Explanation

In Cisco Unified Communications Manager (CUCM), a Calling Search Space (CSS) is assigned to originating devices or lines to control which partitions-and therefore which directory numbers and route patterns-they are permitted to call. Phones (A) are assigned a CSS so CUCM knows which partitions the phone can dial. Gateways/trunks (C) also have a CSS to restrict or permit which destinations inbound calls from the PSTN can reach. Partitions (B) are the destinations organized into logical groups, not originators, so they do not have a CSS. Transcoders (D) and AAR groups (E) do not use CSS in the same originating-device role.
