Q.931 port
If in a cluster, the non-live and live Q.931
ports used for H.323 call setup can be
changed.
Leave as the default, or select ports that
are not being used by the Content
Server (see
Port information).
RAS port
If in a cluster, the non-live and live RAS
ports used for gatekeeper registration can
be changed.
Leave as the default, or select ports that
are not being used by the Content
Server (see
Port information).
Authentication
By default, authentication is Off.
If the gatekeeper requires systems to
authenticate with it before they are
allowed to register, select Auto and
supply the User name and Password
to be used by the Content Server.
User name
The user name to authenticate to the
gatekeeper.
Password/Pas
sword confirm
The password to authenticate to the

Advanced
H.323 settings
Use static
ports
Deselected by default. This means that the
ports to use are allocated dynamically
when opening a TCP/UDP connection.
Static ports can be enabled by selecting
the check box and specifying the
required Port range. This may be
necessary if the Content Server is to
make calls through a firewall.
Port range
3230 to 3270 is the standard firewall port
range: select the range appropriate to your
local firewall settings.
NAT
Network Address Translation (NAT) is
used when the Content Server is
connected to a router with NAT support.
The default setting is Off.
If On, the Content Server uses the
specified NAT address in place of its
own IP address within Q.931 and
H.245.
If set to Auto, the Content Server tries to
determine whether the NAT address or
the real IP address should be used.
This makes it possible to call endpoints
on both sides of the NAT router.
If you select either On or Auto, enter the
NAT address.
NAT address
The global, external address to a router
with NAT support.
In the router, the following ports must be
routed to the system’s IP address:
• Port 1720 for a standalone
Content Server. If the Content
Server is in a cluster, the ports
specified as the non-live and live
Q.931 ports in the Gatekeeper
settings section above.
• The port range specified in Port
Range, above for example 3230
to 3270. Contact your Cisco
