Debugging IP Phone no Audio

Background

While troubleshooting no audio problems with IP phones it may come in handy to enable an rtp debug directly on the ip phone. This other document explains how to login to an ip phone for debugging.

Enable the Debug

First access debugsh mode.

$ debugsh

With the keyword debug you can display the different debugs available at the ip phone.

For this specific case we would like to enable the following debugs.
0021555384FA> debug dsp rtp
        Sending SIGUSR2 to dsp
0021555384FA> debug jvm MediaManager
0021555384FA> debug jvm SCCP
/usr/local/trace/log.propertiesSuccessfully executed the command.
After you have enabled the debugs that interest you, exit the debug subsystem by quitting.
0021555384FA> quit
/usr/local/trace/log.propertiesSuccessfully executed the command.Exiting shell...
Logging out...
Use the command strace to begin the debugging session. The following is an example of the output.
$
$ strace
strace: PID = 23, ver A
