WaveJam

Hi All... I'm running a paid version of Broadwave v1.03 and my question is... Can I make ALL connections to my Broadwave server lock at something like 8 or 16 kbps? I'm not pumping music through it, in fact, its just a fire/police scanner. Quality doesn't need to be great. The other night I had 60 connections all locked in at 64kbps. My circuit can handle that but I believe 8 or 16 will be fine for what I'm doing and I want to prune as much traffic on my circuit as possible. Any suggestions? Thanks!
