Sorry if this is not really the real forum to discuss about this but I guess I need some clarification.
Here is what the CCNP-CCIE book says:
A CM Group in CUCM can have a prioritized list of 3 CUCM Server I'm OK with that
In a cluster there can be 20 Servers Max with only 4 with the Call Processing service running...
and this is what the SRND says:
Call Processing Subscriber
A call processing subscriber is a server that has the Cisco CallManager Service enabled. Once this
service is enabled, the server is able to perform call processing functions. Devices such as phones,
gateways, and media resources can register and make calls only to servers with this service enabled. As
shown in Figure 8-1, multiple call processing subscribers can be members of the same cluster. In fact,
Unified CM supports up to eight call processing subscriber nodes per cluster.
8 servers can have Call manager service running but only 4 as active ?
Thanks for the clarification guys.
I guess I have to follow the SRND but I m not sure I understand it clearly ....
The CVOICE book says that
