This chapter explains how to change parameters to customize them for your operating 
environment. In all cases, you are setting a system parameter in the telephone to a desired 
value. 

 lists:

●

the parameter names, 

●

their default values, 

●

the valid ranges for those values, and 

●

a description of each one. 

 is a comprehensive list of all the parameters you can configure. However, you do not 

have to set every parameter. In most cases, you will include only those parameters in the 
settings file that are specific to your own environment and let the deskphones use the default 
values for the remaining ones. 

Note:

At a minimum, be sure to set these important SIP-related parameters: 
SIP_CONTROLLER_LIST, SIPDOMAIN, SNTPSRVR, GMTOFFSET, 
DSTOFFSET, DSTSTART, and DSTSTOP.

For DHCP, the DHCP Option sets certain parameters to the desired values as discussed in 

on page 47. For HTTP, the parameters in 

 are set to desired 

values in the script (46xxsettings) file. For more information on working with the settings files, 
see 

on page 67. 

Avaya recommends that you administer options on the 1603SW-I SIP IP Deskphones using 
script files. This is because some DHCP applications have limits on the amount of 
user-specified information. The administration required can exceed those limits for the more 
full-featured deskphone models. 

Some parameters can be changed using the deskphone dialpad. For example, you might 
choose to completely disable the capability to enter or change option settings from the dialpad 
using local administrative (Craft) procedures. You can set the system value, PROCPSWD, as 
part of standard DHCP/HTTP administration. If PROCPSWD is non-null and consists of 1 to 7 
digits, a user cannot invoke any local options without first pressing Mute and entering the 
PROCPSWD value. For more information on dialpad options, see the Avaya one-X™ 
Deskphone Value Edition SIP for 1603SW-I IP Deskphones Installation and Maintenance 
Guide.
