Here is a new proposal for emergency calls handling.
Steps in handling emergency calls:
- subscribe to modem online notifications (add modem online watcher)
- an emergency call detected (phone number is emergency number)
- increment emergency mode
- advertise "EmergencyMode" property change on D-Bus (first call)
- set modem online if it's in offline mode (minimal setup)
- adevertise "Online" property change on D-Bus
- if modem is not online postpone making the call, otherwise make
the emergency call
- when modem online notification comes and there is postponed call request
make the emergency call
- when an emergency call ends decrement emergency mode
- set modem offline if it was set online due to the emergency call (last call)
- advertise "Online" property change on D-Bus
- advertise "EmergencyMode" property change on D-Bus (last call)
Note: emergency calls with SIM card (network registered or unregistered) and
without SIM card are supported.
