Dont Need QoS

Many customers don't turn on QoS for a variety of reasons and, often, these reasons are valid. Some customers decide to run parallel voice and data networks. In other words, they use the IP components such as Ethernet switches for connectivity, but they isolate voice Ethernet switches from data Ethernet switches. QoS is less of a requirement in these cases.

Generally speaking, maintaining proper QoS is a good idea any time a company is running fully converged applications and users on the same network, particularly where voice, video, and data are all being used. Furthermore, voice does not always take priority. Key video sessions, financial transactions, and daily updates often require priority on the network as well.
