Practical SIP Telephony Training Course

This course comprises two complementary segments: theoretical instruction and practical application. The one-day theoretical component covers the motivation, philosophy, fundamentals, and operational rules of the SIP protocol, along with its role in implementing telecom services, with a specific focus on IP telephony and VoIP. The subsequent two-day practical segment allows participants to explore the operational aspects of services through hands-on laboratory exercises. These exercises provide detailed insights into configuring SIP telephony architecture components, analyzing SIP signaling via message sequence charts and internal message structures, and understanding typical issues and troubleshooting strategies, including those related to security and telecom fraud. Instructors share their extensive experience in launching, operating, and managing SIP telephony systems, including virtualization and cloud-based solutions. The practical sessions utilize both SIP hardphones and softphones, as well as IP telephony servers such as Asterisk and FreeSWITCH. Participants benefit from the instructors' rich technical and business background in IP telephony and are encouraged to submit their own problems and questions. These will be incorporated into the agenda during the wrap-up session to supplement the training and address clients' immediate needs. This training is designed for participants who possess basic knowledge and experience in telecom services, specifically in VoIP and IP networking.

VoIP (Voice over Internet Protocol) enables users to make voice calls via an Internet connection rather than through traditional telephone lines.

In this instructor-led live training, participants will learn how to set up a VoIP system using Cisco CallManager Express.

By the end of this training, participants will be able to:

• Grasp fundamental VoIP concepts
• Learn how to utilize VoIP equipment
• Configure CISCO routers for VoIP
• Implement VoIP and CallManager Express within their network
• Configure CME features for SIP, SCCP, and soft phones
• Work with advanced configuration settings and features of CME

Audience

• Managers
• System administrators
• Software and support system developers
• Technicians
• Network engineers

Format of the course

• Part lecture, part discussion, exercises and heavy hands-on practice

This three-day hands-on course explores the foundational voice protocols used to transmit voice (and video) across packet-switched networks. Blending theoretical knowledge with practical application, the curriculum utilizes Wireshark for explanation and troubleshooting where suitable. Participants will configure VoIP using IP telephones, softphones, and voice-capable Cisco routers. While primarily a 'generic' VoIP course, it leverages Cisco equipment to establish an IP backbone and voice gateways. Additionally, Cisco-specific voice training courses can be provided upon request. The syllabus also addresses call establishment between circuit-switched and packet-switched networks.

The course content is approximately 40% practical.
