: no contractId on any event, origin derivation, omitted vs undefined optional fields, durationMs, rejection-message mapping, and a check that mediaCallHangupReasonList still covers the server's reasons.
  • Call.spec.ts and useCallRejectionToast.spec.tsx (jest) — 11 tests over the path from the signal to the toast.
  • media-call-events.spec.ts (Playwright, needs a running EE workspace) — 7 tests driving a committed fixture app through real calls.

The e2e app-log helpers moved to tests/e2e/utils/apps.ts; uikit-interactions.spec.ts now uses them.

Issue(s)

Implements Phase 1 of ADR 0003 (added here, together with ADR 0002; both supersede the proposals they replace).

VVCLA-1

Steps to test or reproduce

You need an EE workspace with media calls enabled (enterprise + teams-voip) and two users with extensions.

  1. yarn workspace @rocket.chat/apps-engine build && yarn workspace @rocket.chat/apps test:node
  2. cd apps/meteor && yarn .testunit:server --grep "media call app events"
  3. yarn workspace @rocket.chat/media-signaling test && yarn workspace @rocket.chat/ui-voip testunit
  4. Install apps/meteor/tests/data/apps/app-packages/media-call-events-test_0.0.1.zip as a private app. It logs what each event handed it. Switch its pre-event answer with POST /api/apps/public/<appId>/mode, body { "mode": "pass" | "prevent" | "drop-screen-share" }.
  5. pass: place a call, answer, let media flow, hang up. Expect post_joined_*, post_started_* and post_ended_* entries, a matching post_ended_duration_ms, and post_ended_outcome: answered. pre_created_caller_keys must not include contractId.
  6. prevent: the caller gets a rejected call and a toast with the app's reason.
  7. drop-screen-share: request a call with screen-share; the created call comes back without it, other features intact.
  8. Decline a call, then let one ring out: post_ended_outcome reads rejected and then missed.
  9. The same paths are automated in test.describe('Apps > Media call events').

Further comments

Why the EE hook bus. ee/packages/media-calls has no Apps-Engine dependency and the pre event must be awaited, so an emitter event would not do. MediaCallHooks keeps the dependency pointing the right way: the EE package declares the hook it awaits, the host decides what sits behind it. Phase 2/3 hooks join that type.

Deliberate gaps, recorded in ADR 0003:

  • No IMediaCallRead accessor — an app sees only the calls events hand it.
  • No MEDIA_CALL association — events go to every app implementing IMediaCallHandler.
  • An internal call routed over SIP fires two unlinked events, one per leg. ADR 0003 rejects correlating them; the outbound leg cannot know the PBX will route it back.
  • Phase 2IMediaCallModify (hangup/transfer/sendDTMF) and the remaining post events.
  • ee/packages/media-calls has no test harness — no test script, no specs. CallDirector's hook branch and the IncomingSipCall rejection mapping are covered by Playwright only. Standing up a runner there is a prerequisite for unit-testing Phase 2/3.

Build coupling for reviewers: the host imports from @rocket.chat/apps/dist, so packages/apps needs a rebuild after packages/apps-engine edits, and packages/apps-engine's definition/ output is what the Meteor-side tests resolve.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🔵 Low · up to d0650

The PR adds media-call app hooks and caller rejection feedback. It is mergeable with explicit owner follow-up for two bounded risks: E2E VoIP settings may contaminate neighboring tests, and a stalled app handler may prevent later apps from receiving the same lifecycle event.

`createdBy` is derived from the user who requested the call, which reaches
the server carrying nothing but an id and a contract. Only the caller and
callee were resolved into full contacts, so every call that was not created
by a transfer - transfers inherit theirs from the call being transferred -
was stored with a `createdBy` that had no username or display name on it,
and clients were told the same on `transferredBy`.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The two most behaviour-dense files of the media call app events had no unit
coverage: the mapping layer in `appEvents.ts` was only reached through the
Playwright suite, and the dispatch layer was pinned for one post method out of
three.

