Detailed explanation-1: -What is VoIP Quality of Service? Quality of Service (QoS) is a method to prioritize network traffic going through a router to provide acceptable service to most users. Administrators put QoS in place to address audio quality issues. VoIP is susceptible to network congestion, resulting in echoes, lag, and dropped calls.
Detailed explanation-2: -In any VoIP system, QoS is a crucial concern. The goal is to determine how to ensure that packet traffic for a voice or other media doesn’t get delayed or interrupted due to interference from lower priority traffic.
Detailed explanation-3: -Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line.
Detailed explanation-4: -Strictly speaking, QoS is not required to make VoIP calls. QoS for VoIP is a way to enhance the voice quality to an acceptable level. Without this technology, your call might suffer problems due to packet loss, especially if other users are using video conferencing.
