Configure Auto-VoIP
Voice over Internet Protocol (VoIP) enables telephone calls over a data network. Because
voice traffic is typically more time-sensitive than data traffic, the Auto-VoIP feature helps
provide a classification mechanism for voice packets so that they can be prioritized above
data packets in order to provide better Quality of Service (QoS). With the Auto-VoIP feature,
voice prioritization is provided based on call-control protocols (SIP, SCCP, H.323) or OUI bits.
