shared_phone_pickup_unavailable
The waiting caller cannot currently be picked up by this teammate. Refresh the queue and check verified phone, availability and the returned reason; do not assume a new call was connected.

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.