`appEvents.spec.ts` covers the mapping layer, including the security-relevant
part: no contact's `contractId` reaches an app on any event. Also the
`durationMs` arithmetic with its clamp and `Date.now()` fallback, the
`Apps.self`-absent and call-not-found guards, and each event envelope.

`AppListenerManager.mediaCalls.test.ts` gains the started and participant-joined
routing, the two warn branches (unsupported patch key, unsupported `EventResult`
variant), return values that are not `EventResult`s, the `check` opt-in, and the
fail-closed behaviour of both pre methods — which nothing pinned, despite being
the reason a throwing app refuses a call rather than letting it through.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The only changeset on the branch covered the `createdBy` bugfix, so the feature
itself would have shipped without a release note.

Also records in the proposal what Phase 1 deliberately leaves open, so those gaps
are not mistaken for oversights: the prevention reason never reaching the caller
(and `i18n.args` being dropped on the way), the missing `IMediaCallRead` accessor
and `MEDIA_CALL` association, and the fact that `ee/packages/media-calls` has no
test harness at all — which is why `CallDirector`'s pre-hook branch and the
`IncomingSipCall` rejection mapping are covered by Playwright alone.

Three levels, since no single one of them sees the whole thing:

- media-signaling, on which sessions hear about a rejection and which stay
  quiet. These are the package's first specs, so it also gains the jest
  config it was missing.
- ui-voip, on what the caller ends up reading - and, in particular, that an
  app naming a translation it never shipped falls back instead of putting a
  raw key on screen.
- e2e, on the whole chain: the fixture app blocks a call and its own words
  come back in a toast.

The i18n branch stops at the unit tests. Exercising it end to end means
teaching the fixture app a new mode, and repackaging its zip needs the apps
CLI, which isn't installed here.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The analysis doc listed "the prevention reason never reaches the caller" as
a Phase 1 follow-up; record how it was resolved and where each hop of the
path now lives, so the next reader doesn't go looking for a gap that is no
longer there.

Add a test for a pre-create handler that throws.

Fail-closed behavior for errors in pre-create handlers is one of the stated goals of this change. runPreMediaCallCreatedAppHook does not catch, so a rejected triggerEvent propagates and createCall rejects the call. No test in this describe block pins that behavior, so a future try/catch added anywhere in the path would silently turn the hook fail-open.

💚 Suggested test
it('does not let the call through when an app handler fails', async () => {
	triggerEvent.rejects(new Error('app exploded'));

	await expect(runPreMediaCallCreatedAppHook(hookParams())).to.be.rejectedWith('app exploded');
});

chai-as-promised is required for rejectedWith. If it is not registered in this suite, assert with a try/catch instead.

Inline comments:
In `@apps/meteor/tests/e2e/apps/media-call-events.spec.ts`:
- Line 145: Replace the CSS-based locator in the media call event test’s
error-toast assertion with a semantic role-based toast locator or the existing
toast page object assertion, while preserving the expectation that the error
toast is not visible.
- Around line 67-69: Capture the existing VoIP_TeamCollab_Screen_Sharing_Enabled
value before setSettingValueById changes it, then restore that value in the
suite’s afterAll teardown. Ensure restoration runs even if page cleanup fails by
placing it in a finally path, while preserving the existing cleanup behavior.

In `@ee/packages/media-calls/src/server/CallDirector.ts`:
- Around line 215-230: Update the pre-call hook flow around
runPreCallCreatedHook and executePreMediaCallCreated so a timed-out
ProxiedApp.call is propagated as a rejection instead of becoming undefined or an
allowed result. Preserve fail-closed behavior by preventing call creation when
the policy handler exceeds its timeout, while retaining normal prevented and
successful hook handling.

In `@packages/apps/src/server/managers/AppListenerManager.ts`:
- Around line 1371-1385: Update executePostMediaCallEvent to initiate all
app.call invocations before awaiting completion, rather than awaiting inside the
listener loop. Preserve the existing JSONRPC_METHOD_NOT_FOUND suppression and
error logging for each handler, and await the collection of started calls after
the loop so one stalled app does not block notifying others.

