contact_center_not_enabled
The contact center (or, for queue routing, its contact_center_routing sub-switch) is not turned on for this company - a staff-set entitlement, off by default in production. Lines keep ringing their teams as today; Available / Not ready / Offline with the built-in reasons work regardless. Nothing changed.
Problem shape
Every non-2xx response is an RFC 9457 application/problem+json body. The type URI below is stable and machine-matchable, so branch on the final path segment (the code) and treat the status as redundant confirmation. See the error-handling guide.
