Description
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.
