You will not be able to "cluster" this solution. CallManager needs to have Publisher and then Subscribers. Your Subscribers are basically your "cluster" servers. They must be all the same MCS server platforms.
I would head on down to the Cisco Store and purchase a new 7835 for your subscriber. In fact, since you have 3000 phones, I would even go
Is it possible to communicate from one cluster to another cluster,is it required to trunk or otherwise what we can do...plz suggest.Is it possible through this way we can allow 3000 ip phones in our network through clustering with one cluster of 7835(2) & another cluster is of 7815(2) .
Yes, sorry about that. I did not understand exactly what you were asking. With ICT (Intercluster Trunks) you can communicate between any version of CallManager and MCS platforms. The cluster will be able to display callerID information, etc. Just setup the Route Points and Dialing patterns for each cluster so they can communicate.
i am asking about intercluster trunk(non-gatekeeper controlled )through we can communicate between two cluster? so how can we do this i don't no and it's right solution or not ? my aim is finaly using this 4 no of server we can support 3000 ip phone.
it's a little hard to understand what you want or are trying to say:
These clusters are separated and have no current connection between. You can create a ICT between the two clusters for dialing between clusters.
Extension 4000 on Cluster A needs to dial Extension 4000 on Cluster B. To do this, you will need to setup an access code such as "6" then dial 4000. This tells CallManager on Cluster A to push the digits out the ICT trunk when a "6" is used in the string followed by XXXX.
If you have unique digits on each Cluster, such as Cluster A extension 4000 wants to dial Cluster B Extension 5000, then a simple route pattern is all that is needed. (Route Pattern 5xxx -----> ICT to Cluster B)
ICT between CallManager clusters do not have a limit on the number of calls it can handle. Bandwidth determines this. If the Cluster A and Cluster B are on the same LAN, and the switch they are plugged into can handle this traffic, then there is no problem. If they are geographically separated, then you will need to factory in bandwidth between the clusters. Typically, G.729 between sites are used, which I think is 45k, but cant recall.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
