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

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.

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, 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, The proposal is limited to the case where multicast is used when a MC does not exert control over the conference. That is, when two devices are in a point-to-point call. One example of where this is useful is when a PBX wants to put a call on hold and "music on hold" is broadcast by a server to all devices that are on hold. In this case, for example, a PBX (or phone) might send a TCS=0 to the held party and then send an OLC proposing a multicast address. Any use of multicast that involves an MC (or transmission of the communication mode table) is outside the scope of this proposed addition and is already addressed by H.323.

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 Roni ________________________________ From: itu-sg16-bounces@lists.packetizer.com [mailto:itu-sg16-bounces@lists.packetizer.com] On Behalf Of Even, Roni Sent: Tuesday, January 29, 2008 7:25 PM To: Paul E.

Roni, I captured this point in the Q2 meeting report. Indeed, multicast PDUs and media might be sent. So, the definitions would allow for either media or PDUs.
