Archiving and CDR

Communications Server 2007

The Microsoft® Office Communications Server 2007 Archiving and CDR Server provides a solution for archiving instant messaging (IM) conversations and group conferences, and for capturing usage information related to file transfers, audio/video (A/V) conversations, application sharing, remote assistance, meetings, and conferencing servers in call detail records. The Archiving and CDR Server can archive all instant messaging (IM) conversations for all users or for individual users that you specify. The Archiving and CDR Server can also archive call detail records for all users.

Messages from each Office Communications Server configured for archiving are sent through the Windows Server® Message Queuing service to the Archiving and CDR Server, which uses a Microsoft SQL Server® database to store archived information.

Although the archiving and CDR agent is automatically installed as part of the core Office Communications Server process, in order to archive IM traffic and call data, you must configure the archiving and CDR agent, as well as install the Archiving and CDR Server to which the archiving and CDR agent connects. Archiving and CDR enable Office Communications Server to archive all instant messaging (IM) conversations for all users or for individual users that you specify, as well as archive call detail records for all users.

The Archiving and CDR Server consists of three components:

  • Destination queue, which is managed by Microsoft Message Queuing
  • Archiving and CDR Service component
  • Archiving back-end database

The Archiving and CDR Service component can reside on the same computer as the archiving database or it can connect to a database on a different computer. Figure 9 shows the archiving architecture in Office Communications Server 2007.
