Thanks for your response. I've done some further testing and what I am experiencing with 9.2.1 client is.
1. I change telephone field in AD to new phone number.
2. I run a wireshark instance on my PC, with Jabber client.
3. In Jabber client, I do search on user who I just changed phone number.
4. Do view profile and it is still showing old details.
Now when I check the wireshark trace I can see the LDAP query from my PC to LDAP server and the response from LDAP server to my Jabber username search shows the new phone number just changed in the packet.
Therefore the Jabber client is searching the LDAP correctly and LDAP is sending the correct information, but Jabber client not updating the user details.
Last note if I shut the Jabber client and reopen, the new phone number will populate the user.
If anyone can do a test to see if they have the same experience with 9.2.1 client, just change a phone number in AD, and then do search on user and see if new number replicates.
I'm sure with previous versions it happened instantaneously???
