Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide (H.323)
OL-4008-01
Chapter3 Configuring the CiscoATA for H.323
Configuring the Cisco ATA Using a TFTP Server
Procedure
Step 1 Using the voice configuration menu, set the parameter TftpURL to the IP address or URL of the TFTP
server. For more information on setting the TftpURL parameter, see the “TftpURL” section on page 5-5.
For information about using the Cisco ATA voice configuration menu, see the “Voice Configuration
Menu” section on page 3-15.
Note If you are not using a DHCP server to provide the TFTP server location, you must manually
configure the TftfURL. You can do this by using the voice configuration menu without first
obtaining network connectivity for the Cisco ATA. If you want to configure this value using the
Web configuration page, you first must obtain network connectivity by using the voice
configuration menu to statically configure IP address information (see the “Voice Configuration
Menu” section on page 3-15).
Step 2 Use the default value of 1 for the Cisco ATA parameter DHCP.
Step 3 Use the default value of 1 for the Cisco ATA parameter UseTftp.
This completes the parameter settings you need to configure for this procedure. The Cisco ATA will
contact the manually configured TFTP server that contains the Cisco ATA configuration file.
Other DHCP Options You Can Set
The following parameters can also be configured with DHCP:
• Boot file name of DHCP header—The ata<macaddress> binary Cisco ATA configuration file,
which can have a maximum of 31 characters and can be any name with printable ASCII characters
• Client PC address
• DHCP option 1—Client Subnet Mask
• DHCP option 3—Routers on the client’s subnet
• DHCP option 6—One or two Domain Name servers
• DHCP option 42—One or two Network Time Protocol servers
• DHCP option 43—Set this option to identify the protocol (for example, H.323)
• DHCP Option 60 (DHCP_VENDOR_CLASS_ID)—Use this parameter to identify the type of
Cisco ATA box (ATA186 or ATA188).
Without Using a DHCP Server
Use the following procedure if you are not using a DHCP server in your environment but are still using
a TFTP server to obtain the Cisco ATA configuration file:
Procedure
Step 1 Set the DHCP parameter to 0.
Step 2 Set the UseTFTP parameter to 1.
Step 3 Set the Cisco ATA parameter TftpURL to the IP address or URL of the TFTP server. For more
information on setting the TftpURL parameter, see the “TftpURL” section on page 5-5.
