VoIP Training in Tashkent

This three-day intensive course delves into the messaging and call flows of the Session Initiation Protocol (SIP) and its implementation in voice networks. By integrating theoretical foundations with practical application, the training utilizes protocol analyzer traces to facilitate explanation and troubleshooting. Participants will engage with real-world VoIP configurations, working with IP telephones, softphones, voice-enabled Cisco routers, and SIP-based IP PBX systems such as Trixbox.

Audience

This course is tailored for Network Planners, Designers, and Engineers who need a robust understanding of SIP and its critical role in modern voice communications.

Designed with a strong emphasis on practical application, approximately 40% of the course is dedicated to hands-on exercises and real-world scenarios.

This course is structured into two complementary sections: a theoretical foundation and a practical application component. The first section, spanning one day, provides an introduction to the SIP protocol, covering its underlying motivation, core philosophy, fundamental principles, and operational rules. It also explores how SIP is utilized to implement telecom services, with a specific focus on IP telephony and VoIP technologies. The second section, which lasts for two days, focuses on the practical aspects of service operation through hands-on laboratory exercises. Participants gain detailed insights into the configuration of SIP telephony architecture components, analyze SIP signaling at both the message sequence chart and internal message structure levels, and develop skills for addressing common issues, including security concerns and telecom fraud scenarios. Trainers will share their extensive experience in deploying, operating, and managing SIP telephony solutions, including virtualization and cloud-based approaches. The practical segment utilizes both SIP hardphones and softphones, alongside IP telephony servers such as Asterisk and FreeSWITCH. Participants are encouraged to leverage the trainers' rich technical and business expertise by submitting their own challenges and questions, which will be incorporated into the final wrap-up session to address immediate client needs. This training is designed for individuals with foundational knowledge and experience in telecom services, particularly in VoIP and IP networking.

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

During this instructor-led, live training, participants will acquire the skills necessary to deploy a VoIP system using Cisco CallManager Express.

Upon completing this training, participants will be able to:

• Grasp core VoIP concepts
• Learn how to operate VoIP equipment
• Configure CISCO routers for VoIP functionality
• Integrate VoIP and CallManager Express into their network infrastructure
• Configure CME features for SIP, SCCP, and soft phones
• Apply advanced configuration settings and features of CME

Audience

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

Format of the course

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

This intensive three-day course delves into the core principles of the voice protocols utilized to transport audio and video across packet-switched networks. Combining theoretical foundations with hands-on application, the training employs Wireshark for detailed explanation and troubleshooting. Participants will configure practical VoIP systems 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. Additionally, Cisco-specific voice training modules are available upon request. The syllabus also addresses call establishment between circuit-switched and packet-switched networks.

Roughly 40% of the course is dedicated to practical exercises.
