Netgear FS526Tv2 - 24-Port Smart Switch with Gigabit Ports Guia Do Utilizador

VLAN 2 is the preconfigured voice VLAN without any preconfigured members. To help 
ensure that the sound quality of an IP phone is safeguarded from deteriorating if the data 
traffic on the port is high, configure the voice VLAN settings for ports that carry traffic from IP 
phones.

The global voice VLAN properties include the voice VLAN ID (by default, VLAN 2), Class of 
Service (CoS) on the VLAN, reassignment of the CoS tag value, and voice VLAN aging time. 
By default, the voice VLAN is enabled. However, if the smart switch does not process voice 
traffic, you can globally disable the voice VLAN.
