In SolarWinds VoIP and Network Quality Manager you can set the precedence, or packet priority, of your network traffic. Setting precedence levels for your traffic enables you to better ensure high quality of service on your network. SolarWinds VoIP and Network Quality Manager employs a decimal Type of Service value specified on the SolarWinds VoIP and Network Quality Manager Settings page. For more information, see Configuring VNQM settings.

The Type of Service value used by SolarWinds VoIP and Network Quality Manager corresponds to the per hop behavior (PHB) and the Differentiated Service Code Point (DSCP) values as shown in the following table.
