Gatekeeper Discovery 
 

The system will automatically try to register to any available gatekeeper. If a 
gatekeeper responds to the request sent from the codec within 30 seconds this 
specific gatekeeper will be used. This requires auto discovery on the gatekeeper 
as well. If no gatekeeper responds, the system will not use a gatekeeper for 
making H.323 calls and hence an IP-address must be specified manually. 
 

The system will use a specific gatekeeper identified by Gatekeeper IP-address. 
 

 
Gatekeeper IP Address 
 
This is the gatekeeper IP-address that is used if you specify H.323 Call Setup: Gatekeeper and 
Gatekeeper Discovery: Manual. 
 

 
Note that if your system is part of a TANDBERG Expressway™ firewall traversal solution and 
is placed outside the firewall, you should register the IP address of your Border Controller as 
the Gatekeeper IP address and set H.323 Call Setup to Gatekeeper. 
 

 
Authentication Mode 
 

If Authentication Mode is set to Auto and the gatekeeper indicates that it requires 
authentication, the endpoint will automatically try to authenticate itself to the 
Gatekeeper. 
 

If Authentication Mode is set to Off the system will not try to authenticate itself to a 
Gatekeeper, but will still try a normal registration. 
 

 
Authentication ID / Authentication Password 
 
The system sends the Authentication ID and Password to a Gatekeeper for authentication. The 
authentication is a one way authentication from the endpoint system to a Gatekeeper, i.e. the 
endpoint is authenticated to the Gatekeeper. If the Gatekeeper indicates that no authentication is 
required, the endpoint will still try to register. 
 
Multiple H323 Aliases 
 

If set to On, the system will register multiple H.323-IDs on the Gatekeeper based on 
the values of the parameters: System Name, International Name and H.323 ID. 
Up to 3 aliases are possible. 
 

If all fields are empty, the System Name is set to TANDBERG-<serial no> and
