Hi all, I'm a newbie as well (ser + Linux). Yet, this is another prepaid implementation question. Some told to use Asterisk astcc for prepaid application, so i plan to set the card number as the authentication name. Thus, the original ser database has to customize for integration with astcc database (at least auth_db). Can somebody help me in this for necessary changes? Or any opportunity to look at working database structure? Second, should i handling prepaid and postpaid in one ser proxy? if yes, what is the best approach? Thank Regards Seong
