Hello! I tried to get answer from implementors group and some other person, but I couldn't get any satisfiable answer. My question is here. In section 8.4.3.2(Figure 28/H.323-Non-MC invite signalling), when an endpoint(E1) which do not have active MC wants to invite other endpoint(E3), does E1 send an ARQ to its Gatekeeper for the invite or does E2 send the ARQ to its gatekeeper, or do both of them send ARQ's? And, when Gatekeeper doesn't know which endpoint has active MC in any conference, … [View More]
