Segregation of Traffic

To ensure the best experience for users, it is highly recommended that administrators separate VoIP traffic from other network traffic by placing voice devices on a VLAN that is dedicated to voice functions. Also, users with USB-based devices should connect to a wired network rather than a wireless network whenever possible. Using a segregated VLAN for phone devices makes it much easier to leverage important network features such as Quality of Service (QoS) to ensure the best possible voice quality for end users. This configuration also serves to simplify monitoring, because endpoint devices are logically grouped at the network level.
