12.5(1.4) 12.6(2.2) 12.7(1.1) 12.8(2)

Description (partial)

Symptom:
When jabber is configured to use SIP URI for calls and when the cache expires, the cache refresh triggers SIP URI resolution for all the call history records.
If directory is configured as UDS, the cache refresh will send individual SIP URI resolution query for each record in the call history instead of using batch. 

If the users have a high number of call history records, multiple UDS queries are sent at the same time flooding the UDS. UDS MAX_REQUESTS is reached and starts sending a 503.

Conditions:
Jabber is using SIP URI for calls. 
UDS is used for contact resolution 
Number of records in Call history is high
