Hi list, are there alternatives to Radius for billing integration with OpenSER? The problem Radius seems to pose me is that it is per user and therefore requires to have a full database of every softphone/SNOM/etc user, which is admin intensive. Does anyone know if there is a method of accounting data per SIP peer (for example per Asterisk system attached to OpenSER) which could record call details without needing to know about all the actual handset users? I suppose you can do anything you want with the accounting module so this is really a "does anyone already do this" question so I dont need to invent everything from scratch... thanks for any suggestions, Andy.
