1. Welcome to CVOICE 8.0: Cisco Certification and Getting the Most from this Series
Welcome to the Cisco CVOICE video series! This opening Nugget discusses the series objectives and their relation to the Cisco CCNP Voice certification path. You'll also see recent changes to the Cisco certification process that make real-world training (which is the goal of CBT Nuggets) the best possible way to prepare.

14. Advanced Dial Plans: Calling Privileges with Class of Restriction (COR)
This Nugget covers the implementation of calling restrictions using the Class of Restriction (COR) lists feature of Cisco voice gateways. Topics include the purpose of calling restrictions, reconstructing PSTN dial-peers, and understanding and implementing COR Lists.
00:34:14

15. CME: IP Phones, VLANs, and Communication
This Nugget discusses the characteristics of Cisco IP Phones (allowing you to pick which model suits you)000, presents an understanding of key network configurations needed to support Cisco IP Phones (Voice VLAN, Quality of Service (QoS), DHCP, and Power over Ethernet (PoE)), and the IP Phone boot and registration process.
00:35:15

16. CME: Base Configuration
This Nugget walks through the base configuration needed to support IP Phones using CME: Power over Ethernet (PoE), Voice VLAN (VVLAN), Network Time Protocol (NTP), DHCP, IP Phone Firmware, telephony-service (SCCP) configuration, and SIP configuration.
00:39:28

17. CME: Ephones and Ephone-DNs, Part 1
This Nugget builds on the base configuration in the previous Nugget to configure Ephone and Ephone-DNs, making internal VoIP calling possible.
00:28:33

18. CME: Ephones and Ephone-DNs, Part 2
Picking up right where the last Nugget left off, we break down the "button" command and perform multiple examples of shared lines, button overlay, and auto-assignment.

25. Quality of Service: The Missing Ingredient
Without Quality of Service (QoS), your voice network will quickly crumble under the iron fist of data traffic. In this Nugget, Jeremy identifies the "Evil Villains" (delay, jitter, and packet loss) of the voice network and breaks down the different QoS tools you have at your disposal to handle them. The Nugget concludes with a configuration walk-through of the Modular QoS CLI (MQC) structure (class-map, policy-map, service-policy).
