ONFIGURING
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 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.