Nitpick comments:
In `@apps/meteor/tests/e2e/apps/media-call-events.spec.ts`:
- Around line 21-44: Remove the newly added implementation comments while
preserving the associated code: in
apps/meteor/tests/e2e/apps/media-call-events.spec.ts lines 21-44, remove
comments describing Mode, entryValue, and suite behavior; in
apps/meteor/tests/e2e/page-objects/fragments/voice-calls.ts line 137, remove the
btnClose comment; and in apps/meteor/tests/e2e/utils/apps.ts lines 61-67, remove
the shared-helper implementation comments. Use existing test names, step labels,
and symbol names as documentation instead.

In `@apps/meteor/tests/unit/server/services/media-call/appEvents.spec.ts`:
- Around line 381-387: Add a test in the runPreMediaCallCreatedAppHook describe
block that makes triggerEvent reject and asserts the rejection propagates with
the original error, preserving fail-closed behavior; use the suite’s supported
async rejection assertion or a try/catch if chai-as-promised is unavailable.

In `@packages/apps-engine/src/definition/mediaCalls/helpers.ts`:
- Around line 41-57: Remove the embedded application-handler code example from
the JSDoc in isMissedCall, leaving only the implementation-relevant description;
do not add replacement comments or refactor surrounding logic.

In `@packages/apps-engine/src/definition/mediaCalls/IMediaCall.ts`:
- Around line 101-107: Update the IActiveMediaCall, IAcceptedMediaCall, and
IEndedMediaCall aliases to override lifecycle state fields with the exact state
and ended values produced by each transition, while preserving their existing
required timestamp fields. Ensure IEndedMediaCall also enforces ended: true so
impossible combinations such as an ended ringing call are rejected.

In `@packages/media-signaling/src/definition/call/common.ts`:
- Around line 15-25: Remove the implementation-only explanatory comments without
changing behavior: packages/media-signaling/src/definition/call/common.ts lines
15-25, packages/media-signaling/src/definition/call/CallEvents.ts lines 33-35,

apps/meteor/tests/e2e/**/*.spec.ts: All test files must be created in apps/meteor/tests/e2e/ directory
Avoid using page.locator() in Playwright tests - always prefer semantic locators such as page.getByRole(), page.getByLabel(), page.getByText(), or page.getByTitle()
Use test.beforeAll() and test.afterAll() for setup/teardown in Playwright tests
Use test.step() for complex test scenarios to improve organization in Playwright tests
Group related tests in the same file
Utilize Playwright fixtures (test, page, expect) for consistency in test files
Prefer web-first assertions (toBeVisible, toHaveText, etc.) in Playwright tests
Use expect matchers for assertions (toEqual, toContain, toBeTruthy, toHaveLength, etc.) instead of assert statements in Playwright tests
Use page.waitFor() with specific conditions instead of hardcoded timeouts in Playwright tests
Implement proper wait strategies for dynamic content in Playwright tests
Maintain test isolation between test cases in Playwright tests
Ensure clean state for each test execution in Playwright tests
Ensure tests run reliably in parallel without shared state conflicts

Learning: In the Rocket.Chat repository, do not reference Biome lint rules in code review feedback. Biome is not used even if biome.json exists; only reference Biome rules if there is explicit, project-wide usage documented. For TypeScript files, review lint implications without Biome guidance unless the project enables Biome rules.

Learning: In this repository (RocketChat/Rocket.Chat), Biome lint rules are not used even if a biome.json exists. When reviewing TypeScript files (e.g., packages/ui-voip/src/providers/useMediaSession.ts), ensure lint suggestions do not reference Biome-specific rules. Rely on general ESLint/TypeScript lint rules and project conventions instead.

