Hello ! 1. How to implement using different SQL modules for different huntgroups? Something like this(?): authorize { Huntgroup card { sql_module_card #first instance } Huntgoup contract { sql_module_contract #second instance } } We're going to use CiscoAS53 as access server for contract clients (they use billing based on PostgreSQL) and for prepaid card clients (they use remote Oracle DB server), so we need absolutely different techniques for auth&acct for this groups of clients. 2. How to specify huntgoups, if the groups will have a same NAS-IP-Address? They even possibly will have the same Called-Station-Id... Can I use regular expression to make difference between this two groups? The cards group will have exact 14 digits in the User-Password attribute, so it's not hard to identify such users... Or I even can reserve some User-Name for the users in 'card' group, so different users will only vary on User-Password (they'll enter their pin-code here). Thanks a lot for any comments. If it's not possible to split this groups of users into different groups, we have to configure up another access number in CiscoAS, and confugure two radius-servers, and say to end-users to use phone number1 if they have contract with login/password or phone number2, if they use prepaid card... :/ -- Ruslan A Dautkhanov
