Practical SIP Telephony Training Course

This course comprises two complementary components: a theoretical foundation and a practical application module. The first part is a one-day introduction that covers the motivation, philosophy, fundamental principles, and operational rules of the SIP protocol, as well as its role in implementing telecom services, with a specific focus on IP telephony and VoIP. The subsequent two-day segment allows participants to master practical service operations 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 understanding typical issues and troubleshooting techniques, including those related to security and telecom fraud. Trainers will share their extensive experience in launching, operating, and managing SIP telephony solutions, encompassing both virtualization and cloud-based approaches. The practical sessions utilize SIP hardphones, softphones, and IP telephony servers (Asterisk and FreeSWITCH). Participants can leverage the trainers' rich technical and business expertise in IP telephony by submitting their own challenges and questions. These will be integrated into the agenda during the wrap-up phase to address the clients' immediate needs. This training is designed for participants who possess foundational knowledge and experience in telecom services, specifically within VoIP and IP networking.

VoIP (Voice over Internet Protocol) is a technology that enables users to make voice calls over an Internet connection rather than through traditional telephone lines.

In this instructor-led, live training session, participants will gain the skills necessary to establish a VoIP infrastructure using Cisco CallManager Express.

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

• Comprehend core VoIP concepts
• Master the utilization of VoIP hardware
• Configure CISCO routers for VoIP applications
• Integrate VoIP and CallManager Express solutions into their existing networks
• Set up CME features for SIP, SCCP, and softphones
• Utilize advanced configuration settings and functionalities of CME

Target Audience

• Managers
• System administrators
• Software and support system developers
• Technicians
• Network engineers

Course Format

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

This three-day hands-on course explores the core principles of the various voice protocols employed to transport voice (and video) over packet-switched networks. The curriculum blends theoretical knowledge with practical application, utilizing Wireshark for explanation and troubleshooting where relevant. Participants will configure VoIP using IP telephones, softphones, and voice-capable Cisco routers. While this is primarily a 'generic' VoIP course, it leverages Cisco equipment to establish an IP backbone and voice gateways. Cisco-specific voice training courses are also available upon request. Additionally, the course addresses call setup procedures between circuit-switched and packet-switched networks.

Roughly 40% of the course is dedicated to practical exercises.
