Re: [asterisk-users] [OT] wi-fi ip phone scenario
Yes, same channel and same ESSID for all AP's. Are you connecting each AP to the LAN? Or only one connected, and the others as relay? With WDS, you have to keep same channel and ESSID for a good roaming. If connected to the lan, doing it worked really good for me, roaming was working in the same way as with WDS (no latency).

Re: [asterisk-users] [OT] wi-fi ip phone scenario
You might check with Aastra, they are showing a DECT phone that will work with Asterisk via sip. I know the release is next year for me, but since you are in Europe it may be avaliable sooner.
