Configuring Dialing Options - LifeSize Room User Manual

Configuring Dialing Options

LifeSize Room provides simultaneous video, VoIP, or PSTN connectivity.
You can choose voice and video dialing options during the initial configuration or at any
other time by accessing the Administrator Preferences : Communications. Select the
protocol to use when dialing voice or video calls.
For voice calls, VoIP uses H.323 or SIP, Touch Tone and Pulse use PSTN.
For video calls, choose IP or IP + ISDN or ISDN for ISDN connectivity.
When placing a call off hook (using the Voice button on the phone) 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 dialing on hook (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 Phones in the network
using system IP addresses.
Configuring Network Usage
General network configuration is available from the administrator preferences.
Configuring LAN Properties
To configure network settings, select the Administrator Preferences and Network buttons.
From this menu you can establish DHCP or Static IP network settings.
Note: If you change IP settings the system automatically restarts.
Dynamic Host Configuration Protocol (DHCP) is used to dynamically allocate and assign IP
addresses. DHCP allows you to move network devices from one subnet to another without
administrative attention. You can choose to enable DHCP if a DHCP server is present. If you
disable DHCP, you must identify 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 gateway (IP address of the default gateway the system uses).
You can also define the broadcast IP address of your network, hostname of the system, and
identify the IP addresses to configure DNS servers.
As well, you can define the domain names to search when resolving hostnames. Domain
Name System (DNS) is used for translating names of network nodes into addresses; specify
this preference to use DNS to resolve the hostnames of devices to IP addresses.
