I'm trying to find out the maximum amount of calls active at any one time over a particular gateway/E1 PRI for a time period, what is the best way to do this? This gateway is controlled by CUCM 8.5 using MGCP.
I know how to view the live CallsActive counter, but I would like to be able to instantly grab those values for say the past two weeks. I've had a look at the performance log viewer but that does not appear to be a counter that is logged for a particular gateway/interface. The only relevant counter I can find is a CallsActive for the CUCM node.
