I use ser+radius to do authentication, this way I can disable users or 
groups of users in a "standard" way, without using tricks like changing 
passwords.
(when your customer pays he expect to have the same password as before, 
have you saved it ? where ? in a safe way ?)
radius has a mysql backend, so also no need to reload config files.
Asterisk and radius share the same db, with some not-too-complex agi 
before the actual Dial you can do stuff like setting the call timeout 
based on the remaining credit, blocking the call if the credit is too 
much in the red, and so on...
