The app I'm making uses the CallDirectory extension to identify callers. Where is the contact data added by "func addIdentificationEntry" in "CallDirectory Extension" stored? The app calls "CXCallDirectoryManager.sharedInstance.reloadExtension" and adds contact data by processing "CXCallDirectoryExtensionContext.addIdentificationEntry" written in "func beginRequest" of "CallDirectory Extension". I thought that if I uninstalled the app, I would lose the contact data that added by App. However, when I uninstalled the app and reinstalled it, it seemed to retain contact data that added by App before I uninstalled the app, even though the app hasn't added any contact data yet. Will the contact data added to the "CallDirectory Extension" be retained on iPhone even after uninstalling the app? ---Note--- I found a similar post on the forum about contact data added by addIdentificationEntry. ・CallKit - addIdentificationEntry is it secure? [https://developer.apple.com/forums/thread/662182] Answer of this post that "the added data is cached in a SQLite database", but I couldn't find any official Apple documentation on this, so I'm not sure if this is correct. If contact data is cached in SQLite, will that data remain on the iPhone when uninstalled and not deleted? ●Development environment Mac OS Sonoma 14.7.1 Xcode 16.0 Swift ●Test Device iPhoneSE3 iOS:17.6.1

Hello, I am currently developing a call service using CallKit and VoIP push. Recently, I have encountered a very challenging issue. During testing, when a VoIP push is received, the incomingCall gets triggered continuously, but then it automatically terminates after about 1-2 seconds. I am checking this issue under the debug scheme, and even when switching to different commits, the same problem persists. I suspect it might be an issue with the device, but I would like to confirm the cause and find a solution. Below are some characteristics I have noticed: On this device, when a VoIP push is received, CallKit automatically terminates, but this does not occur when debugging. The issue always occurs when not debugging. Looking at the device console logs related to callservicesd, there are many logs with 'invalidate' appended. For example: Invalidating process assertion for bundle ID from timeout All calls ended. Clearing system uplink muted cache Invalidate callDurationUpdateTimer InCallService has changed process state to 2 InCallService has been suspended; invalidating its XPC client connections. [0x565544180] invalidated because the current process cancelled the connection by calling xpc_connection_cancel() XPC connection invalidated from client These logs appear although our server did not receive any incoming call request, so we did not terminate it on our end. I also checked if there was a crash, but there were no reports left on the device. Could you please share any insights into the cause or solutions for this situation? Thank you.

I am trying to add voip call functionality to my app. It works as expected while the app is in the foreground. But in the background it does not. I have registered the app as requiring background voip permissions. My implementation doesn't fit into one of these posts, so here is a gist: https://gist.github.com/BrentMifsud/4be43c022c1279f04ecb56250a86b3f1

We have just been granted access to the com.apple.developer.usernotifications.filtering entitlement, and are following the documented steps for handled E2EE VOIP notifications listed here: https://developer.apple.com/documentation/callkit/sending-end-to-end-encrypted-voip-calls 1 - A user initiates a VoIP call on their app. Their app then sends an encrypted VoIP call request to your server. We do exactly this, Alice calls Bob from her app, sending a notification to our servers. 2 - Your server sends the encrypted data to the receiver’s device using a regular remote notification. Be sure to set the apns-push-type header field to alert. We do exactly this, our server send on a notification to APNS with the apns-push-type header set to alert, destined for Bob. 3 - On the receiver’s device, the notification service extension processes the incoming notification and decrypts it. If it’s an incoming VoIP call, the extension calls reportNewIncomingVoIPPushPayload(_:completion:) to initiate the call. It then silences the push notification (see com.apple.developer.usernotifications.filtering). I try to do exactly this. The notification is received by the NSE on Bob's device, which decrypts it and then notices it is a VOIP call from Alice. It prepares a dictionaryPayload with the decrypted data and then calls reportNewIncomingVoIPPushPayload(_:) async throws. This throws an NSXPCConnectionInterrupted error, which when logged shows as below: Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.callkit.notificationserviceextension.voip" UserInfo={NSDebugDescription=connection to service named com.apple.callkit.notificationserviceextension.voip} The only difference I can see to the documentation is that I am working in an asynchronous context so am using the asynchronous version of the method, but I don't imagine this should cause an issue? I then supress the notification as documented and this works correctly. Does anyone have any ideas why I am getting this error when calling reportNewIncomingVoIPPushPayload(_:) async throws?

