We have a 3750G we just dropped in. Hanging off it are 2 2970's. I want to enable QoS, and set the uplinks voice packets to have the highest priority on the LAN/WAN. We have 1 2970 across a Tsunami 45 wireless connection. Everything has been working fine; however, I am concerned that a large data stream will use the bandwidth leaving a VoIP call to drop or go bad. How would I go about doing this. We use the Avaya IP Office system.
