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 provides a
classification for voice packets so that they can be prioritized above data packets, allowing
the switch to provide better Quality of Service (QoS). With the Auto-VoIP feature, voice
prioritization is provided based on the SIP call-control protocol or OUI bits.
Configure the Auto-VoIP protocol-based settings
To prioritize time-sensitive voice traffic over data traffic, protocol-based Auto-VoIP checks for
packets carrying the Session Initiation Protocol (SIP) VoIP protocol.
