L2 Features > Voice VLAN
Voice VLAN is a feature that allows you to automatically 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 specified MAC address / VLAN ID, the packets
will pass through switch with desired priority.
