About Registrations
For an endpoint to use the VCS as its H.323 gatekeeper or SIP registrar, the endpoint must first register with the VCS.
The VCS can be configured to control which devices are allowed to register with it by using the following
mechanisms:
The VCS can be configured to control which devices are allowed to register with it by using the following
mechanisms:
■
■
or an external policy service to specify
which aliases can and cannot register with the VCS
■
restrictions based on IP addresses and subnet ranges through the specification of subzone membership rules
and
and
You can use these mechanisms together. For example, you can use authentication to verify an endpoint’s identity
from a corporate directory, and registration restriction to control which of those authenticated endpoints may register
with a particular VCS.

You can also control some protocol-specific behavior, including:

deployment, endpoint registration for SIP devices may be provided by Unified CM. In this
scenario, the VCS provides secure firewall traversal and line-side support for Unified CM registrations. When
configuring a domain, you can select whether Cisco Unified Communications Manager or VCS provides registration
and provisioning services for the domain.

Finding a VCS With Which to Register
Before an endpoint can register with a VCS, it must determine which VCS it can or should be registering with. This
setting is configured on the endpoint, and the process is different for

Registrations on a VCS Expressway
If a traversal-enabled endpoint registers directly with a VCS Expressway, the VCS Expressway will provide the same
services to that endpoint as a VCS Control, with the addition of firewall traversal. Traversal-enabled endpoints
include all Cisco TelePresence Expressway™ endpoints and third-party endpoints which support the ITU H.460.18
and H.460.19 standards.
