[cisco-voip] Voice and Video CallAdmission Control

[Patrick Mowry]

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.

Would I use via zones help with CAC?

Should I have a gatekeeper at each hub and subhub location?

Thanks for the help,

-Patrick

You need a Gatekeeper... Have all of the endpoints point to it and use the GK for CAC.

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...

Anyone integrating VTA and H323 video endpoints with CallManager 4.1(3)?
I'm looking for advise on Call Admission Control.  Almost all sites are
point to point T1 circuts, but not hub and spoke.  I have 2 main hubs 
with a CallManger cluster at each, but then there are sub-hubs (with 1
to 3 sites behind them) with no CallManager or local gatekeeper.

So is anyone dealing with call admission control in a wetup like this?
It was easy with polycom endpoints and an IPVC MCU, but VT Advantage
units are poping up everywhere.

Thanks,,
