Astersk CDR data from leg B

I’m using cdr_adaptive_odbc module to collect RTCP data of the call to table.
More or less it looks like this:


; usual Dial

same => n,Set(CHANNEL(hangup_handler_push)=qos_leg_a,s,1)

same => n,Dial(${destinationStr},,b(set_qos_handler_b^s^1))

exten => s,1,Noop(Channel: ${CHANNEL(name)}, QoS stats RTCP: ${CHANNEL(rtcp,all)})
    same => n,Set(CDR(sip_callid)=${CHANNEL(pjsip,call-id)})
    same => n,GotoIf($["${CHANNEL(rtcp,all)}"==""]?end)
    same => n,Set(CDR(rtcp_a_all)=${CHANNEL(rtcp,all)})
    same => n,Set(CDR(rtcp_a_all_jitter)=${CHANNEL(rtcp,all_jitter)})
    same => n,Set(CDR(rtcp_a_all_loss)=${CHANNEL(rtcp,all_loss)})
    same => n,Set(CDR(rtcp_a_all_rtt)=${CHANNEL(rtcp,all_rtt)})
    same => n(end),Return()

exten => s,1,Noop(Channel: ${CHANNEL(name)}, QoS stats RTCP: ${CHANNEL(rtcp,all)})
    same => n,GotoIf($["${CHANNEL(rtcp,all)}"==""]?end)
    same => n,Set(CDR(rtcp_b_all)=${CHANNEL(rtcp,all)})
    same => n,Set(CDR(rtcp_b_all_jitter)=${CHANNEL(rtcp,all_jitter)})
    same => n,Set(CDR(rtcp_b_all_loss)=${CHANNEL(rtcp,all_loss)})
    same => n,Set(CDR(rtcp_b_all_rtt)=${CHANNEL(rtcp,all_rtt)})
    same => n(end),Return()


exten => s,1,Set(CHANNEL(hangup_handler_push)=qos_leg_b,s,1)
    same => n,Return()

It works like a charm if you have in ${destinationStr} something like PJSIP/${EXTEN}. But when it’s a complex string, like PJSIP/${EXTEN}&Local/whatever@else I see commands are running on a legB, but no CDR extra data is being written to the table. For A leg it’s all fine, but not for B. It’s just setting NULL for all legB data, although I can see in the dialplan variables are set.

What hints are possible here to get this info in database without additional external scripting (which is possible, but adding extra layer)?

Did you notice any difference between answering by Local channel and PJSIP using PJSIP/${EXTEN}&Local/whatever@else ?

Actually for me Local/whatever@else is never answering. It consists only on one NoOp(), but it’s needed for some other tricks (2-stage early-media, I described here).
So it’s always PJSIP/${EXTEN} is answering.
