Practical SIP Telephony Training Course

This course is divided into two complementary sections: theoretical and practical. The first section offers a one-day introduction that covers the motivation, philosophy, fundamentals, and operational rules of the SIP protocol, as well as its application in implementing telecom services, with a specific focus on IP telephony and VoIP. The second section, spanning two days, allows participants to master practical service operation through hands-on laboratory exercises. This part provides detailed insights into configuring SIP telephony architecture components, analyzing SIP signaling at both message sequence chart and internal message structure levels, and helps in understanding common issues and troubleshooting techniques, including security and telecom fraud aspects. Trainers will share their extensive experience in launching, operating, and managing SIP telephony, including virtualization and cloud-based solutions. The practical component utilizes both SIP hardphones and softphones alongside IP telephony servers (Asterisk and Freeswitch). Participants can benefit from the trainers' rich technical and business background in IP telephony by submitting their own problems and questions, which will be addressed during the wrap-up session to meet current client needs. This training is designed for participants with foundational knowledge and experience in telecom services, specifically VoIP and IP networking.

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

This instructor-led live training guides participants through the process of establishing a VoIP system using Cisco CallManager Express.

Upon completion of this training, participants will be able to:

• Grasp fundamental VoIP concepts
• Master the use of VoIP equipment
• Configure CISCO routers for VoIP functionality
• Integrate VoIP and CallManager Express into their existing networks
• Set up CME features for SIP, SCCP, and softphones
• Manage advanced configuration settings and features of CME

Audience

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

Format of the course

• A mix of lectures, discussions, exercises, and extensive hands-on practice

Over the course of three days, this hands-on training delves into the core principles of the various voice protocols utilized to transmit voice (and video) across packet-switched networks. Blending theoretical knowledge with practical application, the course employs Wireshark for clarification and troubleshooting. Participants will configure VoIP systems using IP telephones, softphones, and voice-enabled Cisco routers. While this serves as a 'generic' VoIP course, it leverages Cisco infrastructure to establish an IP backbone and voice gateways. Cisco-specific voice training options are also available. Additionally, the curriculum addresses call setup procedures between circuit-switched and packet-switched networks.

The training consists of approximately 40% practical exercises.
