Creating the Default SIP Configuration File
In the default configuration file (SIPDefault.cnf), Cisco recommends 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, you will want to consider if the phones are required to register with a proxy
server, and which codec the phones will use when initiating a call).
By maintaining these parameters in the default configuration file, you can perform global changes, such
as upgrading the image version, without having to modify the phone-specific configuration file for each
phone.
Before You Begin
•

•
The MAC address of a phone is identified on the middle sticker adhered to the base of the phone
and can also be viewed on the Network Configuration menu.
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 contain 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, Cisco recommends that you define the parameters
that you want to apply to all phones in the default configuration file (SIPDefault.cnf).
Ensure that you have downloaded the SIPDefault.cnf file from Cisco.com to the root directory of
your TFTP server.
Review the guidelines and restrictions documented in the
on page 2-4.
For a complete list of the SIP parameters that you can configure, see the
SIP Settings" section on page 3-5.
