Auto-VoIP Configuration
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.
