+## Start time
 
 The ability to use **call start time events** allows developers to capture and utilize the exact time a call is initiated. By subscribing to these events, developers gain valuable insights that can be applied in various use cases, such as performance tracking and user experience enhancements, among other uses.

-#### Enhanced User Experience
+#### Enhanced user experience
 Developers can use the call start time to display call duration to users in real time, improving the user experience by providing transparency on how long the user has been in the call.
 
 **Example:** In a video conferencing app, the UI can display an active call timer showing how long the participants have been in the meeting, increasing user engagement.
 
 By utilizing the call start time API events, developers can build more robust, feature-rich applications that improve the user experience, ensure compliance, and support detailed performance monitoring.
 
-#### Performance and Monitoring Analytics
+#### Performance and monitoring analytics
 By retrieving the call start time, developers can measure call duration and integrate with monitoring systems to analyze the performance of calls. This information is crucial for identifying call quality issues, optimizing network performance, and understanding user behavior.
 
 **Example:** A customer support center can track how long agents stay on calls and identify trends related to call durations, improving resource management.
