1148 Configuring Auto VoIP
Auto-VoIP is limited to 16 sessions and makes use of the switch CPU to 
classify traffic. It is preferable to use the Voice VLAN feature in larger 
enterprise environments as it uses the switching silicon to classify voice traffic 
onto a VLAN.
How Does Auto-VoIP Use ACLs?
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.
