Title: Good book for IP Telephony support engineer
Review: This is a good book for up to date IP telephony support engineer. However, this book is a bit annoying to me when I just pick it up and read because of its high-light format is backward compare with Ciscopress traditional format. High-light should be on the IOS commands in the example box like the rest of Ciscopress books instead of on the notes decorative lines. Beside this annoying format this is a great book.
