asterisk users - Aug 2003 - h extension seems to wipe variables?

Hi.

I'm trying to do some custom call logging, and I want to call an AGI 
script from a hangup handler to log call durations and things. Although 
the script executes, it isn't retrieving variables from the AGI 
interface. Looking closer, I realised the variables are actually getting 
unset before the h extension is reached.

[foo]
s,1,SetVar,foo=bar
s,2,Play(audio/a-long-prompt)
h,1,AGI(log-call-duration.pl)

When I do an $agi->get_variable("foo") from the perl, I get the
string
"noresponse" returned.

This all works fine if I don't call the AGI from the hangup extension, 
but from a normal one instead.

Does anyone have any idea how I might fix or work around this? It's 
important for us to log call durations (and other things), which 
obviously needs to be done when the users hangs up. Storing stuff using 
the cdr isn't really an option.

Correct me if i'm wrong but doesn't the cdr modules log the call
duration?

Once the call has hungup the AGI functions stop working, so executing an
AGI from an h extension will not do what you expect.  but you can still do
all kinds of perl stuff there, so you could stick the info in mysql or
somewhere else

True, but in some cases you would want to do more. I have built IVR's that 
require some after-call handling. For this I tried to use variables as 
well, but failed. The solution in my case was to pass the variables from 
the extensions.conf and passing them as arguments to the AGI script rather 
then reading them inside the AGI script.
