Hm. I've just bought an M3 set for a client, but the range isn't anywhere 
near as good as the Siemens I've been using...

and re. the Siemens - I had that issue with the older C460IP phones - my 
solution for clients was to sell them with a cheap (£5) wall timer 
programmed to kill the power at 4am and come on again at 4:15. (the cheap 
dial ones only have a 15-minute resolution!)
