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.
5.3.1
Prerequisites
1. An LDAP server is present and accessible to the phone’s network. The standard Server
port for LDAP is
389
, the standard transport for LDAP is
TCP
.
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 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 OpenScape Desk Phone CP-
for OpenScape Voice.
In Microsoft Active Directory, the standard LDAP attribute
telephoneNumber
is typically
populated as follows:
+1<area code><call number>
. However, in a standard configura-
tion, OpenScape Desk Phone CP will not handle this dial string correctly, due to the
+1
pre-
fix. Therefore, it is recommended to use the
ipPhone
field, which is typically unused in Ac-
tive Directory. It can be found in the
Telephones
tab of the Active Directory User Manager.
