Chapter 9 Troubleshooting
For example, for a computer with the IP address 172.28.78.90 and port number 9001
(172.28.78.90.9001), you would enter the following on your telephone handset:
1* 7* 2* 1 1* 2* 8* 1 1* 7* 8* 1 1* 9* 0* 1 1* 9* 0* 0* 1* *
To operate the debug capture program prserv.exe, place the prserv program in a folder on your PC; then
at the DOS prompt of the folder where you have placed it, enter:
C:> prserv port.log
where port is the port number you have selected. If you do not enter port.log, debug information still
appears on your screen, but it is not saved to a log file.
After you finish capturing debug information, you can stop the log program by entering Ctrl-C at the
DOS prompt. The log file created is named port.log. If you restart the process without changing the name
of the log file, any new debug information is appended to the end of the original file.
Contact Cisco TAC for more information. See the
for instructions.
You should also have access to a sniffer or LAN analyzer.
For security reasons, Cisco recommends that you do not use the web interface over the public network.
Caution
Disable the web interface, using the UIPassword parameter, before the Cisco ATA is moved from the
service provider site.

Frequently Asked Questions

Does the Cisco ATA support power denial when disconnecting a call?
Q.
A. No. However, the Cisco ATA can be configured to reverse the voltage polarity when a call is
connected or disconnected. See the
Q. How can I recover the box if I forgot the password?
There are two important passwords. One is the UIPassword, which protects access to the Cisco ATA
A.
Web Server interface; the other is the EncryptKey, which protects access to the TFTP configuration file.
If you forget the value for the UIPassword but still have access to TFTP-stored configuration file, you
can modify the UIPassword via TFTP. However, if you are not configuring the Cisco ATA via TFTP, or
if you forget both passwords, the only way you can recover the box is to have physical access to the box
and do a factory reset on the box via the box voice configuration menu interface (Access Code:
FACTRESET#). See the
