ECI – EMSP VOIP Course
Course Description
Gain essential data networking and Voice over IP (VoIP) knowledge in a single, week log class. In this course, you will learn how VoIP works, why VoIP works, and how to use VoIP. On the first day, you will configure an IP network using Cisco routers and switches, learning IP fundamentals in order to make VoIP easier to understand. The remaining four days will focus on VoIP and IP telephony. The course is 60% hands-on labs and 40% lecture. The lecture portion of the class uses technically detailed sides that illustrate the subject matter– text-only sides are kept to a minimum. In the skills-building labs, you will gain proficiency with some of the most popular VoIP software and hardware, such as Wireshark, trixbox (formerly Asterisk@Home)), Linksys Ethermet phone, SIP-based ATA, and SIP-based Server and PBX products and more.
What You’ll Learn in Class
- Core concepts of how Internet Protocol IP carries a VoIP packet
- Advantages and disadvantages of SIP Trunking
- Configure DHCP ad DNS to support IP telephony
- Real-Time Transport Protocol (RTP)
- Session Initiation Protocol (SIP) – Call set up, Instant Messaging, Presence
- Session Description Protocol (SDP)
- The role of endpoints, gatekeepers, gateways and MCU in an H.323 network
- SIP proxy, Session Border Controller (SBC), and SIP softswitch
- Media Gateway Control Protocol (MGCP) analysis
- MGCP architecture
- A technical comparison of H.323, SIP, and MGCP
- How to implement QoS to ensure the highest voice quality over your IP networks
- The impact of jitter, latency, and packet loss on VoIP networks
- How to use Wireshark to decode and troubleshoot RTP, SIP, MGCP, and H.323 call flows
- Configure the trixbox Softswitch and SIP proxy
- Configure SIP gateways and softphones
Who Needs to Attend
This class is for people who need to understand VoIP technology. IT managers, technical sales/marketing personnel, consultants, network designers and engineers, product design engineers developing integrated-services products, telecom technicians and managers integrating PBX services within data networks, and systems administrators who will manage a converged network would benefit from this course.
