The metermaid-1.2.7.1.txt patch uses devicestate (AST_DEVICE_NOT_INUSE 
and AST_DEVICE_INUSE) and SIP subscribe/notify messages. If you can use 
hints to monitor the status of normal lines, then it should work for the 
parking slots too.

See the "Parking Lot Status / Access from the Programmable Buttons / 
LEDs" section at http://www.voip-info.org/wiki/view/Asterisk+phone+snom 
for the procedure for setting it up with Snom 360s. Maybe it will help 
with your Aastra too...

(The trunk code has something different apparently. I'm not sure where 
that is documented.)
