Explanation

In Cisco Unified Communications Manager (CUCM), when a call is placed, the Calling Search Space (CSS) configured at the Directory Number (DN/line) level always takes precedence over the CSS configured at the device (phone) level. This is a core CUCM design principle: line-level settings override device-level settings for call routing. Therefore, 'Directory Number Configuration > Calling Search Space: CSS_Locales' (C) has the highest priority. The phone-level CSS only applies if no CSS is configured at the line level.
