For the server, enter the username, SIP server authorization name, and password for the

device, if required. The authorization name and password are the values LifeSize Room

uses for authentication; these values are only required if the registrar or proxy require

authentication.

You can also configure proxy settings to enable and configure the SIP proxy and SIP

registrar. SIP devices use register settings to dynamically register their current location.

Advanced SIP preferences enable you to change the SIP UDP or TCP signaling ports and

the communication path to use for SIP registration.

Configuring NAT/Firewall Settings

You can configure your system to use a static Network Address Translation (NAT) server to

traverse your firewall by setting Administrator Preferences : NAT/Firewall. You can set

the public IP address and identify UDP and TCP port numbers to allow communications with

devices outside of your private network. This configuration also requires changes on your

router to forward the selected ports to the private IP address of the LifeSize device.

Configuring Call Preferences

Users can set preferences for calls such as network bandwidth and auto answer options.

Refer to "User Preferences" on page 21 for details about these preferences. For more

information about Auto Answer options, refer to "Automatically Answering Calls" on

page 12.

Administrators can also configure the maximum call time in Administrator Preferences :

Call.

Managing Bandwidth

By default, calls automatically detect the available bandwidth in the connection and connect

at that rate. If a device with lower bandwidth joins a call, the call slows to the highest

common bandwidth of all devices in the call. If a device with the lowest bandwidth in a call

disconnects from the call, the call increases its speed to the originating common bandwidth.

Administrators can specify the maximum call speed for a call by setting the Administrator

Preferences : Calls : Incoming/Outgoing Maximum Bandwidth preferences. This setting

overrides any bandwidth a user may specify when placing an outgoing call.

The system supports 12 different languages. Users can select a preferred language during

the initial configuration of the system or change it at any time by changing the value in User

Preferences : Appearance.
