For wifi roaming to work you need to have all AP use the same BSSID and make
sure they all pass dhcp querries from the phone (or other wifi devices) to a
single dhcp server.
Even "dumm" wifi devices can work like this, as there is no need to changed
the BSSID and the dns makes sure that the device gets the same ip regardless
of where it registers.
We used this method in several large construction sites where the engineers
where rooaming using their pda's

I tried to use a wifi wireless phone, but I ran in to problems with the
access points, when you move from one access point to the next one, the
signal was lost and the handset was not smart enough to to locate the next
access point with out asking the hand set to recalibrate to the new ip
address on the access-point, i was interested in using this for a nurse call
system, has any thing change, and is there a way to use the wifi service to
find hand sets, thanks (wifi,sip,wireless-phones,)

I didn't realize he was trying to do local area etc but was looking for
roaming capabilities across wider area.
If you are just looking for onsite paging then a Nira/Ascom box
connected to a server will do what you want though only on a specific
site (lol takes me back - first IT sales job was with Nira but working
on their CT3/Dect systems).

POCSAG encoding software and small vhf transmittter (walkie talkie)
will work. Then you can use "normal" pagers.
