SIP / Voice QosQuality of Service(QoS), which is used for prioritizing the packets
based on urgency which is set in part of the packet. It’s very important in the VoIP
communication environment since data can always be re-sent so it’s not urgency at all.
Please note that selecting QoS can not guarantee the voice transmitting will be
expedited all the way. It just can ensure the packets through WIFI-ATA will be filtered
based on QoS type. If your router or other network devices do not support QoS, your
voice packet will be queued somewhere between caller and callee. For more
information about the QoS, please check IETF RFC documentaries about IP ToS.
