How to get the all rtcp value from the asterisk

Actually i am trying to get the rtcp value from the asterisk and i have tried it in extension.conf but not able to do that please help and i want all the value in rtcp like min max avg jitter latency rtt all of that

For absolutely all the values, enable RTCP debugging and monitor the logs.

chan_sip has channel variables for this, but I don’t know what arrangements there are for chan_pjsip.
