Configuring Auto VoIP
Voice over Internet Protocol (VoIP) allows you to make telephone calls using a
computer network over a data 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 will ensure high-quality application performance. The Auto
VoIP feature is intended to provide an easy classification mechanism for voice
packets so that they can be prioritized above data packets in order to provide
better QoS.
The topics covered in this chapter include:
• Auto VoIP Overview
• Default Auto VoIP Values

• Configuring Auto VoIP (CLI)
Auto VoIP Overview
The Auto VoIP feature explicitly matches VoIP streams in Ethernet switches
and provides them with a better class of service than ordinary traffic. If you
enable the Auto VoIP feature on an interface, the interface 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 CoS queue, which is generally used for time-sensitive
traffic.
