The original idea was that only endpoints send ARQ. An MC is not an endpoint, however, it is a
functional element which can be contained in an endpoint (such is the case of an MCU or a terminal
which contains an MC). So even though the endpoint contains an MC, it is the endpoint which is
sending the ARQ not the MC functional element.

If an MC exists in the Gatekeeper, I do not beleive that that MC will ever send ARQ for any of the
connections in the conference. Only the endpoints in that conference will send ARQ to their
