CfgInterval
Description
Use this parameter to specify the number of seconds between each configuration upda te. The Cisco ATA
will also upgrade its signaling image if it detects that the TFTP server contains an upgraded image.
For example, when using TFTP for configuration, the CiscoATA contacts TFTP each time the interval
expires to get its configuration file.
You can set CfgInterval to a random value to achieve random contact intervals from the Cisco ATA to
the TFTP server.

EncryptKey
Description
This parameter specifies the encryption key that is used to encrypt the CiscoATA configuration file on
the TFTP server.
The cfgfmt tool, which is used to create a CiscoATA binary configuration file (see the “Using the
EncryptKey Parameter and cfgfmt Tool” section on page 3-11), automatically encrypts the binary file,
using the rc4 encryption algorithm, when the EncryptKey parameter has a value other than 0.
