We have a network with lets say core layer, distribution layer and access layer of nodes. We are interested in implementing IP Telephony by placing Call Managers in the core network nodes. If we do that, we think that there is no way of call admission control between distribution layer nodes and access layer nodes. If we place call managers in distribution layer nodes, it will be quite unefficient since these nodes are too many and it will be very difficult to administer (we are talking over 40 nodes...). Any suggestions?
so you really think that the three layers of hierarhcy will be a problem? I am asking this because I do not know what factors the CM takes into account in order to make decisions for CAC. I mean if it is just the value of a parameter (location) it looks at, I do not see why it cannot perform CAC between distribution and access nodes. Furthermore,if the distribution layer node "hides" the access layer nodes that are connected to it, then I will not have problems only on CAC but also in defining other parameters too, like device pools for example.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
