How stop the call when caller ends call?

[ScottLee97]

A user calls someone and the backend would send out an FCM data-only message to the receiver which triggers the call. But what if the caller ends the call before the receiver picks up the call? Is there a way to end the call on the receiver's side when the caller ends call?

No, you must control it by yourself.

I start calls with FCM data push messages (the app can be closed) and end them with Firestore Database (app is open and listening call-room changes).

Is it possible to start and end the call when the app is in the background? In other words, can the listening of call-room changes be done even when the app is in the background??

No, when the app is terminated or backgrounded (even iOS) your listeners will stop receiving changes. Use push data messages to do that.
