Video and Voice Dialing Preferences
LifeSize systems support either the IP or ISDN protocol for video dialing. The default setting
for the Video Dialing preference is Auto which enables the system to determine the best
method to use to place calls.
LifeSize Express 200 supports VoIP and ISDN for voice calls. VoIP uses H.323 or SIP.
When placing a call using the Voice button on a LifeSize Phone connected to the system,
you can dial IP addresses as well as VoIP or ISDN phone numbers.
When placing a call using the remote control or using the Video button on the phone you
can dial IP addresses. This enables systems inside a corporate network without access to a
gateway to call other LifeSize systems in the network using system IP addresses.
Network Settings
By default, DHCP is enabled on LifeSize systems. If you choose Disabled for the DHCP
preference, you must enter an IP address (the locally configured IP address if not assigned
by a DHCP server), Subnet Mask (used to partition the IP address into a network and host
identifier), and Default Gateway (the IP address of the default gateway the system uses).
IP Address: ___________________________________________________________
Subnet Mask: _________________________________________________________
Default Gateway: ______________________________________________________
You can enter the Hostname of the system. If you do not have a DHCP server that
automatically sets a DNS server, you can enter the IP addresses to configure DNS Servers.
You can also define the domain names to search when resolving hostnames. DNS
translates names of network nodes into addresses; specify this preference to use DNS to
resolve the hostnames of devices to IP addresses.
Hostname: ____________________________________________________________
DNS Servers: __________________________________________________________
Name Search Domains: _________________________________________________
If you choose an option other than Auto (the default) for the Network Speed preference,
ensure that the option matches the speed and duplex configured on your network switch.
Network Speed: ________________________ Network Duplex: _________________
You can enter the hostname or IP address of a Network Time Protocol (NTP) server to set
the system date and time automatically. The LifeSize system ignores the value you specify
for the NTP Server Hostname if the DHCP preference is set to Enabled and the DHCP
server can pass an NTP server address to the LifeSize system.
Network Time Protocol (NTP): ____________________________________________
