Chapter 9 Troubleshooting
Symptoms and Actions
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 (the 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 the Cisco ATA configuration file is synchronized with its configuration file located at the TFTP server. This synchronization update of the cached value occurs at approximate intervals determined by the CFGInterval parameter value as well as when the Cisco ATA powers up or resets.
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 contact the TFTP server for the Cisco ATA configuration file.
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 The 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.
Symptom The Cisco ATA contacts the TFTP server more often than specified in the CfgInterval parameter.
Possible Cause The ToConfig parameter is not set to 0.
Recommended Action After the Cisco ATA has a valid configuration file, the ToConfig parameter must be set to 0. If it is not set to 0, the Cisco ATA will attempt to contact the TFTP server too frequently.
Symptom Cannot place call.
Possible Cause Equipment failure on the network.
Recommended Action Replace defective network equipment.
