 Precedence This is the default mode and is capable of providing priority services to all
types of routers, as well as being currently the most common mechanism. Use this option
when the network router uses Precedence for priority encoding, or when you are not sure
which method is used by the router. Precedence needs to be combined with None in the
TOS field. The default priority is 5 for audio and 4 for video packets.
Audio / Video You can prioritize audio and video IP packets to ensure that all participants in
the conference hear and see each other clearly. Choose a scale from 0 to 5, where 0 is the
lowest priority and 5 is the highest. The recommended priority is 4 for audio and 4 for video to
ensure that the delay for both packet types is the same and that audio and video packets are
synchronized and to ensure lip sync.
 TOS Choose the type of service (TOS) that defines optimization tagging for routing the
conferences’ audio and video packets. Choose from the following options:
 Delay The recommended option for video conferencing. Prioritized audio and video
packets tagged with this definition are delivered with minimal delay because the throughput
of IP packets minimizes the queue sequence and the delay between packets.
 None No optimization definition is applied. This is a compatibility mode in which routing is
based on Precedence priority settings only. Select None if you do not know which standard
your router supports.
