Description (partial)

Symptom:
When SIP Publish is sent from a client application to the IM&P server, and for some reason home Presence Engine when user is assigned to responds with on of the following error message types: 2xx, 3xx, 412 and some other 4xx errors, the SIP proxy will resend the same SIP Publish message to the backup Presence Engine (in HA enabled pair). As a consequence, since user is not assigned to this IM&P node, backup Presence Engine will not be able to find the user and will send '404 Not Found' error back to the SIP proxy and to the originator/sender of the SIP Publish.

Conditions:
2 IM&P nodes in the cluster, with HA enabled. Custom SIP based client application is used for sending SIP Publish messages to the IM&P server.
