Practical SIP Telephony Training Course

This course is structured into two complementary modules: theoretical and practical. The first module, spanning one day, serves as an introduction that explores the motivation, philosophy, fundamentals, and operational rules of the SIP protocol, alongside its application in implementing telecom services with a focus on IP telephony and VoIP. The second module, lasting two days, allows participants to master practical service operations through hands-on laboratory exercises. These exercises provide detailed insight into the configuration of SIP telephony architecture components, SIP signaling at both message sequence chart and internal message structure levels, and assist in understanding typical issues and troubleshooting, including security and telecom fraud aspects. Trainers will share their extensive experience in launching, operating, and managing SIP telephony, covering virtualization and cloud-based solutions. The practical component utilizes both SIP hardphones and softphones, along with IP telephony servers (Asterisk and Freeswitch). Participants benefit from the trainers' rich technical and business experience in IP telephony and can submit their own problems and questions, which will be included in the agenda's wrap-up session to supplement the training and address clients' current urgent needs. This training is designed for participants with basic knowledge and experience in telecom services, specifically VoIP and IP networking.

VoIP (Voice over Internet Protocol) enables users to make voice calls over an Internet connection rather than through 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 core principles of various voice protocols utilized to transmit voice and video traffic across packet-switched networks. The curriculum blends theoretical concepts with practical application, employing Wireshark for detailed explanations and troubleshooting. Participants will configure VoIP systems using IP telephones, softphones, and voice-enabled Cisco routers. While primarily designed as a generic VoIP course, 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.

The training comprises approximately 40% practical exercises.
