Configuring Subzones
The Subzones page (Configuration > Local Zone > Subzones) lists all the subzones that have been 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.

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.

to control whether an endpoint can register with
the VCS, you can also configure a subzone's Registration policy as to whether it will accept
registrations assigned to it via the subzone membership rules.
registrations assigned to it via the subzone membership rules.
This provides additional flexibility when defining your registration policy. For example you can:
■
Deny registrations based on IP address subnet. You can do this by creating a subzone with
associated membership rules based on an IP address subnet range, and then setting that
subzone to deny registrations.

Configure the Default Subzone to deny registrations. This would cause any registration
requests that do not match any of the subzone membership rules, and hence fall into the
Default Subzone, to be denied.
