Paul,

You changed the text for the term multicast, but in H.323 the term is
used also for T.120 which sends PDUs (see section 6.2.7)

So maybe it is not an error

Paul,

This works in point to point and I am not sure why you need multicast in
this case. Also you are not doing multicast H.245. So there is an MC

Now let's take the case of an MC that has three participants in the
multicast group.

The first one sends an OLC with payload type 100. The second one sends
an OLC with payload type 101 and the third with payload type of 102. Now
the MC needs to send an OLC to the first participant, which payload type
should it use 101,102,100?

Roni,

 

I guess I am still missing your point.  This is a means of sending
media, just like unicast.  The payload type numbers are selected by the
sender, just as they are for unicast.  If the recipient accepts the
proposed OLC, then it would listen on the multicast address for incoming
media accordingly.

Paul,

Is the multicast uni-directional, is it just a point to point. If it is
to be used to enable the EP to send media to a multicast group this
should be aligned with the media the other side except to receive. How
does it get set

Roni,

 

I don't understand your concern.  Can you clarify the problem?

 

Paul

Hi,

I looked at the document and I think I understand the OLC procedure. I
need it does not address how you decide on a dynamic payload type number
when needed.

The OLC gives the dynamic payload type number to send
