We have DCSP set up on our switches as type 'differential services' only. &nbsp;No network prioritisation rules in place for types of service i.e. application port, device, protocol vlan or dscp mapping. <br />
<br />
I guess we need to create a rule and specifiy voice or data vlan high or low priority?<br />
<br />
Thanks

So we are having issues (albeit intermittently) with our voip phones poor quality. &nbsp;There are times where the calls are quiet, distant, echoey and sometime jittery.<br />
ISP says nothing wrong.<br />
SIP provider says all ok.<br />
<br />
Next thing i would like to change is settings on the switch, based on ping tests to the voice and data vlans on the hp poe 2910al switch averaging 4ms, but at times peaking at c150.<br />
My networking is a little limited...<br />
<br />
WOuld a rule on the l3 switch help? &nbsp;Currently has differential setup.<br />
See what i'm thinking attached.

Qos on L3 Switch?

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

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

IP Telephony

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.