Learning: Field wrappers in rocket.chat/fuselage-forms (Field, FieldLabel, FieldRow, FieldError, FieldHint) auto-create htmlFor/id associations, aria-describedby, and role="alert" for errors. Do not manually set htmlFor, id, aria-describedby, or role attributes when using these wrappers. This automatic wiring does not apply to plain rocket.chat/fuselage components, which require explicit ID wiring per the accessibility docs. In code reviews, prefer using fuselage-forms wrappers for form fields and verify there is no unnecessary manual ID/aria wiring in files that use these wrappers. If a component uses plain fuselage components, ensure proper id wiring as per docs.

Learning: For TSX files in the UI VOIP package, ensure that when a media session state is 'unavailable', the voiceCall action is excluded from the actions object passed to CallHistoryActions so it does not render in the menu. This filtering should occur upstream (before getItems is called) to avoid tooltips or UI hints for unavailable actions. If there are multiple actions with availability states, implement a centralized helper to filter actions based on session state.

Learning: In Rocket.Chat’s `packages/ui-voip` UI (e.g., media/call widgets), voice/media calls are only supported in Direct Message (DM) rooms. Rocket.Chat models a DM as a “room” with exactly two participants, so handlers like `onClickDirectMessage` are the correct destination—even when the UI text/element says “Open in room” (e.g., on the shared screen card/`StreamCard`). During review, don’t flag a “DM vs room” mismatch for these cases; they intentionally map to the same destination.

Learning: In tests (especially those using testing-library/dom/jsdom) for Rocket.Chat components, the HTML <code> element has an implicit ARIA role of 'code'. Therefore, screen.getByRole('code') or screen.findByRole('code') will locate <code> elements even without a role attribute. Do not flag findByRole('code') as invalid in reviews; prefer using the implicit role instead of adding role="code" unless necessary for accessibility.

Learning: In Rocket.Chat, there are two different `ModalBackdrop` components with different prop APIs. During review, confirm the import source: (1) `rocket.chat/fuselage` `ModalBackdrop` uses `ModalBackdropProps` based on `BoxProps` (so it supports `onClick` and other Box/DOM props) and does not have an `onDismiss` prop; (2) `rocket.chat/ui-client` `ModalBackdrop` uses a narrower props interface like `{ children?: ReactNode; onDismiss?: () => void }` and handles Escape keypress and outside mouse-up, and it does not forward arbitrary DOM props such as `onClick`. Flag mismatched props (e.g., `onDismiss` passed to the fuselage component or `onClick` passed to the ui-client component) and ensure the usage matches the correct component being imported.

Learning: In Playwright end-to-end tests (e.g., under apps/meteor/tests/e2e/...), prefer locating elements by translated text (getByText) and ARIA roles (getByRole) over data-qa attributes. If translation values change, update the corresponding test locators accordingly. Never use data-qa locators. This guideline applies to all Playwright e2e test specs in the repository and helps keep tests robust to UI text changes and accessible semantics.

The media-call events spec called `Widget.endCall()`, which the page object
does not define.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
executePostMediaCallEvent awaited each handler in turn, so an app that stalls
until its runtime request times out delayed every app behind it. The events are
fire-and-forget, so start them all and await the set.

Also route the e2e toast assertion through the page object, and cover that a
failed pre-create event fails the call instead of passing it.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The listener loop rethrows the errors it sees, so a throwing app blocks the
call. A timed-out request never reaches that branch: ProxiedApp.call swallows
it and returns undefined, which the loop reads as "no result". Every pre-event
in the engine behaves this way, so record the gap rather than close it here.

Also document the throw contract for app authors and why the post events are
the one executor that dispatches concurrently.

Learning: In this repository (RocketChat/Rocket.Chat), Biome lint rules are not used even if a biome.json exists. When reviewing TypeScript files (e.g., packages/ui-voip/src/providers/useMediaSession.ts), ensure lint suggestions do not reference Biome-specific rules. Rely on general ESLint/TypeScript lint rules and project conventions instead.

