Step 1 Set the UIPassword parameter to a numeric password by using the web server
interface or TFTP profiling.
Step 2 You will be prompted for a password when you try to access the web server or a
configurable IVR parameter.
• In web server mode, enter the password in the UIPassword field of the
password challenge page.
• In IVR mode, enter the password, followed by the # key, at the p-a-s-s-w-d
prompt.
Encrypt Key
Encrypt Key encrypts binary files being transferred over TFTP. You can change
this key for each Cisco ATA 186, so that only one particular box can decode the
information. You can change the encrypt key, using the IVR or web interface.
See the “cfgfmt.exe and ptag.dat Files” section for more information.
The Cisco ATA 186 polls the server at intervals set in CfgInterval to see if it
needs to be upgraded. You can customize this service. For example, you can route
all calls from a particular Cisco ATA 186, based on the Gatekeeper ID, to an
operator.
About Using the DHCP Server
DHCP option 60, DHCP_VENDOR_CLASS_ID, is set to the value ATA186 so
that the DHCP server can identify a Cisco ATA 186.
Parameters that you can set using DHCP are:
• Client IP address
• Client Subnet mask—DHCP option 1
• Routers on the client's subnet—DHCP option 3
• Domain name servers—DHCP option 6
(The Cisco ATA 186 takes up to two DNS servers)
