L2 Features > VLAN > Voice VLAN
Voice VLAN is a feature that allows you to place the voice traffic from D-Link IP phones to an assigned VLAN
to enhance the IP voice service. With a higher priority and individual VLAN, the quality and the security
of voice traffic are guaranteed. The Voice VLAN function will check the source MAC address / VLAN ID on
the incoming packets. If it matches the specified MAC address / VLAN ID, the packets will pass through with
desired priority.
