@AE-IT and
@cobaltit "EXIT - Ignore PUSH" will not come back... Reason is stated here:
https://www.3cx.com/docs/android-app-faq/#h.lcteeu5yq5kd
Quoting;
"Exit without push has been removed because Firebase servers do not like receiving high priority message requests.
When the user sets
“Exit without push”, the app/device informs the Firebase server to unsubscribe. The 3CX PBX however, still assumes that it has to send requests on calls, so it sends an unwanted High priority message to Firebase global servers. In return, the server receives something to process even though the user has already requested not to be notified.
If this happens too often, Firebase has the right to block PUSH requests. This is the reason PUSH might not work, and why
“Exit without push” has been removed."
Ling from Google's firebase statement
https://firebase.google.com/docs/cloud-messaging/concept-options#setting-the-priority-of-a-message
Quoting;
High priority. FCM attempts to deliver high priority messages immediately, allowing the FCM service to wake a sleeping device when necessary and to run some limited processing (including very limited network access). High priority messages generally should result in user interaction with your app or its notifications. If FCM detects a pattern in which they don't, your messages may be de-prioritized. Android P introduced
app standby buckets which limit the number of FCM high priority messages you can send to your app that don't result in the user using your app or viewing a notification. If, in response to a high priority message, a notification is displayed in a way that is visible to the user, then your app standby bucket quota will not be consumed by that message.
You have alternatives,
1. Use V16 Update 5 by configuring Automatic Profiles or Manual Profiles as you wish from your WebClient or App.Explained here;
https://www.3cx.com/docs/android-app-faq/#h.lcteeu5yq5kd
2. Android 10 has a new feature "Digital Wellbeing"
https://wellbeing.google/tools/ named "Pause App", you can achieve this by pressing on the app long press. This basically will paused the app for the rest of the day. Using Android 10, this feature should satisfy your needs but I cannot guarantee that they come pre-installed
