calculate max concurrent calls in CUCM

[SJ SJ]

What is the best way to check maximum concurrent calls ( internal + external )in CUCM ?

If we check through RTMT in Call Activity - It is per minute basis. Can we change it to per hour basis ?

Have you tried the system reports in CAR?

Which exact report or tool can help me get the max concurrent calls that i get in one day period?

[Rolando Valenzuela]

I like to uses the "Summary by Phone Number" under System Reports -> Traffic

Because I always filter the traffic according to the internal endpoint.

Real time, only with RTMT and the counters you have, you can change the time they report.

Offline, as Rolando mentions, CAR would be the best option.

If you need more info than what CAR can offer, or need to customize the reports, then you need a 3rd party billing app.

Thanks. How to change the counter, to get real time stats on per hour basis ?

[Jaime Valencia]

Sorry, it was supposed to say that you can't change the time they report.

[Rolando Valenzuela]

Using CAR is not possible to have real time per se.

What you can do it to run the hourly report around 9:05am for example to have the stats from 08:00 - 09:00

I know this question is nearly a decade old, but in 2023 there are great alternatives to RTMT, one of which is our product here.  In fact charting all kinds of concurrency and utilization is one of many things it is designed to do well.  https://sideviewapps.com/products/cisco-cdr-reporting/concurrency-and-utilization
