You can centralize your gatekeeper, I would divide the zones so that each cluster gets admission for the bandwidth it is requesting... the problem, of course, is that zone bandwidth end-to-end will be denied...<br><br>You also need to modify the BRQ Enabled service parameter in CCM to True to ensure it can dynamically change bandwidth...

I assume I need a gatekeeper for each cluster. But I have a problem with units. CallManager is asking for 64K for a g711 call, but Polycom is asking for 768K for a 384K video call.<br><br>Would I use via zones help with CAC?
<br><br>Should I have a gatekeeper at each hub and subhub location?<br><br>Thanks for the help,<br><br>-Patrick<br><br>________________________________________<br>From: Jonathan Charles [mailto:<a href="mailto:jonvoip@gmail.com">

<br><br>You need a Gatekeeper... Have all of the endpoints point to it and use the GK for CAC.<br><br>Also, build a GK-controlled trunk from each CCM node to the GK so CCM can call the H.323 nodes... also build a route-pattern on CCM to point to the aforementioned trunk...
