Information About Directory Services
Cisco Unified CME automatically creates a local phone directory containing the telephone numbers that are assigned in the directory number configuration of the phone. You can make additional entries to the local directory in telephony services configuration mode. Additional entries can be nonlocal numbers such as telephone numbers on other Cisco Unified CME systems used by your company.
When a phone user selects themenu, the phone displays a search page from Unified CME. After a user enters the search information, the phone sends the information to Cisco Unified CME, which searches for the requested number or name pattern in the directory number configuration and sends the response back to the phone, which displays the matched results. The phone can display up to 32 directory entries. If a search results in more than 32 entries, the phone displays an error message and the user must refine the search criteria to narrow the results.
The order of the names in the directory entries is first-name-first or last-name-first. Character strings for directory names can contain a spaces and a comma (,) and cannot contain an ampersand (&).
The local directory that is displayed on an IP phone is an XML page that is accessed through HTTP without password protection. The directory HTTP service can be disabled to suppress the availability of the local directory.
For configuration information, see Configure Local Directory Service.
From CME 12.0 onwards, an optional username and password can be configured for authenticating the local directory services.
For more information on the CLI command service local-directoryauthenticateusername password , see Cisco Unified Communications Manager Express Command Reference.
Cisco Unified IP Phones can support URLs in association with the four programmable feature buttons on IP phones, including the Directories button. Operation of these services is determined by the Cisco Unified IP phone capabilities and the content of the referenced URL. Provisioning the directory URL to select an external directory resource disables the Cisco Unified CME local directory service.
When phone agents answer calls for different departments or people, it is often helpful for them to see a display of the name, rather than the number of the called party. The Dialed Number Identification Service (or Called-Name Display) feature supports the display of the name associated with a called number for incoming calls to IP phones configured on a Unified CME. The display name is obtained from the list of Unified CME directory names using directory lookup.
You need to configure the CLI command service dnis dir-lookup under telephony-service configuration mode to use this directory lookup service. For more information on the CLI command service dnis dir-lookup , see Cisco Unified Communications Manager Express Command Reference Guide.
If the display name for a called number is not available in Unified CME directory names, the display name can be added using the CLI command directory entry . For more information on the CLI command directory entry , see Cisco Unified Communications Manager Express Command Reference Guide.
When a phone receives two simultaneous calls, there is a slight time difference between the calls being acknowledged by the phone. Called-name Display is only for the first call acknowledged by the phone. Even when the first call is disconnected and the second call is in ringing state, Called-name Display feature does not work for the second call.
For an example of Called-Name Display , see Example for Called-Name Display for Voice Hunt Group
The called-name display feature for ephone-dns can display either of the following types of name:
Name for a directory number in a local directory
Name associated with an overlay directory number. Calls to the first directory number in a set of overlay numbers will display a caller ID. Calls to the remaining directory numbers in the overlay set will display the name associated with the directory number.
This is an example of Called-Name Display for ephone-dns. If order-entry agents are servicing three catalogs with individual 800 numbers configured in one overlay ephone-dn set, they need to know which catalog is being called to give the correct greeting, such as “Thank you for calling catalog N . May I take your order?”
From Unified CME Release 12.0 onwards, the Dialed Number Identification Service feature is supported for phones configured under voice hunt group on on Cisco 4000 Series Integrated Services Routers. The Dialed Number Identification Service is supported on Peer, Sequential, Parallel, and Longest-Idle voice hunt groups. Support is introduced for SIP Phones on Cisco IP Phones 7800 and 8800 Series as part of the Unified CME 12.0 Release. For information on configuring Called-Name Display feature, see Called-Name Display.
Cisco Unified CME 4.3 increases the number of entries supported in a search results list from 32 to up to 240 when using the directory search feature. For example, if a user enters smith as the last name, all 240 matches are displayed on eight different pages, with 30 entries per page. If multiple pages are required, the phone displays two new softkeys, “Next” and “Prev” that the phone user can press to move back and forth between the previous and next pages. Text such as “Page 2 of 3" displays to indicate the current and total pages on the search results.
