Chapter 2 Getting Started with Your Cisco SIP IP Phone
Installing the Cisco SIP IP Phone
•
The default configuration file must be stored in the root directory of the TFTP 
server. The phone-specific configuration file can be stored in the root 
directory or in a subdirectory in which all phone-specific configuration files 
are located.
•
Each line in the configuration files must use the following format:
variable-name : value ; optional comments
•
Use colons to separate variable names and values. 
•
Only one value can be associated with a variable.
•
The variable and value can have as much white space before or after them and 
can contain any characters. However, if white spaces are needed within the 
value, the value must be enclosed in single or double quotes. If the value is 
enclosed in quotes, the end quote must be the same as the start quote. 
•
After the value, you can include optional comments. Use the semicolon (;) 
and pound (#) delimiters to distinguish the comments.
•
Blank lines are allowed.
•
Comment lines are allowed.
•
Variable names are not case sensitive.
•
Only one variable can be set per line.
•
Distinguish the end of a line using <lf> or <cr><lf>.
•
The variable and value must be on the same line and cannot break the line.
•
Except for parameters used to defined the lines and users on a phone, all other 
SIP parameters can be defined in either the default configuration file or the 
phone-specific configuration file. However, for network control and 
maintenance purposes, we recommend that you define the parameters that 
you want to apply to all phones in the default configuration file 
(SIPDefault.cnf). 
Creating the Default SIP Configuration File
In the default configuration file (SIPDefault.cnf), we recommend that you define 
the SIP parameters that will be common to all of your phones such as the 
image_version parameter and call environment parameters (for example, will the 
phones be required to register with a proxy server and which codec will the 
phones use when initiating a call).
