I don't know if this has been discussed earlier but it would be nice
to point some key requirements for a system supporting prepaid users
and possible solutions to those requirements.
I think several of us is doing the same things so, we can benefit from
other experience and may be we can find a pattern (of course not
perfect and "fit all") for this problem using open source

I am talking about something like this:

- How to store and retrieve user category (postpaid, prepaid, etc).
LDAP, Radius, SER groups?

- Callflows

- What IVR to use for user notifications (no credit, etc) and user
balance check?
Asterisk, SEMS, etc?

- How to enforce call tear down when credit is exhausted?
What B2BUA to use?

- How to manage recharges?

Etc, etc.
