    Hi,
     
    Recently got our sysadmin to build some webeservers and deploy the IP phone service SDK so we can query our AD and use the service as the CUCM Corp Directory. Issue im seeing is when access the new Corp Directory from a phone  the delta time from the GET /LocalizedDirectory/Corporatedirectory.asp to the HTTP OK is approx 3sec's.
     
    Subsequent access to the directory is sub second. If dont use for a few hours get the initial delay again.  At a TCP level RTT is <1ms.
     
    As any one else come across this, or any ideas where issue may be?
     
    Thanks
