Which system location is used for intercluster Enhanced Location CAC on Cisco Unified
Communications Manager?

A.
Hub_None

B.
Default

C.
Intercluster

D.
Phantom

E.
Shadow

Explanation:
Theshadowlocationis used to enable a SIP trunk to pass Enhanced Location CAC

information such as location name and Video-Traffic-Class (discussed below), among other things,
required for Enhanced Location CAC to function between clusters. In order to pass this location
information across clusters, the SIP intercluster trunk (ICT) must be assigned to the “shadow”
location. The shadow location cannot have a link to other locations, and therefore no bandwidth
can be reserved between the shadow location and other locations. Any device other than a SIP
ICT that is assigned to the shadow location will be treated as if it was associated to Hub_None.
That is important to know because if a device other than a SIP ICT ends up in the shadow
location, bandwidth deductions will be made from that device as if it were in Hub_None, and that
could have varying effects depending on the location and links configuration.
