All the users unable to acess the directory service,when i press the directory button in the phone it shows host not found,i have verified all the basic settings in cucm!!!
Now i made in service parmaterd prepare roll back cluster 8.0 make it false & rested all the phones now able to acess the directory,,,suresh we have done a upgradation.
Interesting. If the rollback procedure worked then the TVS itself wasn't broken. The phones wouldn't have accepted the null-length but digitally signed ITL file had the TFTP certificate continuity been broken. Your tomcat certificate must be missing from the tvs-trust store. You should read up on this in the CUCM Security Guide so you understand the mechanics of what is going on here.
Thanks Jonathan,i will go through the document,you are making me easier to understand.
+10 for you.
