Voice VLAN GS700TP Smart Switch Software Administration Manual Voice VLAN allows you to enhance VoIP service by configuring ports to carry IP voice traffic from IP phones on a specific VLAN. VoIP traffic has a preconfigured OUI prefix in the source MAC address. You can configure VLANs on which voice IP traffic is forwarded. Non-VoIP traffic is dropped from the Voice VLAN in auto Voice VLAN secure mode. Voice VLAN also provides QoS to VoIP, ensuring that the quality of voice does not deteriorate if the IP traffic is received unevenly. The system supports one Voice VLAN. There are two operational modes for IP Phones: • IP phones are configured with VLAN-mode as enabled, ensuring that tagged packets are used for all communications. • If the IP phone's VLAN-mode is disabled, the phone uses untagged packets. The phone uses untagged packets while retrieving the initial IP address through DHCP. The phone eventually uses the Voice VLAN and starts sending tagged packets. The Voice VLAN menu contains the following options: • "Basic" • "Advanced" Basic The Voice VLAN Basic menu contains the following options: • "Properties" Properties The Voice VLAN Properties screen contains information about Voice VLAN on the device, including the ports enabled and included in the Voice VLAN.

You can configure VLANs on which voice IP traffic is forwarded. Non-VoIP traffic is dropped
from the Voice VLAN in auto Voice VLAN secure mode. Voice VLAN also provides QoS to VoIP,
ensuring that the quality of voice does not deteriorate if the IP traffic is received unevenly. The
system supports one Voice VLAN.
