DHCP Generic Setup
This document is limited to describing a generic administration that works with the 9600 Series
SIP IP Telephones. Three DHCP software alternatives are common to Windows operating
systems:
● Windows NT
®

● Windows 2000
®
DHCP Server
● Windows 2003

DHCP Server
Any other DHCP application might work. It is the responsibility of the customer to install and
configure the DHCP server correctly.
DHCP server setup involves:
1. Installing the DHCP server software according to vendor instructions.
2. Configuring the DHCP server with:
● IP Addresses available for the 9600 Series SIP IP Telephones.
● The following DHCP options:
- Option 1 - Subnet mask.
As described in Table 3
, item 3.
- Option 3 - Gateway (router) IP Address(es).
As described in Table 3
, item 1. If using more than one address, the total list can
contain up to 127 total ASCII characters. You must separate IP Addresses with
commas with no intervening spaces.
- Option 6 - DNS server(s) address list.
If using more than one address, the total list can contain up to 255 total ASCII
characters. You must separate IP Addresses with commas with no intervening spaces.
At least one address in Option 6 must be a valid, non zero, dotted decimal address.
- Option 12 - Host Name.
Value is AVohhhhhh, where: o has one of the following values based on the OID (first
three octets) of the telephone’s MAC address: “A” if the OID is 00-04-0D, “B” if the OID
is 00-1B-4F, (SIP software Release 2.0+), “E” if the OID is 00-09-6E, “L” if the OID is
00-60-1D, “T” if the OID is 00-07-3B, (SIP software Release R2.0+) and “X” if the OID
is anything else, and where hhhhhh are ASCII characters for the hexadecimal
representation of the last three octets of the telephone’s MAC address.
- Option 15 - DNS Domain Name.
This string contains the domain name to be used when DNS names in system
parameters are resolved into IP Addresses. This domain name is appended to the
DNS name before the 9600 IP Telephone attempts to resolve the DNS address.
Option 15 is necessary if you want to use a DNS name for the HTTP server.
Otherwise, you can specify a DOMAIN as part of customizing HTTP as indicated in
DNS Addressing
