If a user joins and leaves a Video SDK channel for multiple times, you can calculate the user's call duration by adding up the values of `totalDuration`.
 
 The above callback is in Java. For other programming languages, use the following parameters to get the user's call duration:
 - C++: The `duration` parameter of the `onRtcStats` callback.
-- Objective-C: The `duration` parameter of the [reportRtcStats](https://api-ref.agora.io/en/video-sdk/ios/3.x/Protocols/AgoraRtcEngineDelegate.html#//api/name/rtcEngine:reportRtcStats:) callback.

 - Javascript: The `Duration` parameter of the `Client.getSessionStats` method.
 
 If the connection is lost under poor network conditions, the calculated duration maybe inaccurate. Use [Agora Signaling SDK](/signaling/develop/manage-connection-states) or a different signaling system to implement a heartbeat mechanism, and get the disconnected time of the client. You can calculate the user's call duration by subtracting the disconnected time of the client from the call duration obtained from the Agora Video SDK.
 
 ### Use Agora Analytics
 
-On the **Call Search** page of **Agora Analytics**, you can find a user's call duration in the **In-call Periods** column. See [Call Search](/agora-analytics/analyze/video-voice-sdk/call-search#search).
