VoIP does not require the use of VLANs, though VoIP is often run over a network with multiple VLANs. VLANs can be set up on switches to separate broadcast domains in your network and can allow for the use of layer 2 QoS (IEEE 802.1p). You can look for switches from manufacturers such as Foundry, Dell, Cisco, and Zultys. The pricing will depend on the manufacturer and the number of ports on the switch. You can easily hunt these down online.
