Practical SIP Telephony Training Course

This course is structured into two complementary modules: theoretical and practical. The one-day theoretical module provides an introduction to the SIP protocol, exploring its motivation, core philosophy, fundamental principles, operational rules, and its role in implementing telecom services, with a specific focus on IP telephony and VoIP. The subsequent two-day practical module allows participants to gain hands-on experience in service operation through laboratory exercises. These sessions offer detailed insights into the configuration of SIP telephony architecture components, SIP signaling analysis at both the message sequence chart and internal message structure levels, and strategies for addressing common issues, including security concerns and telecom fraud prevention. Trainers will share their extensive experience in deploying, operating, and managing SIP telephony systems, encompassing virtualization and cloud-based solutions. The practical component utilizes both SIP hardphones and softphones, alongside IP telephony servers such as Asterisk and Freeswitch. Participants benefit from the trainers’ rich technical and business expertise in IP telephony, with opportunities to submit personal problems and questions. These inquiries will be incorporated into the wrap-up session to address urgent client needs directly. 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) is a technology that enables users to place voice calls via an Internet connection rather than traditional phone 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 use VoIP equipment
• Configure CISCO routers for VoIP
• Implement VoIP and CallManager Express into 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 fundamental voice protocols utilized to transmit voice and video traffic across packet-switched networks. Combining theoretical instruction with practical application, the training employs Wireshark for detailed explanation and troubleshooting where applicable. Participants will configure VoIP environments using IP telephones, softphones, and voice-enabled Cisco routers. While this is primarily a generic VoIP curriculum, it leverages Cisco equipment to establish an IP backbone and voice gateways. We also offer Cisco-specific voice training options. Additionally, the course addresses call setup procedures between circuit-switched and packet-switched networks.

Approximately 40% of the course is dedicated to practical activities.
