We are evaluating if one of our AAEP Applications can trigger different event handlers on a component failure. The condition would be based on the DNIS number the call was received on. We are looking for advise on this task but we are also curious to know if there is any documentation on the exit namelist elements (avayaExitReason, avayaExitInfo1, avayaExitInfo2, avayaExitInfo5, avayaExitInfo6, avayaExitInfo7, avayaExitInfo8, avayaExitInfo9, avayaExitPreferredPath, avayaExitCustomerId, avayaExitTopic). How are they set and what values might they contain?

The exit reason and info fields are actually designed to be set by the application. These are fields in the session variable you can leverage. You can set these field during the execution of the app and they will get written to the detail reports.
