Billing

This is a project by AviMarcus to manage billing for VoIP.

=My use:= I have no billing mechanism of any kind. This will have to be the whole thing.


 * 1) Bill various monthly and per-minute charges.
 * 2) Bill residential users a flat monthly fee, optionally a monthly per-DID fee, and per-minute, as set in the dialplan handled by mod_nibblebill.
 * 3) Bill business in a multi-tenant manner. Flat fee for PBX hosting/support and flat fee for trunks (if through me) or per-minute, again as per mod_nibblill.
 * 4) This should integrate with paypal, which allows variable recurring. It's free until 2011 then only $20/year.
 * 5) Trigger paypal payments on a low balance threshold.
 * 6) It should provide a payment/balance trail and list the CDRs and the prices of whatever they were billed. Also, let me restrict outgoing calls for no balance.
 * 7) I would like integration with DIDWW API, so users can choose to add a new DID and it gets added to their monthly charges and gets automatically routed to their extension (personal) or where they want (business)
 * 8) Perhaps - users, or atleast the admin, should be able to cancel monthly charges - but to be completed at the end of the month.
 * 9) Since the monthly charges are stored in a DB, then we should be able to dynamically check from the dial plan if someone has a certain service enabled or not.
