The CDRs (Call Detail Records) are first stored on the local hard drive and are then pushed to or pulled from a billing server (for example, Lotus Sametime Unified Telephony Accounting Management or third party billing application) which post-processes the CDRs.
All CDRs are stored in flat files. You can configure both a primary and secondary node for CDR storage and you can explicitly select one of the CDR delivery methods (Push or Pull).
After they are pushed to the billing server, the files can be:
Saved, then automatically deleted after a specified retention period
Saved until the administrator manually deletes them.
If both. primary and secondary node, fail or in case of an ftp failure, the ticket files will remain in the ticket pool. Ticket pool means the /tpa/CDR loation where the tickets will remain until the link to the primary or the backup billing servers is restored.
