Configuring Sip Settings - LifeSize Passport User Manual

Set the Gatekeeper Mode preference to Auto if you wish to have the system automatically
discover a gatekeeper. You can also set the Gatekeeper Mode preference to Manual to
manually choose a gatekeeper. If set to Manual, specify the IP address and port for the
primary gatekeeper.
When you select the Register button in Administrator Preferences : Communications :
H.323, icons appear in the status bar to indicate the status of the registration process with
the H.323 gatekeeper. The yellow H.323 icon
trying to register with the gatekeeper. If the registration fails, the red H.323 icon
appears. If the system is registered to a gatekeeper, the system displays its status.
Configuring a secondary H.323 gatekeeper with the Gatekeeper IP Address 2 and
Gatekeeper Port 2 preferences is optional.
Enabling H.460 Support for H.323 Calls
LifeSize systems support the H.460 protocol for firewall and NAT traversal of H.323 calls.
You must have an H.460 server configured in your environment for this feature to function
properly.
Note: If you configure H.323 settings and enable H.460 support, the system ignores
preferences in Administrator Preferences : Network : NAT.
To enable H.460 client support on a LifeSize system, configure the H.323 preferences in
Administrator Preferences : Communications : H.323 as described in "Skype
Configuration Preferences" on page 43 with the following exceptions:
• Choose Manual for the Gatekeeper Mode preference.
• For the Gatekeeper IP Address 1 and Gatekeeper Port 1 preferences, enter the IP
address and port number of the H.460 server that is configured in your environment.
• Choose Enabled for the H.460 preference.
• Navigate to Register and click OK.
Note: If you enable H.460 and specify the IP address and port number of a secondary
gatekeeper with the Gatekeeper IP Address 2
preferences, the system ignores the secondary gatekeeper.
