Logging Information for Troubleshooting
To collect troubleshooting information in a log file, follow these steps:
Procedure
Step 1
Press the Menu key on the phone.
Step 2
Select Settings > Network Configuration.
Step 3
If the menu is locked, press **# to unlock it.
Step 4
Press **3 to access the Device Logs screen.
Step 5
Enter the host server and port to which debug information should be sent.
For example, if you want degug information sent to port 9001 on a server whose
IP address is 192.168.2.170, press 192*168*2*170*9001.
Step 6
Press Validate to save the setting.
Note
And eye icon appears on the idle screen to indicate that logging has been
enabled for the phone.
Step 7
On the server that will receive information, open a command window and type the
following command:
prserv
[listen_port]
where listen_port is the same port that you specified with the Nprintf parameter.
If you do not specify a port, 9001 is used by default.
While prserv is running, information from the Cisco Unified IP Phone is sent to a
file named listen_port.log, where listen_port is the port you specified with the
Nprintf parameter and the prserv command. This file is stored on the server you
specified with the Nprintf parameter in the folder from which you ran the prserv
command. If the file exists, new information is appended to it.
You can open a listen_port.log file using a text editor.
Step 8
To exit prserv.exe and stop collecting information, press Ctrl-C in the command
window.
