Hi Jamie, 

What we have done is add these lines in the dialplan:

<action application="set" data="session_in_hangup_hook=true"/>
<action application="set" data="api_hangup_hook=lua myscript.lua"/>

Then in <FSROOT>/scripts/myscript.lua:

cdr_uuid = session:getVariable("cdr_uuid");

This is on a FreeSWITCH 1.2 box. Hope this helps.

regards,
David

Hello,

I¹m trying to use the Hook event¹s with LUA script¹s when the channel Hangup
a call,
but I¹m unable to get the variables, for example uuid, ani or billed seconds
for the call,
I¹m using freeswitch 1.4.13 on Centos 6.6 and my configuration is:

In /autoload_configs/lua.conf.xml
[]
    <hook event="CHANNEL_HANGUP_COMPLETE" script="catch-event-cdr1.lua"/>

In my catch-event-cdr1.lua script I wrote:
    ses = freeswitch.Session();
    my_uuid = ses:getVariable("uuid");
    freeswitch.consoleLog("notice","    uuid=("..my_uuid..")\n")

But I¹m get the following error:
    2014-12-15 23:51:46.100755 [ERR] switch_cpp.cpp:724 session is not
initalized
    2014-12-15 23:51:46.100755 [NOTICE] switch_cpp.cpp:1328     uuid=()

Also, in the wiki doc I see a reference for the ³env² Object,
(https://wiki.freeswitch.org/wiki/Mod_lua#Special_Case:_env_object) but if I
call it as the example in the same lua script my result is:

How I call the env variable:
    dat = env:serialize()
    freeswitch.consoleLog("INFO","Here's everything:\n" .. dat .. "\n²)

And I got the following error:
    2014-12-16 00:00:17.440782 [ERR] mod_lua.cpp:203
/usr/share/freeswitch/scripts/catch-event-reg6.lua:27: attempt to index
global 'env' (a nil value)

Your help will be appreciated.
