Configuring Auto VoIP 114741Configuring Auto VoIPVoice over Internet Protocol (VoIP) allows you to make telephone calls using acomputer network over a data network like the Internet. With the increasedprominence of delay-sensitive applications (voice, video, and othermultimedia applications) deployed in networks today, proper QoSconfiguration will ensure high-quality application performance. The AutoVoIP feature is intended to provide an easy classification mechanism for voicepackets so that they can be prioritized above data packets in order to providebetter QoS. Because Auto VoIP is limited to 16 sessions, Voice VLAN is thepreferred solution for enterprises wishing to deploy a large scale voice service.The topics covered in this chapter include:• Auto VoIP Overview• Default Auto VoIP Values• Configuring Auto VoIP (Web)• Configuring Auto VoIP (CLI)Auto VoIP OverviewThe Auto VoIP feature explicitly matches VoIP streams in Ethernet switchesand provides them with a better class of service than ordinary traffic. If youenable the Auto VoIP feature on an interface, the interface scans incomingtraffic 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 thatsession to the highest CoS queue, which is generally used for time-sensitivetraffic.
