Voice Over Internet Protocol Specialist

Description:

This onsite course provides a comprehensive study of the key elements of voice over IP, or “VoIP”. The focus of this course is to provide an understanding of how VoIP and the components of VoIP for two-wire equivalent cable telephony services.  Key areas covered in the training will be circuit switched voice, Internet Protocol (IP), IP multimedia subsystem, session initiated protocol (SIP), PacketCable, peering and troubleshooting voice networks.

Recommended Audience:  

This course is designed for technical personnel responsible for design, integration, implementation and management of VoIP platforms. For example, this class would be beneficial to: network architects, back-office system managers, system engineers, technical operations managers, IP network administrators, wireless network planners, NOC managers and mid- to senior-level technicians, and engineering managers.

Prerequisites:

An understanding of the fundamental aspects of IP technology including addressing and packet switched operation

Course Objectives:

Upon successful completion of this onsite course, each participant will be able to:

  • Explain foundational concepts of VoIP, which includes Session Initiated Protocol (SIP) and Media Gateway Control Protocol (MGCP) signaling protocols, and also, media stream transmission using Session Description Protocol (SDP) and Real-time Transport Protocol (RTP).
  • Define the key elements of Circuit switched Voice (CSV) in a Public Switched Telephone Network (PSTN)
  • Describe the functional elements of an IMS Architecture
  • Discuss the benefits of the IMS using SIP protocols
  • Explain network basic management requirements for converged IP based networks
  • Discuss rudimentary QoS requirements and the mechanisms for implementing them
  • Demonstrate methods for integrating PacketCable technologies in an HFC network and interconnection with the CSV networks such as the PSTN
  • Review installation methods and troubleshooting for customer premise locations
  • Provide an overview of PacketCable
  • Describe VoIP-Peering as cost saving measure
