[amansoi_5]

Hi All,

I have two clusters A & B with different Call Manager Versions.I want the calls should be established between two clusters.

what all is required to be done i.e. min. basic config in call managers /any hardware is required ?

I assume that you dont have a GK in this scenario. Create a intercluster trunk on Cluster A (No GK Controllerd) and a Router Pattern pattern pointing phones in cluster B. follow the same for Cluster B.

Hi Asif,

That's right we do not have any Gatekeeper.

Further,if you could detail us the exact config to be done in CCM ,it would be great.What I undertsand is that CM version is not any limitaion on ICT?

configure an ict on each cluster and point to the ip, configure the inbound css on ict. Versions do not matter. Then use the ict on route patterns

Hi Aman,

Also ensure that IP reachability is there. Ping and check......
