[Freeswitch-users] System global mode variable

[Pete Ashdown]

Answered my own question:

In your dialplan:
<action application="lua" data="script.lua"/>

In script.lua:
mode = freeswitch.getGlobalVariable("mode")
if (mode == "open") then
  session:speak("open")
end
if (mode == "techonly") then
  session:speak("teck only")
end
if (mode == "event") then
  session:speak("event")
else
  session:speak("i dont know")
end

Make sure the global is created somewhere, like vars.xml:
<X-PRE-PROCESS cmd="set" data="mode=open"/>
