Not a single book,
but you might want to read stuff from Integrating Voice & Data Networks &
Cisco Voice over IP, FR, ATM (both are cisco press books). I found the first

2nd one is the course book, and as all course books are it explains the
subject from a Cisco point of view (all commands and explanaations blah)
