1.1 Setup1.1.1 Factory DefaultsMany of the settings for this unit have been configured before the unit ships.Where possible, these settings are configured with the optimum or most common values for the setting. Forexample, the port number of the SIP (Session Initiation Protocol) server is set to "5060".However, many of the settings, such as the address of the SIP server or the phone number, have not beenpre-configured, and they must be modified depending on the usage environment. If the port number of the SIPserver is not "5060", the value of this setting must be changed.This unit thus will not function properly using only the factory default settings. The settings for each featuremust be configured according to the environment in which the unit is used.1.1.2 Basic Network SetupThis section describes the basic network settings that you must configure before you can use the unit on yournetwork.You must configure the following network settings:• TCP/IP settings (DHCP [Dynamic Host Configuration Protocol] or static IP address assignment)• DNS server settingsThe unit supports both IPv4 and IPv6.TCP/IP Settings (DHCP or Static IP Address Assignment)A unique IP address must be assigned to the unit so that it can communicate on the network. How you assignan IP address depends on your network environment. This unit supports the following 2 methods for assigningan IP address:Obtaining an IP Address Automatically from a DHCP ServerYou can configure the unit to automatically obtain its IP address when it starts up from a DHCP server runningon your network. With this method, the system can efficiently manage a limited number of IP addresses. Notethat the IP address assigned to the unit may vary every time the unit is started up.For details about the DHCP server, consult your network administrator.Using a Static IP Address Specified by Your Network AdministratorIf IP addresses for network devices are specified individually by your network administrator, you will need tomanually configure settings such as the IP address, subnet mask, default gateway, and DNS servers.For details about the required network settings, consult your network administrator.DNS Server SettingsYou can configure the unit to use 2 DNS servers: a primary DNS server and a secondary DNS server. If youset both DNS servers, the primary DNS server receives priority over the secondary DNS server. If the primaryDNS server returns no reply, the secondary DNS server will be used.For details about configuring the DNS server settings using the unit, or using the Web user interface, seeConfiguring the Network Settings of the Unit in this section.22 Administrator Guide Document Version 2014-041.1.2 Basic Network Setup
