I also tried the one recommended by Cisco support by the way: 11.3.1MSR1.3 Same issue, even with the change to Search Item 3:    NumberSearch Item 3 Filter:    telephoneNumber

Thanks Adam, that's the first thing I tried, current firmware I have upgraded to is: sip8845_65.11-3-1MPP-697.loads Is there another one I can try?

Thank you very much for your help, I tried: Search item 3: NumberSearch Item 3 Filter:telephoneNumber But the issue persists. I can call contacts that are on the LDAP directory and it shows the contact name when I call them, but on incoming calls, it...

Thank you, I tried that firmware and I'm still having the same problem.Neither XSI or LDAP contact names are recognised on incoming calls.Is this a known issue or am I the only one?

We have the same problem incoming caller id id names are not showing on our XSI, LDAP, or XML directories.  I'm happy if this works on LDAP or XSI.  I'm currently testing on an 8865 with this firmware: sip8845_65.11-2-1MES-3.loads How can I fix?