Hello, I’m working on a caller ID app and with the release of iOS 18.2, Apple has introduced the ability to set a third-party app as the default calling app. I have followed the official documentation for this feature and successfully set my app as the default phone app for making and receiving calls. Documentation Reference: https://developer.apple.com/documentation/callkit/preparing-your-app-to-be-the-default-calling-app Now, I’m facing some challenges and need some guidance: Custom UI for Incoming Cellular Calls: Is it possible to show a custom UI when receiving SIM-based cellular calls (not VoIP)? I want to replace the default iOS call screen with my own design when a cellular call is received. Can CallKit allow me to manage and display this custom UI for real cellular calls? Detecting Incoming Cellular Calls: Can I detect incoming SIM-based cellular calls when my app is set as the default calling app? I would like to track and show details of incoming calls (e.g., caller information, call duration) using a custom interface. Displaying Call Data (Call Duration, Recent Calls): Can I show call data (e.g., call duration, recent call history, etc.) for SIM-based cellular calls within my app when it is the default calling app? I need to know if it’s possible to retrieve and display this data in a custom format. Managing Outgoing Cellular Calls: For SIM-based outgoing calls, can I handle the process of initiating the call and then show a custom UI for the call in progress (similar to how VoIP apps manage outgoing calls)? I understand that CallKit can be used to manage the UI for calls, but I’m unsure about the limitations when it comes to real SIM-based cellular calls. Is it possible to implement these features with the current API capabilities, or are there any restrictions I should be aware of when managing cellular network calls? Thanks in advance for your help!

iOS 18 (22A3354) will not offer a option in settings (> Apps > Phone) after calling openSettings to enable live caller id lookup extension. iPhone and MacBook are in the same network. The PIRService runs on MacBook and is reachable via iPhone Safari (via http://MacBookPro:8080/). Hummingbird print log: hb_method=GET hb_uri=/ [Hummingbird] Request. After deploying the application via Xcode to the iPhone no requests are printed in the terminal. The extension was added like documented and bundle id is also checked multiple times. issuerRequestUri in service-config.json is http://MacBookPro:8080/issue. As far as I can tell, everything has been set up in accordance with the Testing Live Caller ID instructions. Is there something missing?

Hello Apple Developer Community, I'm developing a call-blocking app for iOS and have encountered an issue with iOS 18. Despite calls being successfully blocked by our app's Call Directory extension, they are still appearing as unanswered calls in the native Phone app. Details: iOS version: 18 App uses CallKit and Call Directory extension Calls are blocked successfully (not ringing on device) Blocked calls show up as "Unanswered" in Phone app's recent calls list Expected behavior: Blocked calls should not appear in the Phone app's recent calls list. Actual behavior: Blocked calls appear as "Unanswered" in the recent calls list.

I have been playing around with getting the Live Caller ID example project setup yet I cannot get passed the initial configuration. I have the app extension running on my device and the server running on the correct host and port so things are working in that sense, yet when I go to the Call Blocking & Identification Services to toggle on my extension I see that the /config endpoint is failing with the following error: Invalid existingConfigIds count 1. Expected 0 or 0. The existingConfigIds has one entry with a Data object of zero bytes. I’m not sure where/why this is getting added upon initialization. Has anyone seen this occur? I followed the testing instructions as far as I can tell and haven’t seen this issue discussed elsewhere.

I am working on Agora Voice Call and using CallKit to manage incoming and outgoing calls. Issue: When I accept a call, CallKit goes behind my app. I want CallKit to remain in front of my app. Please guide me.

I've been testing the Live CallerID feature using the Apple-provided local server example - live-caller-id-lookup-example. I've been running a local server with tunneling using ngrok for the initial setup. Everything was working perfectly with the following setup: @main final class CallerID: LiveCallerIDLookupProtocol { var context: LiveCallerIDLookupExtensionContext { LiveCallerIDLookupExtensionContext( serviceURL: URL(string: "https://example-tunnel.ngrok.io")!, tokenIssuerURL: URL(string: "https://example-tunnel.ngrok.io")!, userTierToken: Data(base64Encoded: "BBBB")! ) } } However, after I updated the URLs to the production ones, I encountered an issue: @main struct CallerID: LiveCallerIDLookupProtocol { var context: LiveCallerIDLookupExtensionContext { LiveCallerIDLookupExtensionContext( serviceURL: URL(string: "https://example.net/")!, tokenIssuerURL: URL(string: "https://example/issue")!, userTierToken: Data(base64Encoded: "BBBB")! ) } } The problem is that during calls or when updating PIR parameters, the application still attempts to connect to the initial ngrok tunnel URLs instead of using the new production URLs. I can confirm this because the logs on my local server show incoming requests, indicating that the application is still referencing the old ngrok tunnel URLs. Steps I’ve taken to resolve the issue include: Deleting and reinstalling the application. Using reset(forExtensionWithIdentifier:) Unfortunately, these attempts have not been successful. I even extracted the binary of the app and extension to inspect the strings, confirming that the correct production URLs are present. The server was started with the following command: PIRService --hostname 127.0.0.1 service-config.json Could this be some sort of caching bug on the iOS side, or am I missing something?

