7/20/2017Lisa Bock compares the traditional Public Switched Telephone Network (PSTN) to VoIP, and discusses the framework and components necessary for VoIP to be possible. She reviews codecs, including characteristics such as bitrate and voice quality; protocols for setup, communication control, and data transport; and media gateways, signaling protocols, and intermediary systems such as translators and mixers. Lisa then reviews business integration and the importance of conducting a needs analysis and network assessment prior to implementation. Learn about the many value-added services UC can provide, such as integrating VoIP with email, billing, management software, and other customer management systems. 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 to prevent malware, impersonation, hijacking, and denial of service attacks.

- [Lisa Bock] Did you know that today, when you make a call, you are most likely using voiceover IP. Voiceover IP continues to be a fast growing technology, that uses the existing internet and network, to transfer and route voice traffic in IP packets. In this course, I'll provide an overview of voiceover IP and unified communications. We'll take a brief look of how we move from the public switch telephone network to voiceover IP. I'll cover components of unified communication, including signaling gateways, translators, codecs, and protocols. Hello, my name is Lisa Bock and I am super excited to bring you this course, so that you can better understand voiceover IP and unified communications so that you can better manage your network. Are you ready? Let's get started.
