Prepare the notification when the notification owns ringing.
The provider discards IncomingRingtoneOwner. Android 17 invokes this provider with IncomingRingtoneOwner.Notification after Telecom registration. This path now returns an unprepared notification because this handler no longer configures ringtone and vibration on its channel. Incoming calls that use DefaultNotificationHandler can post without ringing or vibration.

Confirmed, and the outcome is silence rather than just a missing ringtone: this provider drops the owner, getRingingCallNotification in this handler never applies configureIncomingCallAlert so there is no insistent flag, getChannelId returns the unversioned id and the channel is built without sound, and CallServiceRingingStateObserver returns early on Android 17. Nothing rings.
The class is deprecated, but it is still a public path in a shipping major.
There was a problem hiding this comment.
@aleksandar-apostolov, agreed. This is a functional regression for a supported public API path.
On Android 17, DefaultNotificationHandler can produce a silent incoming-call notification because no component configures the notification-owned ringing channel or applies FLAG_INSISTENT. The fix should preserve the IncomingRingtoneOwner in notificationProvider and prepare the notification when the owner is IncomingRingtoneOwner.Notification.

Learning: `DefaultNotificationHandler` in `stream-video-android-core/src/main/kotlin/io/getstream/video/android/core/notifications/DefaultNotificationHandler.kt` is deprecated but remains a public and supported API path in a shipping major version. For Android 17 incoming calls that use this handler, the notification provider must retain `IncomingRingtoneOwner` and prepare notifications when `IncomingRingtoneOwner.Notification` owns ringing; otherwise `CallServiceRingingStateObserver` does not provide fallback alerting and the incoming call is silent.

This class is DefaultNotificationHandler.kt, which is deprecated. So, the changes here are only required to keep the code compiling
With this PR, any notification built through DefaultNotificationHandler.kt will remain a legacy notification.
The actual changes for building ringing and non-ringing notifications are implemented in StreamDefaultNotificationHandler.kt

Honor CallServiceConfig.enableTelecom before Telecom registration.
A call type can set enableTelecom = false, but this gate does not inspect request.callServiceConfiguration. When permissions are available, the coordinator marks that call as TELECOM and registers it with Telecom anyway.
Add !request.callServiceConfiguration.enableTelecom to the fallback condition. Add a regression test for Android 17 with enableTelecom = false.

Confirmed. The Android 17 coordinator calls the single-argument canUseTelecom, and the config-aware overload is the one that consults enableTelecom — which is why the pre-17 coordinator honours it and this one does not.
Android17IncomingCallCoordinatorTest passes enableTelecom = true in every case, so nothing currently covers the disabled path.

@aleksandar-apostolov, thanks for confirming the cause and the missing test coverage.
The finding remains valid. The Android 17 fallback gate must check request.callServiceConfiguration.enableTelecom before it selects the Telecom route. Add a regression test for enableTelecom = false.

Learning: In `stream-video-android-core`, `TelecomPermissions.canUseTelecom(context)` does not inspect `CallServiceConfig.enableTelecom`. The config-aware `TelecomPermissions.canUseTelecom(callServiceConfig, context)` overload does inspect this flag. Android 17 incoming-call routing must explicitly honor `IncomingCallRequest.callServiceConfiguration.enableTelecom` when it uses the single-argument overload.

Corrected the logic, we removed the overloaded method canUseTelecom(context: Context) instead we will just use the original

Dispatch incoming-call removal by ServiceRoute.
When Telecom falls back on Android 17, the fallback coordinator sets ServiceRoute.LEGACY_CALL_SERVICE and starts CallService. Line 196 still selects Android17IncomingCallCoordinator from the OS version. Its dismissIncomingCall only cancels the notification, so the legacy remove trigger does not reach CallService. The foreground service can continue ringing.
Select the coordinator from the stored route for an existing call. Use the Android 17 coordinator only for ServiceRoute.TELECOM.

Confirmed. After a fallback the stored route is LEGACY_CALL_SERVICE and CallService is running, but getIncomingCallCoordinator still selects the Android 17 coordinator, whose dismissIncomingCall only cancels the notification — so TRIGGER_REMOVE_INCOMING_CALL never reaches the service and it keeps ringing.
call.state.serviceRoute already holds everything needed to dispatch this correctly.
