Solved: How many simultaneous calls can be made on a CUCM 6.1.4

We have a cluster of five UCM's on a 7835H2 platform. What is the limit of simultaneous calls that the UCM can proccess before it starts to throttle?

Thanks,

Albert

Albert,

According to the data sheet for CUCM 6.x:

Maximum of 100,000 busy-hour call completions (BHCCs) per Cisco Unified Communications Manager server and 250,000 per server cluster (configuration dependent)

A good thing to use would be the Cisco Unified Communications Sizing Tool. It is available at http://tools.cisco.com/cucst

Thanks,

Adam

Hi Adam,

I saw the same numbers in cisco documentation. I wanted to confirm this. I was not able to access the sizing tool you suggested.

Thanks,

Albert