Learning: Field wrappers in rocket.chat/fuselage-forms (Field, FieldLabel, FieldRow, FieldError, FieldHint) auto-create htmlFor/id associations, aria-describedby, and role="alert" for errors. Do not manually set htmlFor, id, aria-describedby, or role attributes when using these wrappers. This automatic wiring does not apply to plain rocket.chat/fuselage components, which require explicit ID wiring per the accessibility docs. In code reviews, prefer using fuselage-forms wrappers for form fields and verify there is no unnecessary manual ID/aria wiring in files that use these wrappers. If a component uses plain fuselage components, ensure proper id wiring as per docs.

Learning: In Playwright end-to-end tests (e.g., under apps/meteor/tests/e2e/...), prefer locating elements by translated text (getByText) and ARIA roles (getByRole) over data-qa attributes. If translation values change, update the corresponding test locators accordingly. Never use data-qa locators. This guideline applies to all Playwright e2e test specs in the repository and helps keep tests robust to UI text changes and accessible semantics.

Learning: In tests (especially those using testing-library/dom/jsdom) for Rocket.Chat components, the HTML <code> element has an implicit ARIA role of 'code'. Therefore, screen.getByRole('code') or screen.findByRole('code') will locate <code> elements even without a role attribute. Do not flag findByRole('code') as invalid in reviews; prefer using the implicit role instead of adding role="code" unless necessary for accessibility.

Learning: In Rocket.Chat UI Kit e2e tests, when testing `executeBlockActionHandler` flows that originate from a **modal** surface, do not treat a missing `block_action_room` / room property in the interaction payload as a test-coverage failure. Modals are not room-scoped, so the room id should be unavailable in this context. Document this explicitly in the test by using `test.step` (or equivalent) to assert the room entry is `undefined`.

Learning: In `packages/apps/src/server/managers/AppListenerManager.ts`, `executePostMediaCallEvent` must start all `IMediaCallHandler` post-event calls before awaiting them because post events have no result dependency and sequential calls can accumulate per-app runtime timeouts. `executePreMediaCallCreated` must remain serial because `prevent` short-circuits and `patch` results must chain.

Learning: In Rocket.Chat’s `packages/apps/tsconfig.json`, TypeScript `"strict"` is set to `false`, which disables strict type-checking (including `noImplicitAny`) for `packages/apps`. When reviewing, do not flag TS7053 (and similar strict-mode indexing/type errors) in files under `packages/apps/src/` that are a consequence of this relaxed strictness—e.g., patterns like indexing an `unknown`/`object` via optional chaining such as `object?.[kSecureFields]`.

Timestamp: 2026-08-19T14:02:22.275Z
Learning: In Rocket.Chat Apps-Engine, `packages/apps/src/server/ProxiedApp.ts` currently swallows plain runtime errors, including request timeouts, by returning `undefined`. Existing pre-events therefore fail open on a timeout. `executePreMediaCallCreated` rethrows errors that reach it except `JSONRPC_METHOD_NOT_FOUND`, so thrown media-call pre-create handler failures fail closed. Changing timeout behavior requires a shared Apps-Engine policy and mechanism, not a media-call-specific change.

P2: When an app patches a SIP call, this line can reintroduce features that the SIP provider deliberately removed, such as screen-share. Re-apply SIP_CALL_FEATURES for either SIP direction after the hook and before storing the call features.

P2: When a call progresses quickly, independent deferred reads can deliver lifecycle events out of order to apps. Serialize post notifications per call, or pass event-time snapshots through the emitter, so an app cannot observe ended before participantJoined or started.

P3: This spec flips the global VoIP_TeamCollab_Screen_Sharing_Enabled setting to true in beforeAll but never restores it in afterAll, while another spec (voice-calls-ee.spec.ts) toggles the same setting. The repo's e2e cleanup guidance says to reset settings to defaults, and leaving a shared server setting mutated makes test order/previous-value matter. Capture the prior value (or restore the default) in beforeAll/afterAll so the run does not change this setting permanently.
