This Recommendation defines a package that provides RFC 3611's RTP Control Protocol Reporting Extensions (RTCP XR) metrics reporting capabilities for ITU-T Rec. H.248 that provide more detailed insight into call quality and causes of degradation than basic RTCP statistics.

Edition 2 adds a new package and modifies the existing package to allow the support of reporting RTCP XR statistics from both directions of a bidirectional RTP session controlled through RTCP.
