Ashutosh, thanks for the info.. some more related queries.. > what did u'll use for session control..

Considering tpically 802.11 end-point device (phone/ or a lap top with a 802.11 WLAN card).. trying to call another end-point SIP based IP-phone which is on the LAN. The intermediate RF interface will be between the 802.11 compative mobile device and Access Point, through with frames will be tunneled. Data access is typically not an issue. But for voice, does the same setup suffice or would any other external component (h/w , s/w) be required for this. I presume QoS will still be an issue, but that is still ok for now..
