A common way to test audio quality is to have a device (sipp for instance) calling your FS and playing a known audio file. 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.

Hi all, I am thinking of a way of testing the quality of a voice call.
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) The sent and received packets could be compared for jitter, latency and packet loss and a result extracted.
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.
Any ideas are welcome.
