[Asterisk-Users] h extension seems to wipe variables?

[Alastair Maw]

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.
