An unused eticket can't be converted to a voucher. It's an eticket. Viychers and unused etickets both are "ecredits." Thus confusion people have as DL keeps saying your eticket "becomes" an ecredit. There's no such thing as an ecredit, it's simply an overall name for vouchers and unused etickets. AA at least refers to these as different things "flight" and "travel" credit instead of simply as ecredit.
Eticket can only be used by passenger named.
