LDAP Interface
200 Application Interfaces
●
Each individual LDAP-queried record is reserved for a definable time in a
Forum 523/524 communications system cache (setting:
Delete cache in
minutes, 50 cache entries per company each with a separate time counter
per entry). You should shorten this time (e. g. to 10 minutes) if, for
example, the assignment of guests and room telephones in a hotel is
managed via the LDAP server. If you set the
Delete cache setting to
0 minutes the cache is not automatically deleted. Delete the cache as
needed. Select the desired company entries on the
Telephony : Extended :
Companies page and click on the LDAP Delete cache button.
● Ideally, call numbers on the LDAP server are saved in the E.123 format
beginning with a plus sign and country code. Furthermore, the bundles
configured in the standard route of a company should have the setting
E.164 conversion (see E.164 conversion starting on page 145). Special call
numbers such as the emergency call number “110” should not be
managed via LDAP, rather in the telephone book of the communications
system.

A call number queried via LDAP is adjusted before use. First of all, the
characters in brackets beginning with “0” are deleted such as, e.g.
“+49(030)1234”. Then all characters are deleted that are not numbers or
plus signs.
If the resulting call number is in the E.123 format, the initial plus sign is
replaced with “00”. In addition, the seizure code of the company standard
route is prefixed and (if configured, see
E.164 conversion starting on
page 145) the own prefix and the own base call number is deleted as
necessary.
If the resulting call number is not in the E.123 format the Phone No. option
on the Telephony : Extended : Companies page determines how it is proc-
essed further:
– Option Phone No. is set to transparent : The call number queried from
the LDAP server is used without any further change.
– Option Phone No. is set to convert : Select this option if the LDAP server
provides call numbers without seizure codes. In addition, call numbers
beginning with “0” have the seizure code of the company standard route
prefixed and (if configured, see
E.164 conversion starting on page 145) the
own prefix and the own base call number is deleted as necessary.
– Option Phone No. is set to convert with trunc code : Select this option if
the LDAP server provides call numbers with seizure codes for the company
standard route. In addition, for call numbers beginning with the seizure
