Active CUCM subscriber

Hi Chris

I have just stepped in Cisco Voice. As I have read some books, they tell that we have can maximum 4 active CUCM subscibers in the cluster, but how can we know that out of all max 8 subscribers, which ones are active and which ones standby?

Hi Vikas,

you can have max. of 8 SUbscriber servers supporting call processing in a cluster .

You can have three servers in a call manager group.

Aman is correct (+5), SRND should always be an authoritive source for such information and if fact does a very good job explaining different redundancy models, etc. 8 call processing nodes is the max, 16 in mega-cluster, but those are rare and need special approval from Cisco.

HTH,

Chris
