Cdr.conf - (unanswered =yes) making no effect

Hello All,

I was configuring asterisk-1.4.21.2 version in PRI line with Sangoma card.
All the things got working properly and I made a sample IVR menu and it also got worked fine.

But still no effect the only last application data is recorded in to the DB.What i need is the entire data the whole tree where the user had gone through.
Can anyone can lighten up me here.

Thanks,
Bipin
