Parameters for Configuration Method and Encryption
TftpURL
Description
Use this parameter to specify the IP address or URL of the TFTP server. This string is needed if the DHCP
server does not provide the TFTP server IP address. When the TftpURL parameter is set to a non-zero value,
this parameter has priority over the TFTP server IP address supplied by the DHCP server.
Optionally, you can include the path prefix on the TFTP server from which the Cisco ATA will download
its configuration file.
For example, if the TFTP server IP address is 192.168.2.170 or www.cisco.com, and the path prefix for
the configuration file on the TFTP server is in /ata186, you can specify the URL as 192.168.2.170/ata186
or www.cisco.com/ata186.
Note From the voice configuration menu, you can only enter the IP address; from the Web configuration page,
you can enter the actual URL.

CfgInterval
Description
Use this parameter to specify the number of seconds between each configuration update. The Cisco ATA
will also upgrade its signaling image it it detects that the TFTP server contains an upgraded image.
When using TFTP for configuration, the Cisco ATA 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.
