What simple billing for Asterisk do you use?

Question

MySQL

I'm looking for a simple free billing option for asterisk:
- accounts
- balance
- integration with MySQL (optional)
Tried asteriskCC; a2billing. Both options are too loaded with superfluous, and have not yet been able to connect them to the asterisk configuration (do not start users, trunks). I don’t see the point in dealing with one of them, because judging by the web interface, it’s not quite right.

Answer 1

I have not used it yet, but I only know of free ones - ubilling.net.ua
