I recently purchased and have been reading through Integrating Voice and Data Networks by Scott Keagy, available from CiscoPress. I must say that this is a truly excellent book and I wish I'd had this months ago. It would have saved me from learning a lot of lessons the hard way.
It does a great job of explaining various voice technologies and WAN design considerations. It has some wonderful sections of codecs and how to choose the right one for your application. Especially helpful to me is the section on frame relay which has a great explanation of FRTS. I'm only about a third of the way through the book and I've learned stuff already that we immediately applied to our network to improve our VoIP quality. If you're in the market for a good book on Voice-over-whatever, you must buy this book.
