You can also disable SSH and web access on the system by configuring preferences in the
user interface. By default, Telnet access is disabled. For more information, refer to the
LifeSize Video Communications Systems Administrator Guide.
Network Bandwidth
Poor audio and video quality may result from insufficient bandwidth on your network.
LifeSize recommends that your network be capable of at least 1 Mb/s (incoming and
outgoing) for a high definition video call. During video calls with lower bandwidths, LifeSize
systems automatically select the best resolution that can be achieved with the available
bandwidth.
Domain Name Service Server
If you intend to use domain addresses for placing calls you must configure a Domain Name
Service (DNS) server, or use a Dynamic Host Configuration Protocol (DHCP) server that
automatically sets a DNS server.
Initial Configuration
During the installation process, your LifeSize system prompts you to configure it for the first
time. LifeSize recommends that you gather all the necessary information prior to installation.
The following sections provide guidelines for collecting and a means of recording this data.
You may need to consult your network administrator for network settings and system
identification information.
Note: The initial configuration screens also appear when you perform a system reset. For
more information, refer to “Restoring Default Settings” in the LifeSize Video
Communications Systems Administrator Guide.
