Refer to the exhibit. Which statement is true?
A. Endpoints can make calls to unknown IP addresses without the VCS querying any neighbors.
B. If the VCS receives a call to an unknown IP address, it queries its neighbors for the remote address and if permitted, it routes the call through the neighbor.
C. Endpoints that are registered directly to the VCS can call only an IP address of a system that is also registered directly to that VCS.
D. Dialing by IP address is not supported on VCS.
-Direct: allows an endpoint to make a call to an unknown IP address without the VCS querying any neighbors. The call setup would occur just as it would if the far end were registered directly to the local system.
-Indirect: upon receiving a call to an unknown IP address, the VCS will query its neighbors for the remote address and if permitted will route the call through the neighbor.
-Off: endpoints registered directly to the VCS may only call an IP address of a system also registered directly to that VCS.
Default: Indirect
