I've got a cisco unified call manager 6.x, and whilst for internal calls I'm getting a display of a display name on our phones (7941G/7961G), for external calls (where caller-id is presented), no display name is there - even for numbers which are in the corporate address book.
We're using phone mobility, and linking phone authentication through LDAP/AD, and corporate address book through our LDAP/AD.
Is my expectation that it's going to look up caller-id via the corporate address book right? Where else would it look it up? Is there a way to add in display names for external caller-id other than this?
I've looked through Cisco's website, Google and other resources without much help so far. Any assistance would be appreciated!
