Monitoring ZAP channels with Snom 360

recieved a snom 360 today for testing, i know you can monitor extensions so when there in use the led lights up. Does anyone know how to monitor a zap channel so when its in use it lights the LED? And when Asterisk recieves and incoming call on the Zap channels you can press the zap LED to answer the call. Any help would be greatly appreciaited, thanks.
