The file name must contain the C620 MAC address, which is printed on a label on the back of the device. For example, a Snom C620 SIP Wireless Conference Phone with the MAC address of 00:11:A0:10:6F:2D would download the C620_0011A0106F2D.cfg file.
Page 115: Securing Configuration Files With Aes Encryption
You can encrypt your configuration files to prevent unauthorized users modifying the configuration files. The C620 firmware decrypts files using the AES 256 algorithm. After encrypting a file and placing it on your provisioning server, you can enable the C620 to decrypt the file after fetching it from the server.
Page 116 C620 Administrator and Provisioning Manual To enable configuration file decryption: 1. On the WebUI, click Servicing > Provisioning. 2. On the Provisioning page under Resynchronization, select Use Encryption for configuration file. 3. Enter the 16-character passphrase that you created when you encrypted the configuration file.
