The Data administration application menu item allows you to manage the Lync data that is synced to the system.
Reassign Subnets and sites on calls:
This button is to be only used when changes have been made to the site and subnet allocations on Dossier so that all the old call data can be re-allocated the new site and subnet allocations.
Once the job has started, the server will take some time to go through all the data in its database and re-allocate them. Please be patient.
