vocapablecc_pci_payment_line_unavailable
A payment line cannot be used this way: the payment pause is off for the company, the recording could not be confirmed paused (the line was not dialed), or it was named as a transfer target (add it to the call instead).
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.
