Use the CDR output to port 9002 or 9003. That’s the only way I know. You have Incoming Line and Incoming Channel. For PBX the Incoming Line is 1, and the Incoming Channel is the number of the PBX port (cabin). Just write a simple script that connects to that port on the Quintum and inserts all the data to a database in real time. The rest is easy – software that will take the info from the database, compare the dialed number with the rate table, and display the result. I think it’s a very simple solution, and you don’t need Radius server at all.
You know how to contact me if you have any questions :).
