Hi, Jorge –


Make sure your media server supports RTCP/XR (RFC-3611 at http://tools.ietf.org/html/rfc3611).  Those are the Extended Reporting packets that contain information like the number of packets, the number of lost packets and (see http://tools.ietf.org/html/draft-ietf-xrblock-rtcp-xr-qoe-17) the MOS score.  Look at the Statistics Summary Report Block for jitter information, too.  Use Wireshark to see what is available from your media server.  See also RFC-6792, http://tools.ietf.org/html/rfc6792.

Dear All,

I would like to know if you can recommend me an opensource platform or any other good for the price that i could use to gather RTCP packets information in order to monitor voip call quality. We do not proxy the calls (no RTP will be gather by the platform) in order to optimized bandwidth usage. We plan to do this installing the recommended platform in a standalone server and then configure a restricted SSH user into the media servers and capture the information by TCPDUMP permanent filter.

Please let me know if you have any recommendation.

Thanks a lot
