A Network Management

DHCP (Dynamic Host Configuration Protocol) Server
To establish communication over a VoIP network, IP addresses must be assigned to IP-CSs and the PBX 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. Using a DHCP server allows you to centrally
manage and automate the assignment of IP addresses.
IPCMPR/DSP Cards
Note
•
The PBX is not able to act as a DHCP server. To use the DHCP client function of IP-CSs, a separate
DHCP server is required on the network, as shown above.
•
An IP-CS cannot request IP addresses from a DHCP server on another LAN (connected through an
IP network). They can only receive IP addresses from a DHCP server on the same LAN. Therefore,
when IP-CSs are located on several LANs, a DHCP server is required on each LAN. If a DHCP server
is not present on the LAN, IP addresses for IP-CSs on that LAN must be assigned manually.
