Actually - er - a-ha - indeed... However the GSM part if it all is sort of 
unavoidable !!! But I'd rather have a wire going from an asterisk box to a 
phone device than use an additional wireless connection... I'm not sure 
I'd get away with installing a box in a customers permises, then plug in a 
USB/Bluetooth dongle, and then just leave a mobile-phone cable-tied to the 
rack... At home/lab, sure. It's fun and neat, but not in the office where 
even a USB cable from the server to the phone might be frowned upon. (The 
phone would get nicked!)

Cheers,

Gordon
