Example Provisioning Direction from the Server
The following figure shows an example NOTIFY message from the server, directing the units to perform
provisioning. The text "check-sync" is specified for "CFG_RESYNC_FROM_SIP".

2.4.3.6 Encryption

Transferring Encrypted Configuration Files

Unencrypted
configuration
file
To use this method, an encryption key is required to encrypt and decrypt the configuration files. A preset
encryption key unique to each unit, an encryption key set by your phone system dealer, etc., is used for the
encryption. When the unit downloads an encrypted configuration file, it will decrypt the file using the same
encryption key, and then configure the settings automatically.
To decrypt configuration files, the unit uses the encryption key registered to it beforehand. The unit determines
the encryption status by checking the extension of the downloaded configuration file.
Extension of Configuration
File
".e1c"
".e2c"
".e3c"
Other than ".e1c", ".e2c", and
".e3c"

2.4.4 XML Provisioning

XML provisioning is a provisioning method that uses XML formatted configuration files. XML provisioning
consists of a configuration file (.xml) and a schema file (.xsd). The benefits of XML formatted configuration files
are as follows:
•
You can use an XML editor to edit configuration files, which prevents typos in the configuration parameters.
•
XML formatted configuration files integrate better with server applications than plain text configuration files.
