We need some programming on the Asterisk PBX to work in the hospitality market:
- Calls billing (maybe through integration with A2billing)
- Wake-up call
- Notification of wake-up call
- Room status (change the room status dialing a code in the telephone)
- Notification if the client dials the emergency number
- Check-in/out (enable/disable external calls)
Preferable, it should be integrated with PostgreSQL database.
