Course 133  Part 1: The Big Picture

We begin with a comprehensive high-level introduction to today's telecom network. We cover the concepts of broadband and convergence, the parts of the network, and the three key technologies - IP, Ethernet and MPLS including what they are and do. We explain how carriers implement a service end-to-end, and identify the standard services available today for residential, business and wholesale.

Next, we demystify the jargon and buzzwords and explain in plain English the fundamentals of VoIP: how voice is communicated in IP packets, what each component of a VoIP phone system, like softswitches and gateways, does, and protocols like SIP.

We cover the key technologies and concepts in IP networks reviewing basic circuit configurations, using MAC frames to communicate IP packets, relaying packets from one circuit to another using routers, and implementing traffic management using MPLS.

We review the many flavors of VoIP for individuals, starting with Internet telephony: computer-computer VoIP over the Internet and various types of Internet-Public telephone network VoIP. We will trace a VoIP telephone call from a laptop over the Wi-Fi to the Internet, through a mobile network operator and finally to a cellphone in the class, identifying all the components, buildings, circuits and companies involved end-to-end.

Finally, we will review VoIP implementation options and the pros and cons for organizations including using SIP Trunking instead of expensive PBX trunks; getting VoIP from the phone company; renting a Hosted PBX; buying a call manager or softswitch; and cloud solutions.
