Call Detail Recording (CDR) records usage information about instant message conversations and meetings. Some organizations use the usage data obtained from call detail records (CDRs) to calculate their return on investment (ROI).
You can record the following usage information:
Peer-to-peer call details. Details of all peer-to-peer
sessions, including Voice over IP (VoIP)-to-VoIP calls, instant
messaging (IM), audio/video(A/V), file transfer, application
sharing, and remote assistance sessions.
Conferencing call details. Details of all multi-party
sessions, including instant messaging and audio/video sessions, and
details of all conferencing sessions conducted using the Office
Live Meeting client.
Voice call details. Details of VoIP-to-public switched
telephone network (PSTN) calls.
For details, see in the Planning and Architecture documentation.
Use the following procedure to enable call detail recording in your organization. You may have already done this when deploying Monitoring Server.
After call detail recording is enabled in the forest, you must enable it on each pool to be monitored, and associate the servers in that pool with a Monitoring Server. For details, see Configuring Associations with Pools and Mediation Servers.
