hello, every body, I see in rfc2543 that servers and UACs may send request via multcast address and when the next downstream hop response this request, it will send it back via the multicast address derived from the via headers of the request. but how could the upstream hop receive the response if it's not a member of this multicast group?
thanks a lot for any information. lei
