Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide for SCCP (version 3.0)
OL-4652-01
Chapter 8 Troubleshooting
Symptoms and Actions
• If there is no dial tone, make sure that the telephone line cord from the telephone is plugged into the
appropriate port on the Cisco
ATA. Make sure that your Cisco ATA is properly registered on your
Call Control system. Test another phone; if this phone does not work either, there may be a problem
with the current configuration or with the Cisco
ATA.
• A busy tone indicates that the party you called is not available. Try your call again later. A fast-busy
tone indicates that you dialed an invalid number.
• After power up, if the function button continues to blink slowly, the Cisco ATA cannot locate the
DHCP server. Check the Ethernet connection and the availability of the DHCP server.
• The DHCP server should show an incoming request from the MAC address listed on the product
label or given by the voice prompt.
Symptoms and Actions
Symptom Parameters with values set by using the web server interface or voice configuration menu
revert to their original settings.
Possible Cause You are using TFTP for configuration (UseTftp parameter is set to 1). The Cisco ATA
has a cached version of its configuration file stored in its flash memory; this is what displayed or
played through the web server interface or voice configuration menu. If UseTftp is set to 1, then the
cached value of its configuration file is synchronized with its configuration file located at the TFTP
server.
Recommended Action If you are using TFTP for configuration, do not use the web server interface or
voice configuration menu to modify the value of the Cisco
ATA configuration file. Use the web
server interface or voice configuration menu only to initially configure the Cisco
ATA to use TFTP
for configuration.
Symptom Unable to access the web configuration page.
Possible Cause Software versions earlier than 2.0 require the web configuration page to be enabled
using option 80# on the voice configuration menu.
Recommended Action Upgrade the software.
Symptom The Cisco ATA does not seem to be configured using the TFTP server.
Possible Cause TFTP server address is not properly set.
Recommended Action Ensure that the TftpURL is correctly set to the URL or IP address of the TFTP
server that is hosting the configuration file for the Cisco
ATA. If you are using DHCP to supply the
TFTP server IP address, make sure that the TftpURL is set to 0. Also, unless the TftpURL is an IP
address, be sure that the DNS1IP and DNS2IP values are properly set to resolve the TftpURL
supplied by DHCP.
