By default, call detail recording (CDR) data is purged after 60 days. You can use the settings on the Call Detail Recording page to retain the data for a longer or shorter period of time. If you disable CDR, data that was captured before CDR was enabled will also be subject to purging.

You should configure CDR and Quality of Experience (QoE) to retain data for the same number of days. Each call in the call detail reports (CDRs), available from the Monitoring Server Reports webpage, includes CDR and QoE information. If the purging duration for CDR and QoE is different, some calls might only include CDR data, while other may only include QoE data.

The following procedure describes how to configure purge settings CDR data.

To specify retention of CDR data

  1. From a user account that is a member of the RTCUniversalServerAdmins group (or has equivalent user rights), or assigned to the CsServerAdministrator or CsAdministrator role, log on to any computer that is in the network in which you deployed Lync Server 2010.

  2. Open a browser window, and then enter the Admin URL to open the Lync Server Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server Administrative Tools.

  3. In the left navigation bar, click Monitoring and Archiving, and then click Call Detail Recording.

  4. On the Call Detail Recording page, click the appropriate site in the table, click Edit, and then click Show Details.

  5. To turn on purging, select Enable Purging for Monitoring Servers.

  6. In Keep call detail recordings for maximum duration (days): select the maximum number of days that call detail recordings should be retained.

  7. In Keep error report data for maximum duration (days): select the maximum number of days that error reports should be retained.

  8. Click Commit.
