abstract fun onCallDisconnectCauseChanged(
    disconnectCause: Int, 
    preciseDisconnectCause: Int
): Unit

Callback invoked when call disconnect cause changes on the registered subscription. Note, the registration subscription ID comes from TelephonyManager object which registers TelephonyCallback by TelephonyManager.registerTelephonyCallback(Executor, TelephonyCallback). If this TelephonyManager object was created with TelephonyManager.createForSubscriptionId(int), then the callback applies to the subscription ID. Otherwise, this callback applies to SubscriptionManager.getDefaultSubscriptionId().
Requires android.Manifest.permission#READ_PRECISE_PHONE_STATE
