Modifying SIP Parameters via a TFTP Server

If you have set up your phones to retrieve their SIP parameters via a TFTP server as described in the
"Modifying SIP Parameters via a TFTP Server" section on page
parameters using the configuration files.
As explained in the
that you can use to define the SIP parameters; the default configuration file and the phone-specific
configuration file. If used, the default configuration file must be stored in the root directory of your TFTP
server. The phone-specific configuration file can be stored in the root directory of the TFTP server or a
subdirectory in which phone-specific configuration files are stored.
While it is not required, Cisco recommends that you use the default configuration file to define values
for SIP parameters that are common to all phones. Doing so will make controlling and maintaining your
network easier. You can then define only those parameters that are specific to a phone in the
phone-specific configuration file. Phone-specific parameters should be defined only in a phone-specific
configuration file or should be manually configured. Phone-specific parameters should not be defined in
the default configuration file.

Modifying the Default SIP Configuration File

In the default configuration file (SIPDefault.cnf), Cisco recommends that you maintain the SIP
parameters that are common to all your phones.
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.
