The Multilingual Name Display Using External LDAP functionality (extension of the Multilingual Name Display feature) uses an external LDAP server to display names for external numbers, speed calls, groups, and other numbers that do not exist in the User and Services Configuration form. That is, when a user dials or receives a number that is not stored in the User and Services Configuration form, the MiVoice Business system queries the number in the external LDAP server. If the number is stored as a contact in the external LDAP server, the external LDAP server returns a name to the MiVoice Business system that is displayed on the 69xx series IP phone.
The MiVoice Business system supports the following external LDAP server directories:
OpenLDAP
Active Directory
Mitel Meta Directory
When you configure a valid external LDAP server, the MiVoice Business system uses the following precedence for the name display based on the search results:
External LDAP server
Telephone Directory form
If a name is not returned from these sources, then the MiVoice Business system displays the name it receives from the Public Switched Telephone Network (PSTN).
The MiVoice Business system connects to an external LDAP server when the external LDAP server is configured or during the start-up of the MiVoice Business system. Once connected, the MiVoice Business system maintains the connection by querying the external LDAP server every 10 minutes. If the connection is lost, the MiVoice Business system requests for the connection during the next search or idle timeout.
You can provide the search criteria for name lookup in the external LDAP server through the following fields of the LDAP Client Configuration form:
Number Search Filter
Number Search Length
LDAP Base DN
Search Scope
If the Number Search Filter is telephoneNumber=%, then the system replaces % with the number and searches the external LDAP server for the number. Based on the number search length specified in the Number Search Length field, the system inserts * (reserved LDAP character for wildcard) to truncate the number to the specified length. For example, if the number search length is 10, then a search for:
96135922122 returns telephoneNumber=*6135922122
6135922122 returns telephoneNumber=*6135922122
5922122 returns telephoneNumber=5922122
14161234567 returns telephoneNumber=*4161234567
NOTE: If the Number Search Filter field includes *, then the system truncates and replaces % with the truncated number without adding an extra *.
MiVoice Business Display Timeout - It is the duration for which the MiVoice Business system delays the name display to the sets for potential name display from the external LDAP server. The default value of this timeout is 50 milliseconds (ms). If no updates are received from the external LDAP server within the timeout period, the existing name received from the Telephone Directory form or the PSTN is displayed. If the updates are received after this timeout, the system caches the updates.
Idle Timeout - It is the idle time duration of the Multilingual Name Display Using External LDAP functionality after which the MiVoice Business LDAP client performs a basic search to check the connection status of the external LDAP server. The default value of this timeout is 10 minutes. If the connection to the external LDAP server is disconnected, the connection is re-established after the next timeout period or during the next name display.
NOTE: If the idle timeout of the external LDAP server is configurable, then Mitel recommends an idle timeout duration greater than 10 minutes.
The values specified in the following fields of the LDAP Client Configuration form determine the fields in the external LDAP server that the MiVoice Business LDAP client uses to look up the first and the last names for the name display:
First Name
Last Name
Common Name Attribute (used if the first and the last names are not specified, or when no results are returned)
All search results are cached in the MiVoice Business system.
The system stores a cache of 3000 entries, with an expiry time of seven days. As new entries are added to the cache, the system scans and deletes expired entries. If the cache is full and there are no expired entries, the system deletes the least used entries.
The cache is not shared through SDS and is not retained over a system reboot.
For more information on when the system cache is cleared, see External LDAP server for Multilingual Name Display in the LDAP Client Configuration form.
The LDAP Client Configuration Profile ID #2 field in the System Options form must specify an external LDAP Server.
The Client Status field in the LDAP Client Configuration form must be set to Enabled.
Supports only an IP address for the LDAP server( FQDN is not supported). Ensure an IP address is configured in the FQDN or IP Address field in the Network Elements form.
Alpha Tagging must be enabled to display consistent results.
The Multilingual Name Display feature must be enabled to use the Multilingual Name Display Using External LDAP functionality. Disabling the Multilingual Name Display feature disables the Multilingual Name Display Using External LDAP functionality.
The Multilingual Name Display Using External LDAP functionality is disabled when the connection to the external LDAP server is lost. For more information, see External LDAP server for Multilingual Name Display in the LDAP Client Configuration form.
If a number is marked as private by the PSTN, then there is no call display. Additionally, if an internal number from the Telephone Directory is marked as private, then only the name is displayed.
Sets display full names if space is available.
SIP devices query their names upon registration.
