Appendix A Additional Configuration Methods, Parameters, and Procedures

Collecting Information for Troubleshooting

Step 2 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 pserv is running, information from the Cisco IP Phone is sent to a file named listen-port.log, where listen-portis 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 preserv command. If the file exists, new information is appended to it.

You can open a listen-port.log file using a text editor.

Step 3 To exit prserv.exe and stop collecting information, press Ctrl-Cin the command window.
