Data Retention

It is now possible to configure a data retention policy for different types of historical data, then they are automatically archived on file system and removed from operational database. Administrator can dis/enable data archival and configure the retention period to keep historical data online. Archived data can be exported/downloaded and removed from PrivateServer.

This version enables by default 1 month of data retention for SIP Sessions data, which are generally useful only for debugging and support purposes: if you want more, please change configuration.
