  This won't work. The "session_in_hangup_hook" literally means that the $session object is available in the hangup hook script. You need to use Lua, Perl, or Javascript to access the $session object. What you are doing is actually trying to access a uuid that does not exist. Once the call is over it's gone. The "session" object will be available only in the script that is called in the hangup hook. 

  Here's a simple script you can tinker with:
  -- hook-test.lua                                                                                                                                                
  dat = env:serialize()                                                                                                                                           
  --freeswitch.consoleLog("INFO","Here you go:\n" .. dat .. "\nn")                                                                                                

  uuid = env:getHeader("uuid")                                                                                                                                    
  freeswitch.consoleLog("INFO","Inside hangup hook, uuid is: " .. dat .. "\n")                                                                                    

  my_var = env:getHeader("my_custom_var")                                                                                                                         
  freeswitch.consoleLog("INFO","my_custom_var is '" .. dat .. "'\n")                                                                                              

  api = freeswitch.API()                                                                                                                                          
  res = api:execute("uuid_dump",uuid)                                                                                                                             
  freeswitch.consoleLog("INFO","result of 'uuid_dump " .. uuid .. "' is:\n" .. res .. "\n\n")                                                                     

  Hopefully that will illustrate the issue...

    I set this in my dialplan :

       <action application="set" data="session_in_hangup_hook=true"/>
       <action application="set" data="api_hangup_hook=system /usr/local/bin/php /usr/local/freeswitch/scripts/php/test.php ${uuid}"/>

      and this in test.php:

      exec("/usr/local/freeswitch/bin/fs_cli -x \"uuid_getvar ".$argv[1]."  test_var\"", $exTabRet, $req);

     it results :

    -ERR No Such Channel!

    I tried to replace ${uuid} by ${call_uuid} without success.

    Thanks
