Using Atapname.exe Tool To Obtain Mac Address; Using Encryption With The Cfgfmt Tool - Cisco ATA186-I1 Administrator's Manual

Chapter 3 Configuring the Cisco ATA for SCCP

Using atapname.exe Tool to Obtain MAC Address

This bundled tool is useful for converting the dotted decimal version of the Cisco ATA MAC address
(available on the Cisco ATA Web configuration page or from the voice configuration menu code 24#)
to its default Cisco ATA profile name. This name has the following format:
ataxxxxxxxxxxxx
where each xx is the two-digit, lower-case hexadecimal representation of each integer in the dotted,
decimal version of the Cisco ATA MAC address. This is the name you use for the unique Cisco ATA
binary configuration file.
The following command and output show an example of this command.
Command Example
atapname.exe 10.20.30.40.50.60
Command Output
ata0a141e28323c
The same functionality is available from the voice configuration menu (voice menu code 84#), which
Note
will announce the Cisco ATA profile name.

Using Encryption With the cfgfmt Tool

The EncryptKey or EncryptKeyEx parameter can be used to encrypt binary files that are transferred over
TFTP. You can change encryption keys for each Cisco ATA so that only one specific Cisco ATA can
decode the information.
Cisco strongly recommends using the EncryptKeyEx parameter for encryption because this parameter
provides a stronger encryption than the EncryptKey parameter that was used in Cisco ATA software
releases prior to release 2.16.
You must use version 2.3 of the cfgfmt configuration-file generation tool to use the new EncryptKeyEx
parameter. This tools comes bundled with Cisco ATA software version 3.0. To verify that you have
version 2.3 of the cfgfmt tool type the following command:
cfgfmt
The version number of the cfgfmt tool will be returned.
You can configure the EncryptKeyEx parameter by using the Cisco ATA Web configuration page or by
using the TFTP configuration method. (For more information, see the
page
You can configure the EncryptKey parameter by using the Cisco ATA Web configuration page, the
voice configuration menu, or by using the TFTP configuration method. (For more information, see the
"EncryptKey" section on page
By default, the Cisco ATA-specific ata<macaddress> configuration file(s) are not encrypted. If
encryption is required, however, you must manually configure the EncryptKeyEx or EncryptKey
parameter before you boot up the Cisco ATA so that the TFTP method is secure. The Cisco ATA uses
the RC4 cipher algorithm for encryption.
