I just did this a week ago.
I put an itin on hold on the website, called UA to tell them I needed to ticket it using a voucher (actually a travel credit from a fare drop), gave the CSR the credit card info. Sent it to Dearborn; ticketed 8 days later.
I also used a CS$25 discount cert but I didn't even bother to mention that on the phone, because I've had little luck explaining to the phone CSRs that a Type A and a Type B are in fact combinable. Rather, I enclosed it along with a letter pointing out that Type A and B certs were combinable and if they had any questions to call me.
One thing that speeds it up a bit is to say that you'd like the reservation ticketed as early as possible so you can apply for upgrades.
