[asterisk-users] Billing Software

[lists at infoway.net]

We are looking for an offline billing solution. We have a couple of
particular requirements:

1) Since it's offline, we need to be able to import the CDR.
2) A way to support account credits based on referrals. Meaning, that if a
member refers a new account, that member would get a free month of
service, or similar type credits.
3) Generate invoices in either HTML or PDF format so they can be printed
or emailed to the actual customers.

Does anyone know of a package that supports this? Would prefer open source.

Thanks,
Daniel
