Hi Daniel-Constantin
about radius again: we need interact with radius same way:
1. when receive sip message with REGISTER method - initiate auth with radius. (Authentification)
2. when receive INVITE message - ask radius 'bout permissions and parse answer: get permission and next hop IP. (Authorization)
3. when call a) before call send Acct-Status-Type = Start with attributes. b) after call send Acct-Status-Type = Stop with attributes. (Accounting)
As I understand no problem with 1, 3b. Are 2, 3a possible?
