Local Settings
Asterisk Service
Enable Asterisk service for Fail2Ban. The default setting is disabled. Please make
sure both "Enable Fail2Ban" and "Asterisk Service" are turned on in order to use
Fail2Ban for SIP authentication on the UCM6200.

LDAPSERVER
The UCM6200 has an embedded LDAP server for users to manage corporate phonebook in a centralized
manner.
By default, the LDAP server has generated the first phonebook with PBX DN
"ou=pbx,dc=pbx,dc=com" based on the UCM6200 user extensions already.
Users could add new phonebook with a different Phonebook DN for other external contacts. For
example, "ou=people,dc=pbx,dc=com".
All the phonebooks in the UCM6200 LDAP server have the same Base DN "dc=pbx,dc=com".
Term Explanation:
cn= Common Name
ou= Organization Unit
dc= Domain Component
These are all parts of the LDAP data Interchange Format, according to RFC 2849, which is how the LDAP
tree is filtered.
If users have the Grandstream phone provisioned by the UCM6200, the LDAP directory will be set up on
the phone and can be used right away for users to access all phonebooks.
Additionally, users could manually configure the LDAP client settings to manipulate the built-in LDAP
server on the UCM6200. If the UCM6200 has multiple LDAP phonebooks created, in the LDAP client
configuration, users could use "dc=pbx,dc=com" as Base DN to have access to all phonebooks on the
