About Authentication
The VCS can be configured to use a username 
and password-based challenge-response 
scheme to permit endpoint registrations. This 
process is known as authentication.
In order to authenticate with the VCS, the 
endpoint must supply it with a username.  
For TANDBERG endpoints using H.323, the 
username is the endpoint’s 
Authentication ID
for TANDBERG endpoints using SIP it is the 
endpoint’s 
Authentication Username
.
For details of how to configure 
endpoints with a username and 
password, please consult the 
endpoint manual. 
In order to verify the identity of the device, 
the VCS needs access to a database on 
which all authentication credential information 
(usernames, passwords, and other relevant 
information) is stored.  This database may 
be located either locally on the VCS, or on 
an LDAP Directory Server.  The VCS looks up 
the endpoint’s username in the database 
and retrieves the authentication credentials 
for that entry.  If the credentials match those 
supplied by the endpoint, the registration is 
allowed to proceed. 
The VCS supports the ITU H.235 specification 
[
] for authenticating the identity of H.323 
network devices with which it communicates.

Configuring Authentication
To configure Authentication options:
VCS Configuration > Authentication > Configuration 
You will be taken to the 
Authentication Configuration
 page (shown below).
Authentication username
The 
Authentication Username
 is the name that the VCS uses when authenticating with other systems.  For example, when forwarding an invite from an 
endpoint to another VCS, that other system may have authentication enabled and will therefore require your local VCS to provide it with a username 
and password. Traversal clients must always successfully authenticate with traversal servers before they can be used.
The authentication username and password for your local VCS must be stored on either the local database or LDAP database (depending on which has 
been enabled), along with all the other authentication usernames and passwords.  When your local VCS receives an authentication request, it looks up 
its own username in the database and sends the corresponding authentication credentials, along with the username, to the system that requested it.  
If the username and authentication credentials match those stored on the requesting system’s database, the communication can continue.
Registration Control
Authentication password
Specifies the password to be used by the 
VCS (in conjunction with the Authentication 
username) when the VCS is authenticating 
with another system.
