Ok.  I still have some problems with this.  My dialplan contains the
following:

<action application="export" data="session_in_hangup_hook=true"/>
<action application="export" data="api_hangup_hook=luarun
transfer_check.lua ${uuid}"/>

The transfer_check.lua script is the following:

session = freeswitch.Session(argv[1])
local cause = session:hangupCause()

if cause == "ATTENDED_TRANSFER" or cause == "BLIND_TRANSFER"
then
    api = freeswitch.API()
    api.execute("log",  "NOTICE Transfer detected, billsec is " ..
session:getVariable("billsec"))
end

The problem is that, as already discussed, the channel no longer exists
so the UUID is not referring to anything.

Basically, my question is: How do you obtain the session object in a
hangup hook?

Cheers.
