[asterisk-users] packet loss stats - how does asterisk know about packets sent % lost ?

[Kevin Long]

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!
