<div>Jason, </div> <div> </div> <div> Trunking is not required to set QoS DSCP or COS settings. Those markings are not found in the ISL or 802.1q header; they are found in the ToS byte of the IP header. When Cisco IP phones encapsulate the voice bearer traffic within the IP packet they set the ToS byte by default to the EF QoS value. Most people allow Cisco switches to trust this value and not remark the VoIP packet. </div> <div> </div> <div>Peter<BR><BR><B><I>"Wydra, Jason" <jwydra@Burwood.com></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <META content="Microsoft Word 11 (filtered medium)" name=Generator> <STYLE> <!-- /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0in; margin-bottom:.0001pt; font-size:12.0pt; font-family:"Times New Roman";} a:link, span.MsoHyperlink {color:blue;
