How to Set Up the Corporate Phonebook (LDAP)
4.2 How to Set Up the Corporate Phonebook (LDAP)
The Corporate Phonebook function is based on an LDAP client that can be connected to the
company’s LDAP service. A variety of LDAP servers can be used, for instance Microsoft Active
Directory, OpenLDAP, or Apache Directory Server.
4.2.1 Prerequisites
1. An LDAP server is present and accessible to the phone’s network. The standard port for
LDAP is 389.
2. Query access to the LDAP server must be provided. Unless anonymous access is used, a
user name and password must be provided. It might be feasible to use a single login/pass-
word for all OpenScape Desk Phone CP Desk Phones.
3. To enable dialing internal numbers from the corporate phonebook, an LDAP entry must be
provided that contains the proper number format required by the HiPath system.
In Microsoft Active Directory, the standard LDAP attribute telephone Number is typically
populated as follows: +1<area code><call number>. However, in a standard configuration,
OpenScape Voice will not handle this dial string correctly, due to the +1 prefix. Therefore,
it is recommended to use the ipPhone field, which is typically unused in Active Directory. It
can be found in the Telephones tab of the Active Directory User Manager.

LDAP is available only on phones.
