CUCM cluster requirement for 12K users

[Muhammad Irfan]

Dear Team,

Any design or recommendation for number of CUCM nodes required for 12K users.

I am planning for 4 CUCM nodes with 10K OVA template.

One dedicated for Publisher (TFTP, MOH). Two will be active and one subscriber will be in backup for both subscriber.

Any suggestion.

If you are a partner make use of the sizing tool. It can walk you through sizing options and even export the output to vmpt

Hi Irfan

to host a cisco Cluster for 12K users you can deploy on top of 3x BE7M and USE OVA files as blow.

Main will be publisher and rest as SUBs. for more details please use as mention by Srinivasn
