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!

  • The number of packets lost is determined based on RTCP information received from the far endpoint. The number is accurate so long as Asterisk is receiving RTCP information from the endpoint(s) in question.
