My users wants a directory wherein they will list all the numbers of their clients and when some client calls on their phone it should flash a name of that person. Same way we have a directory on mobiles. My Call manager is 18.104.22.168 with LDAP (Active Directory) integration for users + unity. Question is from where to create such kind of directory where i can put all the phone numbers or contact details. Right now internally this is working when some one calls to a phone their respective directory number and name display but i want this for external users.
