receive and deliver better quality and more reliable video during calls. However, they might not
receive video on incoming calls received from video endpoints for normal users because
● No bandwidth is available
● No normal bandwidth is available even though priority bandwidth is available. The call is
made by a normal video endpoint, and this endpoint did not have access to the priority
bandwidth.
Bandwidth pools
For H.323, you can categorize users by audio-only, normal video, and priority video users,
dividing them into three pools:
● Audio—The audio pool contains bandwidth for all audio calls, including the audio
component of multimedia calls.
● Normal video—The normal video pool contains bandwidth for the video portion of a call
made by a normal (nonpriority) video user. You can set this pool to be shared. When this
pool is shared, audio-only calls are allowed to borrow bandwidth from this pool.
● Priority video—The priority video pool contains bandwidth that is dedicated to priority video
users only. Audio calls and normal video users are not allowed to borrow bandwidth from
this pool. However, if all of the priority video pool bandwidth is currently in use, priority
video users can borrow bandwidth from the normal video pool, if available.
The following tables provide examples of how you might specify the bandwidth settings for your
network. See Setting up bandwidth pools
on page 34 for how to administer these pools through
Network Regions.

In this example, you do not want to allocate any bandwidth for video.
You want to configure the network to use audio. Bandwidth settings for audio only
shows how
you would configure the bandwidth groups for this example.
Example 2: Video for all - In this example, your network has enough bandwidth to support
video for all users simultaneously. Because all of your users can get as much bandwidth as they
need, there is no need to specify priority users. Only one group of bandwidth is shared by audio
