DNS

Domain Name System (DNS), an industry-standard protocol, locates computers on an

IP-based network. IP networks rely on number-based addresses to move information on

the network. However, it is easier to remember user-friendly names than number-based

addresses, so it is necessary to translate user-friendly names into addresses that the

network can recognize. The handset can use DNS for HTTP server IP addresses, SNMP

server IP addresses and the Avaya Aura® Session Manager IP address.

SSON Option

The SSON option follows these rules:



SSON uses DHCP option 242 by default. If a different option setting is used, you

must define the setting in the Admin menu. The allowed range is 128 through 254.



The SSON option number is configurable in the Admin menu.



The SSON option number is configurable in the HAT tool.



Multiple SSON values may be set in the DHCP option string. Each parameter shall

use the syntax "<name>=<value>". You must delimit the parameters by commas

and no blank spaces outside the quoted strings are invalid.



If a parameter is present in both DHCP SSON and the 46xxsettings file, the value

defined in 46xxsettings file shall supersede the value previously found in DHCP

SSON.



Valid parameters for the DHCP SSON option string include any parameter in the

46xxsettings.txt remote configuration file with the exception of the SIP_FAVORITES

parameter that is not valid in SSON.



The DHCP SSON option string is limited in length to 255 characters. It cannot

support all possible parameters at once.
