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.