Following up on a previous thread that was marked as resolved, we're observing that the behavior of blocked calls in iOS 18.2 hasn't changed as indicated. Current behavior in iOS 18.2: Calls blocked by Call Directory extensions still appear as "unanswered" in the Phone app's call history The calls are successfully blocked (don't ring) though There's no indication in the call history that these calls were blocked Expected behavior (as previously indicated would be fixed in iOS 18.2 beta 3): Blocked calls should be labeled as "Blocked" Should show which app blocked them This continues to cause confusion among users who expect blocked calls to either be clearly labeled or not appear in their history at all. We're still receiving regular user complaints about this behavior. Has there been any change in the timeline for addressing this? Any information would be helpful for both developers and users. Thank you in advance.

What determines whether the live caller ID call extension sends a /queries request with an EvaluationKey instead of an EvaluationKeyMetadata.Identifier? Is this behavior configurable through our app? In the live-callerid-lookup-example, the code checks if the PirRequest contains an EvaluationKey and uses it for evaluation if present; otherwise, it defaults to the uploaded key. However, during testing with the live caller ID extension, we observed that the client system (iPhone) consistently sends /queries requests using only EvaluationKeyMetadata.Identifier. Is it possible for the client to send queries with an EvaluationKey to reduce storage requirements? In the "Refresh the Data" section, it is mentioned that "The system periodically refreshes these parameters automatically." Could you provide more details on the specific timing or frequency of these automatic refreshes? For example, do factors such as Low Power Mode, power-saving mode, or a screen-locked state affect the frequency or occurrence of these updates?

When Call Blocking and Identification is enabled, information such as Caller Name, number and Call Identification Label is displayed correctly in the incoming call screen. But in Recents screen the call record is not displaying any name or number but instead displays only the Call Identification label that was passed in CXCallDirectoryProvider is displayed. Note: This issue is not observed when the call blocking and identification permission is not granted and the same code is working fine in iOS 17.x

I am developing a VOIP app which should also work in China region. I want to detect whether there are any other calls active or ended. This functionality is can be achieved using Callkit CXCallObserver. But CallKit cannot be used in China. So is there any other alternative way to achieve what CXCallObserver offers?

Our company application uses callkit for livestream but is not available in china which make Apple not to approve the app. can any one help with what i can do. The live stream is one of the key feature of the app. Or is it possible to restrict download from china

How can I show my VoIP calling app in the same list as Facetime and Whatsapp as shown in the image? My app implements VoIP calls and is integrated with CallKit. Any tip would be appreciated!

I noticed the following behavior with CallKit when receiving a VolP push notification: When the app is in the foreground and a CallKit incoming call banner appears, pressing the answer button directly causes the speaker indicator in the CallKit interface to turn on. However, the audio is not actually activated (the iPhone's orange microphone indicator does not light up). In the same foreground scenario, if I expand the CallKit banner before answering the call, the speaker indicator does not turn on, but the orange microphone indicator does light up, and audio works as expected. When the app is in the background or not running, the incoming call banner works as expected: I can answer the call directly without expanding the banner, and the speaker does not turn on automatically. The orange microphone indicator lights up as it should. Why is there a difference in behavior between answering directly from the banner versus expanding it first when the app is in the foreground? Is there a way to ensure consistent audio activation behavior across these scenarios? I tried reconfiguring the audio when answering a call, but an error occurred during setActive, preventing the configuration from succeeding. let audioSession = AVAudioSession.sharedInstance() do { try audioSession.setActive(false) try audioSession.setCategory(.playAndRecord, mode: .voiceChat, options: [.defaultToSpeaker]) try audioSession.setActive(true, options: []) } catch { print("Failed to activate audio session: \(error)") } action.fulfill() } Error Domain=NSOSStatusErrorDomain Code=561017449 "Session activation failed" UserInfo={NSLocalizedDescription=Session activation failed}

I am currently working on implementing the Live Caller ID Extension for my iOS app, and I understand that a backend server is required for this functionality. While I’ve gone through Apple’s documentation, the details on the backend setup are limited and not very clear for my backend team to implement it effectively. Could someone provide a more detailed explanation or sample implementation of the backend server required for this extension? Specifically, we are looking for: A clear understanding of the APIs and endpoints the backend needs to expose. Any authentication mechanisms required for communication with the extension. Data format (e.g., JSON structure) for requests and responses. Example code or additional resources, if available. Any help or guidance in understanding the exact backend requirements would be greatly appreciated.

I've found an app that has a call blocking feature an is able to add more than 10_000_000 entries. As I understand it doesn't use more than one extension for it because I see only one in the Call Blocking & Identifying settings menu. How to implement that? My limit now is around 1_800_000 entries.
