8 Auto-VoIP Commands Voice over Internet Protocol (VoIP) allows network users 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 ensures 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. The Auto VoIP module provides the capability to assign the highest priority for the following VoIP packets: • Session Initiation Protocol (SIP) • H.323 • Skinny Client Control Protocol (SCCP) Auto-VoIP borrows ACL lists from the global system pool. ACL lists allocated by Auto-VoIP reduce the total number of ACLs available for use by the network operator. Enabling Auto-VoIP uses one ACL list to monitor for VoIP sessions. Each monitored VoIP session utilizes two rules from an additional ACL list. This means that the maximum number of ACL lists allocated by Auto-VoIP is two. The Auto-VoIP feature limits the maximum number of simultaneous users to 16. Administrators should utilize the Voice VLAN feature for deployment of IP voice service in an enterprise network because Voice VLAN scales to significantly higher numbers of users.
