In addition to conducting a needs analysis, assessing the network in order to ensure it can handle the additional traffic efficiently and provide high voice fidelity with no delay or jitter.
Networks are complicated…and when dealing with voiceover IP traffic,…we may not have a lot of control…outside of the local area network.…However, on our own local area network, we do have control.…An organization has an internal data network,…and things are going well.…The next logical step is to implement a VoIP system.…When considering VoIP, you need to ask,…"Is your network ready?"…Many businesses want reliability and functionality.…
Adding voice to an existing infrastructure…that has been designed for data flow takes some planning.…The network must be able to ensure…it has a high-quality voice…that's mean opinion score of 3.5 to 4.2,…and that there are no dropped calls,…or no delay variation or jitter.…Now, what's jitter?…We'll try to explain it.…It's as if the audio is blurred.…For example, in this illustration, you see a clear image.…
Down below, you can sort of see what the image is,…it's blurred.…On a voice network, we don't want jitter.…A local area network, along with the technologies…and intermediary devices used to access the physical network…
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.
