This is demonstrated in the Asterisk SCF project during a demo, check youtube.so, i see they made the asterisk server fail over by unplugging a node and that's cool but not what i need. what i want is a way to keep a connection with an asterisk server (or any other preferably free voip server) when one path fails. this wouldn't be an issue if i could garante a sip gateway at each ap (wifi or 3g). ... or did i miss something?
