Hi all I have a couple of questions that I hope you guys can answer: I have to use radius for a prepaid solution. The soft switch is going to send radius authentication messages and accounting messages. My idea is to use FreeRADIUS with PostgreSQL. So my first question is if that's a good idea for a prepaid solution with real time billing involved to use these two? I will save both the accounting information and the user info in the postgreSQL database. But not all user info, mostly of it will be stored by the billing system, for instance the balance info. The user info in the postgre database is mainly used to route the user to the right billing base. Does the described solution seem to be a good one? Or should it be done differently? Another question is about authentication-request message. On the authentication-request I will get the following attributes: NAS-IP-Address Calling-Station-Id Called-Station-Id Service-Type Acct-Session-Id The attribute used for authentication is just the Calling-Station-Id. This gives a problem, the rlm_sql doesn't permit An Authentication Request without the User-Name and Password attributes. And as far as I can se there is Something that is hardcoded in the C code. If that is right I'll need to make the changes and recompile it? Or is there another solution on this? In the response to the the Authentication Request I have to send the calculated maximum call time Based on the Called-Station-Id and the user's balance. So before sending the response I have to execute something that calculates this. How can that be done in the best manner? Thanx /Erik
