VoIP Fundamentals for Service Providers
Computer-Based Training (CBT)

In this course we will introduce some fundamental concepts and components that are important when discussing VoIP such as Session Initiated Protocol and H.323. We will look at a typical carrier network and define the components needed for a VoIP application, specifically at softswitches, media gateways, session border controllers, and various servers that may be present in the network, and define the roles of each one. We will also identify vendors of these devices, and indicate interoperability with ADTRAN equipment where applicable. We will discuss security issues in the VoIP network. We will look at solutions for these security issues, focusing on TLS, or Transport Layer Security, and SRTP, or Secure Realtime Transport Protocol.
