our VoIP provider sent us the following configuration to apply to our ASA to QoS our VoIP traffic.
Can someone break down for me what exactly it is doing? are both instances of bandwidth in bps representative of the bandwidth I want reserved for VoIP? Or is one supposed to represent the amount of bandwidth set aside for normal web traffic? or something else?
Other than that ESI-priority matches traffic marked as AF33,CS5,EF and put it in priority queue but you need to define what is the reserved priority bandwidth in the same command.
Also very important to make sure that you don't have devices between phones and ASA which strips marking like a switch otherwise you will never match the policy (the switch should be configured to trust the markings using MQC or trust command - if supported)
Then the qos-realtime-shaper shapes the traffic at x amount which should be the link bandwidth and within that reserves traffic for voice by calling ESI policy.
