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 “Configuring SIP Parameters via a TFTP Server” section on
page 2-6, you can also modify your SIP parameters using the configuration files.
As explained in the “Configuring SIP Parameters” section on page 2-5, there are
two configuration files 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 not required, we recommend 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 an easier task. You can then
define only those parameters that are specific to a phone in the phone-specific
configuration file. Phone-specific parameters should only be defined in a
phone-specific configuration file or 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), we recommend that you
maintain the SIP parameters that are common to all of 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.
