Description
contents of DHCP Option 6. At least one address in option 6 must be a valid, nonzero,
dotted decimal address, otherwise the DNS address fails.
Specifies the host name.
AVohhhhhh, where:
• o is one of the following values based on Object Unique Identifier (OUI) derived from
the first three octets of the deskphone MAC address:
- A if OUI is 00-04-0D
- B if OUI is 00-1B-4F
- E if OUI is 00-09-6E
- L if OUI is 00-60-1D
- T if the OUI is 00-07-3B
- X if the OUI is anything else
• hhhhhh are the ASCII characters for the hexadecimal representation of the last
three octets of the deskphone MAC address.
Specifies the domain name. The domain name is required to resolve DNS names into
IP addresses.
Configure this option if you use a DNS name for the HTTP server. Otherwise, you can
specify a domain as part of customizing the HTTP server.
This domain name is appended to the DNS addresses specified in option 6 before the
deskphone attempts to resolve the DNS address. The deskphone queries the DNS
address in the order they are specified in option 6. If there is no response from an
address, the deskphone queries the next DNS address.
As an alternative to administering DNS by DHCP, you can specify the DNS server and
domain name in the HTTP script file. If you use the script file, you must configure the
DNSSRVR and DOMAIN parameters so that you can use the values of these
parameters in the script.
Note:
Administer option 6 and option 15 appropriately with DNS servers and domain
names respectively.
Specifies the SNTP IP address list. List servers in the order of preference. The
minimum length is 4 and the length must be a multiple of 4.
Specifies the encapsulated vendor-specific options that clients and servers use to
exchange the vendor-specific information. Option 43 is processed only if the first code
in the Option is 1 with a value of 6889. All values are interpreted as strings of ASCII
characters that are accepted with or without a null termination character. Any invalid
value is ignored and the corresponding parameter value is not set.

Specifies the DHCP lease time. If this option is not received, the DHCPOFFER is not
accepted. Assign a lease time of six weeks or greater. If this option has a value of
