I am trying to configure CUCM 6.1 with CUPS 6.0. After the initial configuration i can login to CUPC, but i cant change any options there. I cant change the mode to deskphone or soft phone. It is not giving me any function other than login. I havent got any LDAP connection, could someone tell me that presence needs LDAP connectivity, if not could someone help me to figure out what is missing in my configuration.
