[Freeswitch-users] can't get channel variables after hangup

[Michael Collins]

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...
