I concur with Michael, the current crop of WIFI phones on the market do 
have their individual quirks, and you will likely encounter issues using 
consumer grade access points.  If you have some money to throw at this, 
and want a real slick, industrial grade solution that will integrate 
with SIP, I would recommend you check out the Durafon 1X or Durafon 4X 
from Engenius.  We have seen these implemented and SIP enabled using 
your garden variety ATA or FXS gateway.  These are not WIFI phones, they 
use conventional Digital spread spectrum with frequency hopping, and 
have a very cool, full duplex 2 way radio function as well.  The 
handsets are bulletproof as well, very rugged and well designed.

These were designed for relatively "extreme" environments, and they work 
very well, but are not inexpensive.
