Add-On Selling. How to squeeze every last ounce of sales potential from your calls. Jim Domanski. 2002. ISBN1881081117. You may not have heard of this Canadian telesales expert, but you should. He is one of the businessbyphone.com authors and I received this and two other books in a clear out set from them. What a bargain! Not only does he cover add-on, cross-sell, upselling on the phone, he has sections for converting  inquiries, cancellations, complaints, customer service calls into sales. His approaches are just as useful face to face. A no nonsense straightforward easy read, this is a library keeper. His section on getting leads and referrals is bang on the money.
