Yeah the 480i-CT is a nice product, and not subject to the
inconsistencies of WIFI. What impressed me about the Engenius handsets
was the range. 250,000 square feet coverage, or 3,000 acre coverage in
an outdoor application, off a single radio AP, that's a large footprint.

FWIW, the cordless handsets on the Aastra 480i CT work well. I've waled
about while on a call, to a distahce of approx 300 feet before the call
quality started to suffer. The phone supports up to 8 (I think)
handsets, treating each as a separate extension. It can page between
handsets without involving Asterisk. It supports up to 9 line
appearances, which means that all the cordless and the base units can
be on a call at one time.
The only thing that I hated about the Engenius phones was the fact that
they didn't support a plain 2.5mm connector for a headset.
The 480i CT is pretty awesome.

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.

This is only slightly related to Asterisk (in that we are using
Asterisk as our PBX),
so feel free to contact me off-list.
I need to hear from someone who has practical experience using the combo of
Asterisk, WiFi, and WiFi VOIP phones like the Hitachi-Cable IPC-5000.
In particular, I need to know if scattering consumer grade access
points (Linksys,
D-Link) throughout a warehouse is going to be satisfactory, or if we
should use some
kind of mesh access point from Orinoco or Strix. (In hopes of a better handoff.)
I tried using the consumer access points (Linksys WAP-54G) and had not
end of troubles. Firstly, they all have to have the same SSID or not
hand-off at all. Secondly, I found that the WLAN bandwidth would
occasionally just go away for a few seconds, which caused calls to
simply go silent for 3-4 seconds unexpectedly. Never long enough to
drop the call...but enough to force me to ask the other person to
repeat themselves. Lastly, the volume level presented by the WIP-5000
was never enough for my tastes.
I found that the range around each access point was very limited. Bear
in mind that consumer access points often don't put out the full
allowable RF power. If you use third party firmware hacks to up the RF
output you'll find that they start to through a lot of spurious
interference as well. Not the best quality radios I guess.
I eventually switched to using a Astra 480i CT desk phone with a couple
of corless handsets. It's been great.
