Suppose I have Lua script which do api:executeString("originate {api_hangup_hook='lua hook.lua'}user/100,user/101 &echo") I need execute `lua hook.lua` only once when entire `originate` was finished. Problem that hangup_hook called twice (once for each channel). Is threr any way to know in hangup_hook that this is last one. Or is there any other way to do this. My Lua script should be able create several sessions (originate) like while ... do api:executeString("originate ...") end So I do not think I can create freeswitch.Session. Also I do not like use `loobpack` and do originate via loopback to Lua application and manage session there.
