Abstract

A method (130) for optimizing call service in a VLAN (134) including at least one Voice over Internet Protocol device involves determining the current traffic levels of the VLAN (134), then adjusting the priority handling of data packets (108) in the VLAN (134) in relationship to current traffic levels so that voice packets receive an optimum number of network resources (136). Default priorities are used when level of traffic is in a normal range (140). During times when network traffic is below the normal range, signaling data packets may be increased in priority (148) and when network level of traffic is above the normal range, the priority of all data packets except for voice data packets will be decreased (144).
