Integration with Smarsh archiving is a feature of Brosix Enterprise.
You will need to have an account with Smarsh to receive the Chat history from Brosix. Then go to Web Control Panel -> Settings -> Integrations tab. Find the “Smarsh Archiving” section and activate the feature.
Once activated, this feature will automatically transfer all your Chat History to Smarsh. Records will still be available on Brosix servers for your review and you will still be able to download the monthly archives from Brosix Control Panel.
