Recommended Study Resources
For self-study, several Cisco Press titles can help you prepare for various topics covered on the CCIE Voice Written exam:
A foundational book you might want to read first is Voice over IP Fundamentals, 2nd Edition. This book introduces VoIP basics, including a discussion of signaling protocols, VoIP security, and quality of service (QoS) issues.
You might then consider the some of the books which map to the courses in the new CCNP Voice curriculum:
The Implementing Cisco Unified Communications Voice over IP and QoS (Cvoice) Foundation Learning Guide, 4th Edition book (scheduled for release in May 2011) maps to the new CVOICE 8.0 course, which focuses on the configuration of gateways, gatekeepers, and Cisco Unified Border Elements (CUBEs).
Cisco Unified Communications Manager and its myriad of features are addressed in two courses (CIPT1 and CIPT2). Books mapping to those courses include Implementing Cisco Unified Communications Manager, Part 1 (CIPT1) Foundation Learning Guide. 2nd Edition (scheduled for release in June 2011) and Implementing Cisco Unified Communications Manager, Part 2 (CIPT2) Foundation Learning Guide, 2nd Edition (scheduled for release in June 2011).
If you read this before the CVOICE, CIPT1, or CIPT2 are released, you can still purchase the Rough Cut Edition of these books directly from Cisco Press.
For Cisco Unified Presence Server study, I recommend Cisco Unified Presence Fundamentals.
While you might not be able to find any hardcopy book focusing on Cisco Unified Contact Center Express (UCCX), you can certainly turn to Cisco’s Product Documentation page for UCCX.
The Cisco Learning Network also has a list of recommended study resources you might want to check out.
