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:

identity from a corporate directory, and registration restriction to control which of those authenticated
endpoints may register with a particular VCS.

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.

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.

Endpoints that are not traversal-enabled can still register with a VCS Expressway, but they may not be able
to make or receive calls through the firewall successfully. This will depend on a number of factors:
