You try to register a new H.323 endpoint to a Cisco VCS server, but the endpoint does not register correctly. You successfully check network connectivity and VCS registration with other devices. Which issue and solution will resolve this registration problem?
A. Cisco VCS Server H.323 service must be restarted to activate the new endpoint.
B. The Registration Policy is set to "Deny List" so all new endpoints are rejected. Set the Policy to "Allow List" so that the endpoint can register themselves and then reassign the "Deny List" Setting for security reasons.
C. The new endpoint has not been assigned with the correct registration domain, so configure the correct domain on the endpoint.
D. The Registration Policy is set to "Allow List" and the newly added endpoint has to be added to the list, because only listed devices are allowed to register.
