• Configuration File Example
Corporate Directory LDAP Attributes
The entry attributes in the corporate directory are mapped through sip.cfg
configuration file attributes to the LDAP attributes first_name, last_name,
phone_number, and others so the SIP application knows how to use them for
searching, dialing, or saving to the local contact directory. Multiple attributes
of the same type are allowed.
The configuration order dictates how the attributes are displayed and sorted.
The first attribute is the primary sort index and the second attribute is the
secondary sort index. The other attributes are not used in sorting.
To limit the amount of data displayed in the corporate directory, filtering of
the entries can be configured for all attribute types. Filtering can be configured
to be retained if the phone reboots.
For more information on LDAP attributes, refer to RFC 4510 - Lightweight
Directory Access Protocol (LDAP): Technical Specification Road Map.
Browsing the Corporate Directory
The SoundPoint IP or SoundStation IP phone will establish a session with the
corporate directory and download enough entries to fill its cache:
• when the corporate directory is first accessed
• when the phone boots up if the background synchronization parameter is
enabled
The requested entries are based on the configured attributes (see previous
section).
If the background synchronization parameter is enabled, a timer is initiated to
permit a periodic download from the corporate directory.
Entries are sorted according to the order in which the first two attributes are
configured (for example, last name, then first name).
The browse position within the corporate directory as well as the attribute
filters are maintained for subsequent corporate directory access can be saved
(if so configured).
Note The maximum of eight attributes can be configured in sip.cfg .
