6.1 Information about Using an IP Network
This section explains common IP network information necessary for setting up networks.
6.1.1 Using a VoIP Network with the Control Box
This Control Box supports SIP (Session Initiation Protocol) devices (Lobby Station, Door Station, and Room
Monitor) and SIP phones for communication on a Voice over Internet Protocol (VoIP) network.
Network Parameters
You will need to have the following IP addressing and QoS information to establish VoIP communication on
your network. This information is typically supplied by a network administrator.
Consult your network administrator for specific values.
Parameter Description
IP telephone IP Address
Identifies the location of IP telephones on the network. Each IP
telephone must have a unique IP address.
Subnet Mask Address
Defines which digits of an IP address are used for the network
address and the host address at each network location. The IP
addresses of the IP telephones and the Control Box must fall within
the same subnet as that of the default gateway (e.g., router) of the
LAN.
Default Gateway Address
Identifies the IP address of the primary gateway (typically a router
or similar device) that exchanges IP packets with the other
gateways on the VoIP network.
IP Address
Identifies the location of the Control Box in the network during VoIP
communications.
VLAN ID
Identifies the ID of the logical segment within the corporate LAN,
through which voice packets from IP telephones travel. For details,
refer to "6.1.3 VLAN (Virtual LAN)".
6.1.2 DHCP (Dynamic Host Configuration Protocol) Server
To establish communication over a VoIP network, IP addresses must be assigned to IP telephones and the
Control Box to identify their locations on the network. While these addresses can be assigned manually, it is
also possible to use a DHCP server to automatically assign IP address information. The Control Box has a
DHCP Server feature. Therefore, the Control Box can act as a DHCP server or DHCP client depending on
its settings. When the Control Box’s DHCP Server feature is enabled, it allows you to centrally manage and
automate the assignment of IP addresses with Web Maintenance Console. For details, refer to "16.2.1
Network Service—[2-1] Server Feature—DHCP(LAN)" in the PC Programming Manual.
