<div><font face="Arial" size="2">Wi-Fi SIP phones aren't limited to
hot spots. I am in the process of setting up asterisk for SOHO. At
present I'm not even using VoIP trunking, only LAN to stns and I intend
to use Wi-Fi instead of analog cordless phone. I got the Engenius one,
and it works, but I haven't played with it much. I was disappointed
that it only has a single line appearance, as part of my reason for
going SIP was to allow the same features like say my 941. I also got
their 600 mw access point, but haven't had time to try it. My goal is
to cover out 3 acre property and the 1/2 mile road to the mailbox,
including mountainous terrain. Maybe I'll share more when I actually
get it all put together.</font></div>

I think you will get better range and longer battery life from a DECT
phone though... Probably more features and better quality also!<br>
<br>
Any of the panasonic DECT phones seem to work very nicely (speaker
phone, features, "R" key works for call transfer, handset intercom etc
- mine lasts up to a week on a single charge and light use) and there
are several Siemens DECT phones with a builtin SIP gateway which avoids
the need for an external adaptor box<br>
<br>
It's definitely possible to make wifi work for half a mile and you
don't even need a 600mw transmitter to do that - however, wifi is all
about receive strength, and so you are unlikely to get a significantly
better coverage with a high power hotspot which is suboptimally
placed. If you do go that route then getting the antennas into a
location where 90% of the signal isn't already killed going through
walls before it has to travel some distance is the trick. Probably
also consider a repeater of some sort rather than just one high power
device<br>
<br>
Good luck though!<br>
