PRI billing signalization

My local telephone provider on PRI lines gives billing signaling. Is there any way to use this signalization? I would like to store those informations in database (MySQL). Has anybode done something similar? So far I have export CDR that Asterisk generates, in MySQL. Those information I’ll will use for doubl check of CDR and billing.

Any informations are welcome.

What is billing signaling?

yea i have never heard of this unless your talking about doing some ss7 type stuff.

I don’t know, maybe we are talking about same stuff. What I ment is that my Telco gives some sort of signalization (od D channel) which (if I’m able to “read” it properly) can tell me how much the call has cost me.

Is that ss7?
