During a call, a user may join and leave a RTC channel for multiple times, and the user's call duration is the actual time when the user is in the channel. You can use the the Agora RTC SDK or Agora Analytics to get a user's call duration.
By design, the SDK triggers the
onRtcStats callback after a user successfully joins a RTC channel. To get the duration between each channel-join and channel-leave, use the
totalDuration parameter of the last
onRtcStats callback triggered before the user leaves the channel. If a user joins and leaves a RTC channel for multiple times, you can calculate the user's call duration by adding up the values of
If the connection is lost under poor network conditions, the calculated duration maybe inaccurate. Use Agora RTM SDK 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 RTC SDK.
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.
