Huh??? Not in my experience. Cancel a ticket. Get a credit on file with UA for the amount of that ticket. When you book a new ticket they apply that amount minus the change fee. Done it dozens of times. Don't get any vouchers. Never had to pay the change fee in cash up front, never! Oops, used that word, never. I have not at any time had to pay the change fee in cash up front.
Edit to add, just did it this past Tuesday.
