“Voice over IP” mean many different things. We begin with how it got started: phone calls between individuals over the Internet. You will learn how VoIP telephone service works over the Internet with a practical demonstration of Voice over the Internet to a cell phone. We will trace the voice packets from end to end, through all of the devices, buildings, circuits and carriers involved, starting from a laptop in the class over the Internet and on to a cell phone in the class.

3. VoIP Implementations for Businesses

We will compare and contrast the various choices for a VoIP phone system for a business: implementing a Hosted PBX; replacing the PBX with a softwitch or Call Manager; upgrading an existing PBX; using a Softswitch as a Service; IP Centrex; and Cloud-based services from the phone company. You will gain the knowledge to differentiate VoIP architecture options and confidently discuss the pros and cons.

  1. Migration Options to a VoIP-Enabled PBX
  2. Premise Call Manager / Softswitch: PBX Replacement
  3. Cloud Services and Hosted PBX: SaaS - Softswitch as a Service

4. SIP and VoIP Call Flow

The open standard protocol used to set up Voice over IP phone calls is SIP. A standards-based VoIP systems must follow the Session Initiation Protocol. SIP defines the procedure and messages for setting up a phone call, or any kind of communication. We describe what SIP is, how SIP works, and the relationship between SIP and softswitches and call managers demystifying jargon like proxy server. Then we trace the steps to connect an IP phone call. In the end, you will understand how phone calls are implemented in VoIP telephone systems which in itself may be worth attending the course!
