[Freeswitch-users] advise to troubleshoot a call

[Michel Brabants]

RTCP provides you normally with statistics that can help you. I didn't
check it in freeswitch yet, but there is an option to enable it (not
standard apparently?) in the profile. One step further is rtcp-xr which can
provide mos-score, but with all of this, the receiving endpoint should also
support this.

Kind regards,

Michel
