SIP protocol in VoIP

 21 Hours

This course is structured into two complementary sections: theoretical and practical. The first section, lasting one day, provides an introduction that covers the motivation, philosophy, fundamentals, and operational principles of the SIP protocol, as well as its application in implementing telecom services, with a focus on IP telephony and VoIP. The second section spans two days and allows participants to explore practical aspects of service operation through hands-on laboratory exercises. This part offers a detailed insight into the configuration of SIP telephony architecture components, SIP signaling at both the message sequence chart and internal message structure levels, and helps in understanding typical issues and troubleshooting, including security and telecom fraud concerns. Trainers will share their experience in launching, operating, and managing SIP telephony, covering virtualization and cloud-based solutions. The practical segment utilizes both SIP hardphones and softphones, along with IP telephony servers (Asterisk and Freeswitch). Participants can leverage the trainers' extensive technical and business experience in IP telephony by submitting their own problems and questions. These will be incorporated into the agenda during the wrap-up session to supplement the training and address the urgent needs of clients. The training is designed for participants with foundational knowledge and experience in telecom services, specifically in VoIP and IP networking.

Practical Voice and Video over IP

 21 Hours

This intensive three-day course delves into the core principles of voice protocols designed to transmit voice and video traffic across packet-switched networks. Blending theoretical foundations with hands-on application, the training leverages Wireshark for clear explanations and troubleshooting, alongside the configuration of VoIP using IP telephones, softphones, and voice-enabled Cisco routers. While primarily a vendor-neutral VoIP curriculum, it utilizes Cisco infrastructure to establish an IP backbone and voice gateways. Cisco-specific voice training options are also available. Additionally, the course addresses call setup procedures between circuit-switched and packet-switched networks.

Approximately 40% of the course content is dedicated to practical, hands-on activities.
