You likely won't need a ton of QoS on your LAN unless you have a lot of unequal links. QoS for voice is usually a must at the WAN edge, but not really within a small to medium LAN.

all LAN ports are 100Mbps. I have a 4Gbps etherchannel between my core switch and distribution switch.

Regarding voice over ip, do I need to setup qos on my internal network the same as I would do on the WAN routers? I currently have a voice VLAN configured.<br />
<br />
interface Vlan212<br />
&nbsp;description VoIP<br />
&nbsp;ip address 10.2.0.1 255.255.255.0<br />
&nbsp;ip helper-address 10.1.200.16<br />

What else do I need to do or am I ok from an internal network perspective?

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).

Voice Over IP

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
