Current calls are visible in CPM Monitoring, which has no export function. A screen-shot can be taken for reference, but is is not possible to export data regarding current calls.
Once call data is visible in CPM Analytics, then it can be exported for further analysis - see How do I create a report in Vyopta?
An API for CPM Monitoring is available upon request, that will allow access to real-time data. Please see The CPM Monitoring Query API
