What the detail says

The detail explains the occurrence; it can read, for example:

• Nexafon has no Meta access for this number, so it cannot change its calling. Connect the number again.

Handling it

The current state does not allow this; read it again before retrying.

Match on code, never on detail: the wording may change. See Problem Details.
