[Freeswitch-users] LUA getVariable

Hello, I have one LUA script that make calls to one custom FS app. That app sets up some session channel variables and makes an outgoing call: if(caller_channel = switch_core_session_get_channel(session)){ switch_channel_set_variable(caller_channel, "var", "val") } If the caller hangs up the call, the app returns and I try to get the val of var as: session:getVariable("var") but a nil value is returned. Do you know why? Regards
