How we are able to access to the session variables inside lua file which is executed by api_hangup_hook
Currently i have something like
<action application="set" data="session_in_hangup_hook=true"/>
<action application="export" data="nolocal:api_hangup_hook=lua hangup_file.lua"/>
That will execute "hangup_file.lua" when leg_b hangsup. Is there any kind of possibility to access to the session variables of leg_a or leg_b session within that hangup file?
What ever i try, I am getting an error "attempt to index global 'session' (a nil value)".
If its not possible to achieve this for what is the purpose of "session_in_hangup_hook=true"?
The wiki shows that you actually have an env object (but it doesn't mention if this comes from session_in_hangup_hook).
