Hi, 

How much bandwidth is the video conferencing system pushing? Do you know if 4Mbps is enough? Is this SM used purely for video conferencing or is there other traffic bridged on this SM?

Thanks,

Sriram

Direction of bluring is also needed. From the specific clients perspective. Its important to know if this client sees a clear image or a blurred image and what the other participants see.
What is the data link ti this tower like? Youve indicated 33mbps but is that total available or used? What is the backhaul contention like? How many hops to each conference client? Are you trying to hairpin the connection through the same AP?

Realtime video is not like standard web acces and though like voip its not homogeneous enough to have good dscp settings. We need to know a lot more about your networks basic design and the current client request and deployment choices before we can give any kind of good advice short of, give them 25mbps up and down and see what happens.
