Dhcp Server - Avaya 3616 Installation Manual

1.4 DHCP Server

Use of a DHCP server is optional. The 3600 Series phones use DHCP by default, however they can also
be individually configured with a fixed IP address information. The IP Office control unit can be used as
a DHCP server, however this is only recommended for 5 or less H.323 IP phones. In other scenarios a
separate DHCP server must be used.
The method and process for configuration will depend on the DHCP server software being used. Refer to
the manufacturers information for details.
1. Information Required
You will need the following information from the customer's network manager:
• The IP address range and subnet mask the phones should use.

• The DNS domain name, DNS server address and the WINS server address.
•
The DHCP lease time.
