Ok I see it now. Indeed the responses are never propagated. I can tell from the record routes taht your unmanaged gateway is another sipx. I do remember posts in the past from the old maintainers that 302 initiated by a third party is not advisable because it may conflict with sipx internal routing. That could be causing this glitch. If you want to tackle this even further, feel free to send in the DEBUG level proxy logs. perhaps it will tell more as to what really transpired with those missing packets.

    From what i saw, the capture does not make any sense.  I don't see
    the 183 and the 200 you were mentioning.

    I've just start a preliminary work on this issue, and i start
    working on this use case:

    call forwarding to external number,

    so A, B and C where C is not local extension, reachable through
    an unmanaged gateway (so without sbc)

    what i see is that:

    A call B,
    B sends 302 to A but this message is handled by the proxy that
    creates a new invite for C
    C reply to invite with 183 and then with 200 ok but none of this
    messages are forwarded to A


    as consequence in the cdr we have just a not connected call.

    here I attach the related pcap to this scenario just to be sure
    the the source isn't into some wrong config
