This section contains the following information:
This course is a foundation course for network planners, engineers, and operators of VoIP networks aimed at teaching the basics of underlying IP and VoIP technologies including IP Routing, Ethernet, Quality-of-Service systems, VLANs, and VoIP System components. It is suitable for students who have a limited background in IP and VoIP technologies. This course is not specific to MetaSwitch products but rather gives the broader vendor-neutral perspective on IP technology and is run in conjunction with our training partner Engineering Consulting Group (ECG). This course provides for focused learning on the tactical skills needed every day at VoIP carriers. At the end of the course, you will be able to:
- Read and understand a router configuration
- Perform fundamental configuration on a Cisco router, including special requirements for VoIP
- Plan, configure and troubleshoot Ethernet switching
- Understand and plan a VoIP network interfacing with multiple devices and carriers
- Understand and configure NAT, and understand its affect on VoIP calling
- Understand core VoIP component types and their interaction
It will help if you know how to access and change the network settings on your computer, and access a command prompt or terminal window.
The MetaSwitch IP Foundations for VoIP training course is a 5 day course. It runs from 9am to 5pm Monday-Thursday and then 9am-2:30pm on Friday to allow participants to get home for the weekend.
Check the course schedule to see what dates are scheduled for future courses.
The course is split into the following modules.
- M1 - IP Routing
The IP Routing module introduces the concepts of Internet routing using point-to-point links. IP Routers are at the heart of service provider networks, and a solid understanding of their capabilities makes design and troubleshooting possible. Participants learn the basic theories of IP addresses, subnet masks, and routing tables. Examples center on WAN (point-to-point) networks. Exercises ensure knowledge of precise router function and use Cisco syntax.
- M2 - IP over Ethernet
For many simple networks, Ethernet just works. But detailed knowledge of Ethernet's basics of operation will enable you to make solid design and operation decisions both in local and customer networks, and in a carrier core network. Auto-learning Ethernet Switches and Ethernet rings add significant capability but latent complexity. This module covers MAC addresses and transmission rules, mapping of IP addresses to MAC addresses with ARP, the differences between Ethernet hubs and switches, and the detailed operation of Auto-learning Ethernet switches. This module's exercises cover knowledge of exact Ethernet behavior, and include troubleshooting of Ethernet problems.
- M3 - Routing and Ethernet
This module covers specific issues related to IP routing on Ethernet. Participants learn to use Ethernet as a powerful tool both for local and distributed networks. IP Address management is covered in detail. The exercises are designed to provide thorough comprehension of routing and Ethernet transmission function; further, participants gain experience performing basic network planning and configuration on Cisco equipment.
- M4 - Real-Time Flows and QoS
This module covers the fundamental of Real-Time flows used for VoIP audio and video. Participants learn how Internet networks are optimized, and how to implement prioritization to make VoIP calling successful. The exercises involve troubleshooting audio problems, and basic interpretation of packet captures showing RTP media.
- M5 - Transport Protocols -- TCP and UDP
This module discusses the transport "middleware" used in IP networks, and how VoIP uses these systems. This module helps participants understand fundamental operation of protocols in IP networks.
- M6 - Firewalls and NAT
Firewalls and Network Address Translation are facts of life for VoIP operators, often appearing both at customer locations and in the network core. However, they both have significant effects on VoIP signaling and media. This module covers the basics of firewalling and NAT technology, how to implement and configure routers to perform these functions, and how to plan for VoIP deployments involving these. Participants will configure routers to perform these functions, and analyze the precise effects on VoIP.
- M7 - Dynamic Host Configuration Protocol
The Dynamic Host Configuration Protocol (DHCP) is used by most VoIP Customer-Premise Equipment to enable basic configuration. A solid basic understand is required to deploy CPE in large numbers. The exercises in this module let participants configure, test, and analyze DHCP behavior.
- M8 - Domain Name System
The Internet Domain Name System (DNS) provides a key function for IP applications. It plays a special role in location VoIP servers. This module introduces participants to the operation of the technology, including recursive lookups to root Internet servers. In the exercises, participants learn how queries traverse the Internet.
- M9 - VoIP Systems Overview
Once the underlying VoIP network is understood, this module introduces the foundational VoIP servers and devices, including SIP servers, registrars, Session Border Controllers, and PSTN Gateways, and CPE.
