About subzones
The Local Zone is made up of subzones. Subzones are used to control the bandwidth used by various parts
of your network, and to control the VCS's registration, authentication and media encryption policies.

Default links between subzones
The VCS is shipped with the Default Subzone and Traversal Subzone (and Default Zone) already created,

also established automatically. You can delete or amend these

About the Traversal Subzone
The Traversal Subzone is a conceptual subzone. No endpoints can be registered to the Traversal Subzone;
its sole purpose is to control the bandwidth used by

used for the media in traversal calls.
Configuring bandwidth limitations
All traversal calls pass through the Traversal Subzone, so by applying bandwidth limitations to the Traversal
Subzone you can control how much processing of media the VCS will perform at any one time. These
limitations can be applied on a total concurrent usage basis, and on a per-call basis.

Configuring the Traversal Subzone ports
On
Configuration > Local Zone > Traversal Subzone
you can configure the range of ports used for media
in traversal calls.
What is a valid range to use?
You can define the media port range anywhere within the range 1024 to 65533. Traversal media port start
must be an even number and Traversal media port end must be an odd number, because ports are
allocated in pairs and the first port allocated in each pair is even.
