Cisco Systems ATA 186 Procedure if DHCP Server is Under Control of Cisco ATA Administrator, 3-16

Chapter 3 Configuring the Cisco ATA for SCCP

Configuring the Cisco ATA Using a TFTP Server

Note If no DHCP server is found and the Cisco ATA is programmed to find one, the function button continues to blink.

Procedure if DHCP Server is Under Control of Cisco ATA Administrator

Procedure

Step 1 On the DHCP server, set one of the following two options:

•DHCP option 150 (TFTP server IP address)

•Standard DHCP option 66 (TFTP server name)

If you use DHCP option 150, the Cisco ATA will ignore DHCP option 66. However, if you use DHCP option 66, you must turn off DHCP option 150 or set its value to 0.

Note You can turn off the DHCP option 150 request by using the Cisco ATA OpFlags parameter (see the “OpFlags” section on page 5-17).

Step 2 Make sure to use default values for the following Cisco ATA parameters:

•TFTPUrl=0

•UseTFTP=1

•DHCP=1

•CA0orCM0=0

This completes the parameter settings and DHCP options you need to configure for this procedure. The Cisco ATA will contact the DHCP server for the IP address of the TFTP server that contains the Cisco ATA configuration file.

Procedure if DHCP Server is not Under Control of Cisco ATA Administrator

This is the procedure to use if the DHCP server is not under the control of the Cisco ATA administrator, which means that the URL of the TFTP server must be manually configured.

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 5-4. For information about using the Cisco ATA voice configuration menu, see the “Voice Configuration Menu” section on page 3-18.

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 3-18).
