Hi,

other devices (like FritzBox from AVM) report quality parameters in a proprietary SIP header "X-RTP" in the BYE/ OK during call ending which can be easily read from the proxy. This values are generated from the RTCP as well, but they naturally did not provide a complete look to all of this parameters.
