Configuration changes can performed centrally at the boot server:

Configuration files (excluding the master configuration file), contact 

directories, and configuration override files can all be encrypted.

For more information on encrypting configuration files including determining 

whether an encrypted file is the same as an unencrypted file and using the

The SoundPoint IP 300 and 500 phones will always fail at decrypting files. These 
phones will recognize that a file is encrypted, but cannot decrypt it and will display 
an error. Encrypted configuration files can only be decrypted on the SoundPoint IP 
301, 320, 330, 430, 501,550, 600, 601, and 650 and the SoundStation IP 4000 
phones.

The master configuration file cannot be encrypted on the boot server. This file is 
downloaded by the bootROM that does not recognize encrypted files. For more 
information, refer to 

 on page

Configuration File: 
sip.cfg

Specify the phone-specific contact directory and the 
phone-specific configuration override file.
