Join Lisa Bock for an in-depth discussion in this video Next steps, part of Learning VoIP and Unified Communications.
- [Lisa] Thank you for watching. If you're interested in learning more, please check out the IT segment of the library, where we add new courses all the time. If you want to learn about encryption, check out my cryptography course. For security basics, check out my Foundations of IT Security. If security and cryptography are up your alley, any course in the Ethical Hacking series will be well worth your time.
In addition, check out my latest release, Securing the Internet of Things: Introduction. Keep learning. I hope to see you again soon.
Lisa 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.
