VoIP Training in Thessaloniki

This course is divided into two complementary sections: theoretical and practical. The one-day theoretical segment covers the motivation, philosophy, fundamentals, and operational rules of the SIP protocol, along with its application in implementing telecom services, with a specific focus on IP telephony and VoIP. The subsequent two-day practical segment allows participants to explore the operational aspects of services through hands-on laboratory exercises. These exercises provide detailed insight into configuring SIP telephony architecture components, analyzing SIP signaling at both the message sequence chart and internal message structure levels, and assist in understanding typical issues and troubleshooting methods, including security and telecom fraud considerations. Trainers will share their extensive experience in launching, operating, and managing SIP telephony, including virtualization and cloud-based solutions. The practical portion is demonstrated using both SIP hardphones and softphones, as well as IP telephony servers (Asterisk and Freeswitch). Participants are encouraged to leverage the trainers' rich technical and business background in IP telephony by submitting their own problems and questions, which will be incorporated into the agenda during the wrap-up session to address current client needs. This training is designed for participants with foundational knowledge and experience in telecom services, specifically VoIP and IP networking.
