Calculating MOS, Jitter and R-Factor using Java

I need to calculate the VOIP quality by sending synthetic calls between two hosts (2 Java Processes). I should find out the MOS, Jitter and R-Factor (VOIP Quality metrics). Based on the research so far, I found out that I should send RTP stream between two hosts and compute the above mentioned metrics. I couldn't find an example or a library that I can use to send RTP data using java and more precisely a library that can compute those metrics. Any help in this is really appreciated.

Thanks.

You can extract the jitter, latency and packet loss from the receiver reports in your RTCP packets.

The R-Factor can be calculated from those RTCP values as decribed in the G.107 standard.

MOS is a subjective scale that you can't measure, but there are known MOS values for certain audio codecs.
