Problem with RTCP

Asterisk Asterisk Support
1

At the analysis of RTCP-packages has faced such problem: in a field “Jitter” are only “0” and in my program I show “Jitter = 0” but it is wrong in log of RTCP Jitter > 0.

Log of Asterisk:
RTP-stats

  • Our Receiver:
    SSRC: 3231147159
    Received packets: 1125
    Lost packets: 0
    Jitter: 0.0234

    RR-count: 0

    RTT: -13035.689434

In this log " Jitter: 0.0234 " - how I can get this value?

What is your program? Are you using something external to ASterisk to collect RTCP reports?
