SIP protocol in VoIP

 21 Hours

The course consists of two complementary parts—a theoretical and a practical one. The first part is a one-day introduction that covers the motivation, philosophy, fundamentals, and rules of operation for the SIP protocol, with a focus on how it is used to implement telecom services, particularly in IP telephony and VoIP. The second part, which spans two days, enables participants to gain hands-on experience through laboratory exercises. These exercises provide detailed insights into configuring components of the SIP telephony architecture, understanding SIP signaling at both message sequence chart and internal message structure levels, and addressing typical problems and troubleshooting, including security and telecom fraud aspects. Trainers will share their extensive experience in launching, operating, and managing SIP telephony services, including virtualization and cloud-based solutions for government. The practical part of the course uses both SIP hardphones and softphones, as well as IP telephony servers such as 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 during the wrap-up session to meet current urgent needs of clients. This training is designed for participants with a basic knowledge and experience in telecom services, specifically in VoIP and IP networking.

Practical Voice and Video over IP

 21 Hours

This three-day practical course covers the fundamentals of various voice protocols used to carry voice (and video) over a packet-switched network. This course combines theoretical instruction with hands-on practice, utilizing Wireshark for explanation and troubleshooting as appropriate. Practical VoIP configurations are implemented using IP telephones, softphones, and voice-capable Cisco routers. While this is primarily a generic VoIP course, it uses Cisco equipment to provide an IP backbone and voice gateways. We can also offer Cisco-specific voice training courses upon request. The course includes call setup between circuit-switched and packet-switched networks.

The course is approximately 40% practical, designed to enhance skills and knowledge for government professionals in the field of telecommunications.
