workspace_call_link_invalid
HTTP 404§9.17 The customer team workspace on the phone (`/v1/mobile/workspace/*`, `/v1/mobile/voice/token`)
A record named for the call (task_id, opportunity_id, case_id, callback_id, missed_ticket_id) does not exist, is not yours to open, or is not about this customer - deliberately indistinguishable. Nothing was reserved, dialed or saved.
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.
