ISDN info: uui and msisdn

Hi all, my name is Roberto and I have a question… how can i read uui (user to user information) and msisdn (caller id) from an incoming isdn call (I have a pri isdn)?

I’ve read that asterisk can handle these infos, someone says that asterisk need to be recompiled with set USERUSERINFO flag into chan_dahdi.c… I tryed this but it doesn’t work!

I think that these infos comes into the d-channel, but i tryed to debug d-channel and I can’t read these informations… I’ve tryed many ways, but nothing that works for me…

(sorry for my english… hope someone can help me)

Roberto

up, please help me guys!
