To configure the ports used for media in traversal calls, go to
Subzone.
You must ensure that the port range is large enough to support the maximum number of traversal calls
available on your VCS. A single traversal call can take up to 40 ports. So for example, if your VCS is licensed
for 5 traversal calls you must ensure that the range of ports configured for traversal media is at least 200. If
you add extra traversal call licenses to your system, you must also ensure that the range of ports available is
sufficient.

restrictions on calls involving endpoints in the Default Subzone, and to specify the Default Subzone's
registration, authentication and media encryption policies.
When an endpoint registers with the VCS, its IP address and alias is checked against the subzone
membership rules and it is assigned to the appropriate subzone. If no subzones have been created, or the
endpoint's IP address or alias does not match any of the subzone membership rules, it is assigned to the
Default Subzone (subject to the Default Subzone's Registration policy and Authentication policy).
The use of a Default Subzone on its own (without any other manually created subzones) is suitable only if
you have uniform bandwidth available between all your endpoints. Note that if your Local Zone contains two
or more different networks with different bandwidth limitations, you should configure separate subzones for
each different part of the network.

configured on the VCS, and allows you to create, edit and delete subzones. For each subzone, it shows how
many membership rules it has, how many devices are currently registered to it, and the current number of
calls and bandwidth in use. Up to 1000 subzones can be configured.
After configuring a subzone you should set up the
an endpoint device is assigned to when it registers with the VCS as opposed to defaulting to the
Subzone.
