Hi I am trying to get RTP stats like R-factor and MOS numbers. PJSIP seems to have support for it using RTCP Extended Report module. I have set to 1 both PJMEDIA_HAS_RTCP_XR and PJMEDIA_STREAM_ENABLE_XR but when I start collecting stats R-factors and MOS numbers are 127 (n/a). Could you tell me how can I enable in PJSIP this module ? thanks Bogdan
