Course details
Today, when you make a call, you are most likely using Voice over IP (VoIP). VoIP uses the existing internet and network to transfer and route voice traffic in IP packets. In many cases, it is a part of a Unified Communications (UC) system, which integrates VoIP, video, email, and instant messaging into one seamless business application. In this course, learn about UC and its many layers so you can integrate UC and VoIP into your business network.
Instructor Lisa Bock compares the traditional Public Switched Telephone Network (PSTN) to VoIP and discusses the components necessary for VoIP to be possible. Lisa reviews digital codecs, protocols for data transport, and intermediary systems such as translators and mixers. Lisa then reviews business integration and the importance of conducting a network assessment prior to implementation. Lisa wraps up with a discussion on how ensuring quality of service (QoS) in a VoIP network minimizes latency and jitter and the importance of VoIP security.
