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!
External Caller ID is probably coming from the provider. First you may have to request that your providor sends you that information. For Qwest I had to submit a special request for "Caller ID Name Delivery."
If you're past that step the next thing to do is telnet to the gateway and do a "debug isdn q931" and "ter mon" When a call comes in you should see something like the following.

CUCM does not currently do Number to Name resolution for external (i.e., ingress PSTN) calls. So, you're likely looking at a script or some sort of application (which is really just a series of expensive scripts with a fancier interface) to accomplish this. I don't have any alternatives to give you but can certainly answer your question about the CUCM's capabilities.
