Pjsip rtcp statistics

I am looking at switching from chan_sip to pjsip, and I cant find the equivalent of :

My guess is that it would be : ${CHANNEL(rtcp,statistic,all)} , but this fails.

Any ideas ?

Anyone has an idea ?

According to the wiki page[1] it would be ${CHANNEL(rtcp,all)} for all statistics and I think ${CHANNEL(rtcp,all,audio)} for audio only.
