For example the acutal average of propogation time inside Internet is ~0.15 second without collision or "bouchon" at all. If you want to execute all sond and video buffering to limit jitter under 0.25 s (standard) of time shifting between phone or videophone user, I think you do it make somme attention with this problem. The administrator of network of "Etat de Vaud" use QoS for ~1500 IP Phones inside there network. I thing it is for a good raison and the QoS for this network is totally under control of this administration. That is probaly not the case for majority of other people. > QoS only affect queuing time. Try to use a power backup of big file transert in 10 Mbs local net at the same time to use OpenH323, I think you can have some problem without QoS. In other side some task like monitoring of server activity can be detect dead of server in this case. In fact if you use VoIP only in your local network and you don't have any big transfer in your network you can try without QoS.
