Default IP Service – Conferencing – QoS Parameters

Field

Description

 

 

Audio / Video

You can prioritize audio and video IP packets to ensure that all participants in

 

the conference hear and see each other clearly. Select the desired priority. The

 

scale is 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

Select the type of Service (TOS) that defines optimization tagging for routing the

 

conferences audio and video packets.

 

• Delay: The recommended default for video conferencing; prioritized audio

 

and video packets tagged with this definition are delivered with minimal delay

 

(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.
