Debugging
Symptom The red LED is flashing slowly on the function button.
Possible Cause The Cisco ATA is trying to obtain the DHCP address or the software image is being upgraded.
Possible Cause The Ethernet cable is unplugged.
Recommended Action Plug in the Ethernet cable.
Symptom Voice prompt returns Upgrade not available message. This can only occur if you are using the executable-file upgrade method.
Possible Cause You are attempting to upgrade to the existing version.
Recommended Action You do not need to upgrade.
Symptom Voice prompt returns Upgrade failed message. This can only occur if you are using the executable-file upgrade method.
Possible Cause You have entered an incorrect IP address.
Recommended Action Enter the correct IP address.
Possible Cause Software image is corrupted.
Recommended Action Upgrade software image.
Symptom No dial tone.
Possible Cause No user ID was entered.
Recommended Action Enter the correct user ID.
Symptom Incorrect dial tone.
Possible Cause Check the web interface for your DialTone setting. The default is U.S.
Recommended Action Set the correct country DialTone value.
Debugging
The MS-DOS Windows-based debugging program tool, prserv.exe, is included in every software upgrade package. The tool is also available from Cisco TAC. The prserv program is used in conjunction with the NPrintf configuration parameter. This file serves as an upgrade server that captures debug information sent by the Cisco ATA software to your PC’s IP address and port number. This debug file (prserv.exe) compiles the information from the Cisco ATA into a readable log file. To capture this "NPRINTF" information, you must know the IP address of the PC using the prserv program, illustrated as follows:
