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-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 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-C in the command
window.
