Which CSS allows a call to reach a specific partition?

• A. Partition-specific route
• B. Route Group
• C. CSS containing the partition
• D. Calling Search Space

Answer: (C)

In CUCM, reachability of a route is governed by the calling search space that the caller uses. The CSS is the set of partitions the device is allowed to search when dialing. For a call to reach a specific partition, that partition must be included in the caller’s CSS. If the partition isn’t in the CSS, CUCM won’t search that partition and the corresponding route pattern won’t be found, so the call won’t route to that destination. So, the CSS containing the partition provides the path that allows the call to reach that partition. The other terms describe different routing concepts, but they don’t define the actual search path needed to access a particular partition.
