Hi Clement,


  I'm sorry for the tool. We are still working on the project, so we
need documentation
fot it. But, to compile the tools you will need:

#   gcc -lm fatorIe.cc -o markov
#   gcc -lm fatorR.cc -o mos


   That's what you need! Now do some calls generating the trace file.

#   linphonec -q trace.log

   Assuming that you have patched linphone 1.0.1. So,  get the speech quality
(MOS):

#  markov trace.log > trace.mkv
#  mos trace.mkv



   This will output your incomming RTP flow MOS points (As you know 1~5).

   I will apreciate your comments.
