LifeSize Room Installation Guide 7
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.
You can select either VoIP, ISDN, Touch Tone or Pulse for the Voice Dialing preference. For
voice calls, VoIP uses H.323 or SIP, Touch Tone and Pulse use PSTN. The default is VoIP.
When placing a call using the Voice button on a LifeSize Phone connected to the system
and voice dialing is set to touch tone or pulse, you can only dial phone numbers using PSTN
connectivity. When voice dialing is set to VoIP, you can dial IP addresses as well as phone
numbers.
When placing a call using the remote control or using the Video button on the phone you
can dial either phone numbers or 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: _________________
