Configuring Quality of Service 709Auto VoIPVoice over Internet Protocol (VoIP) allows you to make telephone calls using a computer network over adata network like the Internet. With the increased prominence of delay-sensitive applications (voice,video, and other multimedia applications) deployed in networks today, proper QoS configuration willensure high-quality application performance. The Auto VoIP feature is intended to provide an easyclassification mechanism for voice packets so that they can be prioritized above data packets in order toprovide better QoS.The Auto VoIP feature explicitly matches VoIP streams in Ethernet switches and provides them with abetter class of service than ordinary traffic. If you enable the Auto VoIP feature on an interface, theinterface scans incoming traffic for the following call-control protocols:• Session Initiation Protocol (SIP)• H.323• Skinny Client Control Protocol (SCCP)When a call-control protocol is detected the switch assigns the traffic in that session to the highest CoSqueue, which is generally used for time-sensitive traffic.To display the page, click Quality of Service →Auto VoIP in the tree view.
