VoIP Training in Sofia

This course comprises two complementary modules: theoretical and practical. The first module 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 focus on IP telephony and VoIP. The second module, spanning two days, allows participants to master practical aspects of service operation through hands-on laboratory exercises. These exercises provide detailed insights into configuring components of the SIP telephony architecture, analyzing SIP signaling at both the message sequence chart and internal message structure levels, and understanding typical problems and troubleshooting scenarios, including those related to security and telecom fraud. Trainers will share their experience in launching, operating, and managing SIP telephony, including virtualization and cloud-based solutions. The practical portion utilizes both SIP hardphones and softphones, along with IP telephony servers (Asterisk and Freeswitch). Participants benefit from the trainers' extensive technical and business experience in IP telephony and can submit their own problems and questions. These will be incorporated into the agenda's wrap-up session to supplement the training and address the clients' current urgent needs. The training is designed for participants with 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 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:

• Understand 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 intensive 3-day hands-on course delves into the core principles of voice protocols designed to transport audio and video traffic across packet-switched networks. Blending theoretical knowledge with practical application, the curriculum utilizes Wireshark for explanation and troubleshooting where appropriate. Participants will configure VoIP solutions using IP telephones, softphones, and voice-capable Cisco routers. While this is primarily a 'generic' VoIP training program, it leverages Cisco equipment to establish an IP backbone and voice gateways. We also offer specialized Cisco-specific voice training. The syllabus additionally addresses call establishment between circuit-switched and packet-switched networks.

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