whats happening on this front? having your mobile phone use the gprs service to make voice over ip to another client? ok, how would the 2 phones be identified? how would the calling phone determine where the target phone is? could a intermediate server be involved where the interested parties are logged on? could the phone imei number be used to identify the parties?
more reading on the topic leads to the news from vonage, the voip pioneer, about announcing their voip mobile phone f1000 in u.s.. its targeted use is being used at hotspots which are scarce in themselves at this time, so the phone would be mostly used at home installations with vonage connections.
