I want to talk between two mobile phones (over SIP) out in the nowhere (where I cant use normal phone call) with bluetooth headset and Direct Wifi (hopefully over 100meters) between two or more phones! I cant understand why its so complicated! OK I don't need SIP but full duplex without click on the mobile when talking.

So how can I make an app for that? '
Maybe I need both a serverapp and a client app. Or maybe an already made app as server.

Please give me some idear!
