I have a central CM system with 3 remote sites connected over an IP WAN. I want to say only allow 10 calls accross the WAN an no more. what is the best way to do this i.e I can see a g.711 call uses 64K and g.729 uses 8 k do I just need to multiple these by 10 to work out how much bandwidth I need?
You can use Locations based Call Admission Control in CCM to accomplish this. For locations calculations, CCM uses 80k for G.711 calls and 24k for G.729 calls to accomodate overhead. So, if you're using G.729 across the WAN to a particular location and want to allow 10 calls, you would set your locations bandwidth to 240k. Take a look at the following links.
It depends on the video bandwidth you have configured for your Regions. If you configure 384k for video (which also includes audio), you could get 2 calls. The H.263 video codec uses 320k for video plus audio and overhead. The locations video bandwidth does not include overhead.
These are the paths to get to each CCX logs through CLI. They may be helpful if you are having issues accessing RTMT or downloading logs through it.
If you want to download them you have to prefix "file get " and you can add one of the options (re...
