CVOICE 8.0 is a new VoIP world! Join trainer Jeremy Cioara on a CCNP Voice journey.
This course maps to the 642-437 exam, the first step towards CCNP Voice certification. You'll learn the critical foundational skills necessary to build a VoIP system. Without the knowledge from this course, you’re building your voice network on sand that will quickly wash out from under you!
With the addition of Cisco Unified Communication Manager Express (CUCME) in the new CVOICE 8.0, you can build an entire VoIP systems for a small-to-midsize office. Previous versions of CVOICE were never this cool!
This course is perfect for those aiming for a CCNP Voice certification, those looking to move to a VoIP system, and anyone who isn't afraid to get down and dirty with VoIP configurations.
[wpspoiler name="Подробное описание" ] 1. Welcome to CVOICE 8.0: Cisco Certification and Getting the Most from this Course (00:21:41)
Welcome to the Cisco CVOICE video series! This opening Nugget discusses the course objectives and their relation to the Cisco CCNP Voice certification path.

8. Dial Peers: Understanding and Using Dial-Peers (00:43:46)
This Nugget discusses the concept of Cisco Call Legs, the differences between POTS and VoIP dial-peers, and performs a base configuration of POTS/VoIP dial-peers on two Cisco routers.
9. Dial Peers: Wildcards and Voice Route Matching (00:33:12)

10. Dial Peers: End-to-End Practical Scenario (00:46:15)
This Nugget is subtitled, "How to Set up Your House for VoIP." Jeremy puts together a complete demonstration from scratch covering the following topics: Bringing a PSTN line into an FXO port, FXS configuration, PSTN dial-peers, Private Line Automatic Ringdown (PLAR), automatic digit stripping (POTS dial-peers), forward-digits, VoIP dial-peers, and CODEC modification.
11. Dial Peers: Overlapping, Hunting, and Basic Manipulation (00:22:58)
This Nugget discusses the methods routers use to handle overlapping dial-peers and duplicate destinations, dial-peer hunt options, creating hunt groups, and basic digit manipulation commands (prefix, forward-digits, num-exp).
12. Advanced Dial Plans: Digit Manipulation and Transformation (00:37:58)
This Nugget discusses methods used to modify Caller-ID (ANI) information, translation-rules, and provides many examples of regular expression use with called and calling transformations.
13. Advanced Dial Plans: Configuring, Applying, and Testing Digit Manipulation (00:27:05)
This Nugget applies the topics from the previous Nugget (regular expressions, calling and called party transformations) into practical configuration. Topics include transformation-rules and transformation-profiles configuration.
14. Advanced Dial Plans: Calling Privileges with Class of Restriction (COR) (00:34:14)
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.
15. CME: IP Phones, VLANs, and Communication (00:35:15)
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.

25. Quality of Service: The Missing Ingredient (00:47:58)
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).
