[asterisk-users] packet loss stats - how does asterisk know about packets sent % lost ?
Hello, I am just wondering if the statistics from the ?sip show channelstats? and ?pjsip show channelstats? command are reliable indicators of packet loss. How does asterisk know how many packets *sent* were lost? Does this require RTCP compatible endpoint/phone, or something else? Thanks! Kevin Long

The number is accurate so long as Asterisk is receiving RTCP information from the endpoint(s) in question.
