UC is a framework that enables voice, video, and data on a single network. Components necessary include terminals, applications, codecs, gateways, protocols, and network operations.
- [Narrator] Unified communications is a framework…that combines IP-based communications services,…such as voice, video, and data…on a single network that improves overall efficiency.…Most systems have several necessary components…that include terminals, applications, codecs,…gateways, protocols, and network operations.…Terminals are the end devices that interface with the user…and include softphones and computers.…
A softphone is a computer that looks like a phone…and it allows you to make phone calls using voice over IP.…It has a standard phone interface and handset…and many have a digital or video interface…for messages and presence information.…If using a computer as a terminal,…you'll need a headset or a microphone and a speaker.…Today there are many vendors and many choices…for unified communications applications,…which combines communication services…such as voice, videoconferencing,…email, and instant messaging…into a seamless business application.…
This allows participants to meet online…and share files and collaborate using multiple platforms…
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.
