FS would then record it and then, by comparing the recorded and the original one and using some signal processing, you can compute a MOSPESQ figure.</div><div><br><div>

</span><span style="font-size:medium"><span>I am thinking of a way of testing the quality of a voice call. </span></span><span style="font-size:medium"><br></span><span style="font-size:medium"><span></span></span><span style="font-size:medium"><br>
</span><span style="font-size:medium"><span>Ideally i would like to create a call from FS with a loopback parameter that tells phone to answer the call automatically and loopback the RTP. This is a common functionality in most phoned (for example cisco)</span></span><span style="font-size:medium"><br>
</span><span style="font-size:medium"><span>The sent and received packets could be compared for jitter, latency and packet loss and a result extracted.</span></span><span style="font-size:medium"><br></span><span style="font-size:medium"><span></span></span><span style="font-size:medium"><br>
</span><span style="font-size:medium"><span>Does this already exist? I know there some specific tool that accomplish this bit they are expensive and awkward to use. Starting and retrieving the result from an api would be fantastic.</span></span><span style="font-size:medium"><br>
