CUCM 12.5 Limit maximum number of concurrent calls

[Juan Delgado Gutierrez]

Hello All, 

The screenshot shown below corresponds to the relationship of a site location to the other sites locations in the same cluster. In this case, is the bandwidth shown for each location that pertaining to that pair or is it shared between all locations? If it is the first case, how could the number of total concurrent calls (to other sites + outgoing to PSTN) be limited from a site?

Thanks for your help.

The bandwidths to each neighbouring location are separate so in your example the "hub" Location (you don't show its name) is allowed 80k to each of those listed Locations, there are nine Locations listed so a total of 720k is allowed to the hub.   If there's another limit lower limit you could create an intermediate Location with connections to each existing Location including your current "hub", and remove any bandwidth allocations directly from "hub" to existing spoke.

Let's say your bandwidth from "hub" to "Intermediate" was set to 200k, and you left the spokes as they are at 80k. 

In that case calls to any one spoke would be limited to 80k, but total call volume to "hub" would be limited to 200k.
