Add Built-in Missed Calls Counter in SDK

Description:

We need a built-in mechanism to track or display the number of missed calls for users. This functionality is crucial for real-time communication apps, as it helps users stay informed about any calls they may have missed while they were offline or unavailable.

Proposed Feature:
Introduce a native missed calls counter within the SDK that:

• Automatically increments when an incoming call is not answered.

• Can be queried or displayed per user or conversation.

• Resets or adjusts once the user acknowledges or returns the call.

Benefits:

• Enhances user experience by providing better call visibility.

• Reduces the need for developers to implement custom missed call tracking logic.

• Aligns with user expectations based on common calling app behaviors.

Use Cases:

• Messaging apps with integrated calling.

• Customer support or service platforms.

• Collaboration tools where call history and engagement matter.

We believe this feature would significantly improve the usability and completeness of the calling experience within the SDK.
