Dear frindes, i would to like to have all of users data in mysql db and autenticate user(for registeration) thru standard Radius interface e.g. FreeRadius, meaning when SIP user send REGISTRATION to FS, FS will send Radius request to FreeRadius, then FS auth user OK or NOK according to the response from FreeRadius. i read the wiki, there are some modules related, e.g. Mod_rad_auth, Mod_xml_radius, Mod_radius_cdr, however, no one provides a definite example for my case, could anyone help advise an example or any hint how to make it done, BTW, i can thought about using mod_xml_curl, however i don't want to use it if there is a better one. Thanks! Regards, Charles
