Description (partial)

Symptom:
For configurations where "Line Appearance Association for Presence" is enabled for Jabber users on CUCM, a situation may arise where the Jabber user is in Available state, yet the Jabber device on CUCM is in DND state (unable to receive calls).  

This lack of synchronization can be caused by a race condition in how Presence Engine handles DND state between Jabber clients and CUCM.

Conditions:
- "Line Appearance Association for Presence" is enabled on CUCM's End User page for Jabber devices
- Timing issue where status update comes from Jabber and CUCM around the same time
