Online VoIP Training in Slovakia

This course is structured into two complementary components: a theoretical module and a practical module. The first component is 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 subsequent two-day practical module allows participants to gain hands-on experience in service operation through laboratory exercises. This provides detailed insight into the configuration of SIP telephony architecture components, SIP signaling at both message sequence chart and internal message structure levels, and aids in understanding typical problems 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, alongside IP telephony servers (Asterisk and FreeSWITCH). Participants can benefit from the trainers' rich technical and business experience in IP telephony by submitting their own problems and questions, which will be addressed in the agenda's wrap-up section to meet current urgent client needs. This training is designed for participants with basic knowledge and experience in telecom services, specifically in VoIP and IP networking.

VoIP (Voice over Internet Protocol) enables users to conduct voice calls over an Internet connection instead of relying on traditional telephone lines.

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

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

• Grasp fundamental VoIP concepts
• Learn how to operate VoIP equipment
• Configure CISCO routers for VoIP
• Integrate VoIP and CallManager Express into their network infrastructure
• 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

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

This intensive three-day course explores the foundational principles of the voice protocols utilized to transmit voice and video across packet-switched networks. Blending theoretical concepts with practical application, the curriculum employs Wireshark for detailed explanation and troubleshooting, while configuring VoIP environments using IP telephones, softphones, and voice-enabled Cisco routers. Although this is fundamentally a 'generic' VoIP course, it leverages Cisco equipment to establish an IP backbone and voice gateways. We also offer Cisco-specific voice training modules. Additionally, the syllabus addresses call establishment between circuit-switched and packet-switched networks.

Approximately 40% of the course duration is dedicated to practical exercises.
