Hi Srikanth,

The error indicates you likely have no app_unimrcp module installed.

What is the output of

module show like app_unimrcp.so

I am not sure how you installed the modules, but make sure the .so files are getting installed to the intended directory. Please look for similar posts on the discussion group.

    *CLI> module load  app_unimrcp.so

Check for any errors output on the loading of the app_unimrcp module and you will find out the problem.

Hello Arsen,

I tried to load and reload the module. I didn't get any error messages while doing. Could you please let me know the possible cases OR solutions that can resolve this issue?

Hello Srikanth,

The most typical problem is in a wrong or already occupied local IP address/port specified in configuration.
