You can assign a Quality of Service (QoS) priority level to video and voice calls
using either pre-configured system settings or by creating your own settings.
Quality of Service settings involve configuring
Service (QoS) DiffServ Code Point value in the IP header of outbound packets.
Routers on the network that support QoS can give preferential treatment for
bandwidth, latency and jitter to such coded packets and facilitate the efficient
transmission of packets. You can set QoS parameters on the Gateway for voice
calls, video calls or both.
