The Auto VoIP feature makes it easy to set up voice over IP (VoIP) for IP phones on a switch. 
From software release 10.0.0 on, the switch supports both protocol-based and OUI-based 

Auto-VoIP configurations.

In a VoIP system, various signaling protocols are used to establish the connection between 
two VoIP devices. Protocol-based Auto VoIP provides a better class of service (CoS) to data 
and signaling VoIP streams than to other traffic. The supported signaling protocols are 
Session Initiation Protocol (SIP), H.323, and Skinny Call Control Protocol (SCCP). 
Depending on your configuration, after VoIP packets are identified, the switch takes the 
following actions:

If you enable remarking, the switch remarks the voice traffic 802.1p priority with the 
configured priority at the ingress port to ensure that voice traffic always receives the 
highest priority throughout the network. You must enable egress tagging on the 
appropriate uplink port to let the switch carry the remarked priority to the egress port.

If you assign a queue, make sure that you allocate sufficient bandwidth to the queue to 
fullfil the priority treatment for VoIP traffic.

Queue assignment and remark 802.1p priority are mutually exclusive 
configurations. You can configure each configuration on a per-port basis.

After a call session completes and the call is disconnected, the QoS rules are removed.
