Hello, I am using freeradius 1.0.1 to authenticate users for a voip gateway.
Suppose voip gateway A wants to make a call to voip gateway B. In order to authenticate A,the calling number,the details of user A has to be listed in the users file. Similarly if user B , the called number also needs to be authenticated , then user B details also need to be in the users file. 1. What authentication mechanism need s to be used ? 2. Can B also get authenticated at the local end, before even sending setup message to B ? 3. If the above application is for prepaid / postpaid then how is the credit amount left or the call duration details obtained from the radius server ? Is there any specific attribute that has to be sent either in access request or accounting request due to which the radius server would get an indication to send the details in the respective response packets ? 4. If radius server is used just to authenticate the calling number and is not bothered to know about the credit amount and the duration, then the radius server shoud not send any such details in the resposne packets. 5. Is there any configuration to be done in the radius server so that it could manage the users accounting details for billing or prepaid or post paid authentication ?
